····· lezzter Preis 25.75€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The present study provides experimental and mathematical methods for the understanding and quantification of the water fluxes and solute transport in heterogeneous layered porous groundwater systems characterised by differences in hydraulic conductivities.On the one hand, multi-layered porous groundwater systems with different hydraulic conductivities are characterised by a heterogeneous flow field, which causes a heterogeneous mass transport. On the other hand, extreme differences in hydraulic conductivities create regions of immobile water which influence the mass transport. These two different structural heterogeneities - variable hydraulic conductivities and immobile/stagnant water zones - were investigated experimentally in different laboratory aquifer models. The influence of immobile and stagnant water zones on mass transport was investigated with multi-tracer tests using tracers with different diffusion properties, namely uranine, bromide, deuterium, oxygen-18 as well as tritium-labelled water, in two-dimensional packed sediment column setups. Two separate column setups were filled. One column setup was filled with clay and sandy material while a second was filled with two different sand sediments. The observed tracer concentration breakthrough curves showed differences in peak concentrations and pronounced tails. Qualitative evaluation of tracer concentration curves led to the assumption that these effects were caused by a diffusive exchange of tracers between immobile and stagnant water regions. The measured data was modelled for the first time in porous media using the Single-Fissure Dispersion Model (SFDM). This model, which was developed for fissured aquifers, yielded a very good fit with all of the tracer concentration curves observed. Further quantitative evaluation of the system parameters (porosities of both materials, diameter of the water¬-bearing layer) in columns consisting of clay and sandy materials produced values that closely matched those independently known. This agreement of parameters confirmed that the model was valid for the heterogeneous systems tested. The model was able to calibrate the tracer curves and to estimate the parameters for the main water-bearing layer for the column consisting of two sandy materials with different hydraulic conductivities. The exchange into the bordering stagnant water occurred via both diffusion and an additional local transport by focusing the flow field into the more conductive material. Thus, in cases where the two materials have rather similar properties, the quantitative evaluation of the parameters of the less permeable layer is only possible when the porosity of that layer is known independently. Both types of experiments with a heterogeneous porous material showed that in groundwater sediments consisting of layers with different hydraulic conductivities the majority of mass is transported in the more conductive layer. The application of the SFDM in porous systems clearly proved that diffusive exchange into regions of immobile or stagnant water is an extremely important factor which has to be quantified. The study clearly demonstrated that multi-tracer experiments modelled with the SFDM are a very useful tool for solving the inverse problem, i.e. for quantifying parameters in such a heterogeneous porous medium.The influence of the local hydraulic conductivity differences on the flow field and mass transport was additionally experimentally investigated in a multi-layered large-scale indoor aquifer model (480 cm x 80 cm x 70 cm). A hydraulically more conductive layer caused a heterogeneous flow field which was traced by an instantaneous injection of uranine, bromide and tritium labelled water. Tracer observations performed in 2-D (vertical) at a high spatial and temporal resolution resulted in single tracer concentration curves. The tracer concentration curves clearly showed that multi-flow-path effects dominated. It was found that these can be adequately analysed using the Multi-Flow Dispersion Model (MFDM). The qualitative analyses showed that the more conductive sediment layer first focused the flow field, and that the water flux split into three different flow paths after leaving the focusing layer, as to be expected. The quantitative evaluation with the MFDM yielded the parameters of these flow paths. The volumetric water fluxes for flow paths with velocities of 2.7 m/d, 1.9 m/d and 1.3 m/d were estimated to be 55 %, 26 % and 19 % of the total water flux, respectively. It was also found that these flow paths were observed only over very short flow distances. After 2.5 m, all water fluxes characterised by different water velocities joined into one water flux which exhibited the mean water velocity but also showed higher dispersivity. This finding is extremely important for the further evaluation of pollutant migration and biodegradation.The present study clearly demonstrated that even in complex groundwater systems with a variety of structural heterogeneities the determination and quantification of different flow paths, and/or mobile and immobile water zones is possible by performing multi-tracer experiments using tracers with different diffusion properties, combined with an adequate modelling approach. ····· 10361193065

El cálculo de este factor requiere de registros pluviográficos que permiten identificar la variación de la intensidad de la lluvia en períodos cortos de tiempo. Como este tipo de información es escaso en el país, se utilizó una metodología denominada cascadas aleatorias cuyo origen es la teoría de la turbulencia y que se basa en la estructura fractal de los campos de lluvia con el fin de desagregar esta variable en intervalos de tiempo inferiores a los registrados. Se validó con 6 estaciones pluviográficas en la región central y occidental de Antioquia, y se aplicó posteriormente a 134 estaciones pluviométricas distribuidas en gran parte del territorio nacional. A partir de allí se encontró una relación de tipo exponencial entre la precipitación promedio anual y el factor de erosividad promedio dando como resultado un mapa de esta variable para todo el país. ····· 103612787

En este libro se propone una metodología basada en mediciones estacionales en campo de los forzadores climáticos, fluviales y oceanográficos y en modelación numérica de estos forzadores teniendo en cuenta su variabilidad intra-anual, para estudiar la evolución morfodinámica de desembocaduras. Esta metodología se validó en la desembocadura del río León, ubicada en el Mar Caribe Colombiano. Comparando las simulaciones de un año de evolución morfodinámica del sistema con mediciones de campo realizadas en el mismo año, se observa que con la metodología propuesta se pueden estimar con buena precisión las tasas de ingreso, salida y acumulación de sedimentos a escala intra-anual en las diferentes zonas que componen la desembocadura. ····· 103613000

Para lograr este objetivo se recabó información histórica del área de estudio obtenida de instancias como CNA, INEGI, Compañía Minera de Cananea, además de información generada ex profeso para el presente estudio. Esta última medición consistió en 6 cuantificaciones trimestrales de flujo de agua superficial en cinco puntos, y nivel estático en veinte pozos distribuidos a lo largo de la cuenca. Los resultados muestran que el acuífero se encuentra en equilibrio con tendencia en bajo grado a la pérdida de volumen de agua acumulado, aclarando que no se están tomando en cuenta los pozos explotados por la Compañía Minera. Si se sigue explotando el acuífero de la manera actual, en lo que se refiere a cantidad de agua extraída, no se corre riesgo considerable riesgo de sobreexplotación sin embargo, si se requiere aumentar la extracción, es necesario implementar sistemas de recarga artificial en las áreas crítica. ····· 1036121999

Los estudios estratégicos de transporte de carga a escala nacional, con los cuales las entidades del Estado apoyan la toma de decisiones, habían considerado únicamente los costos percibidos por los usuarios así, el reparto modal obtenido es sin duda ineficiente en términos sociales, debido a que los agentes no perciben la totalidad de los costos inherentes a cada modo de transporte en consideración, tales como emisiones contaminantes, ruido, accidentalidad y congestión.

Es wird nicht mehr von Fördertürmen, tiefen Tagebauen mit Baggern und Förderbrücken, kahlen Halden und Absetzern, von Abraum- und Kohlebahnen, Schwelereien, Brikettfabriken und zugehörigen Schornsteinen bestimmt, sondern von belebenden und bewachsenen Seen in mecklenburgischer Größenordnung, von Landwirtschaft auf ehemaligen Kippenflächen und von Wald auf Hochhalden. Mit diesem einzigartigen Landschaftswandel und ökologischen Lebensgewinn drohen freilich Braunkohlenbergbau und -industrie weithin in Vergessenheit zu geraten. Obwohl sie doch einst der wirtschaftliche Herzschlag Mitteldeutschlands waren, ihnen Zehntausende ihre Arbeitsplätze wie Existenz verdankten und der Osten Deutschlands davon nach 1945 schicksalhaft gezehrt hat!Aber Erinnerung ist möglich, Bergbau und Braunkohlenindustrie haben bleibende Spuren hinterlassen - nicht nur eindrucksvolle museale Zeugnisse, auch die Bergbaufolgelandschaft selbst mit ihren Tiefbau-Senungsgebieten, Tagebaurestlöchern, Abraumhalden bleibt dem Auge erkennbar und ist ungleich abwechslungsreicher, als es die alten Siedlungsböden der Leipziger Tieflandsbucht vor ihrer Zerstörung gewesen sind. So bietet sich heute und künftig dem Landschaftserlebnis eine vierte, die historische Dimension, zumal in den zurückliegenden 160 Jahren Braunkohlenbergbau und -industrie eine gewaltige technische und regionale Entwicklung durchlaufen haben. All dies, die ganze historische Technik der Braunkohlengewinnung und -verarbeitung sowie die einzelnen Reviere Mitteldeutschlands, erfasst die vorliegende Publikation im Überblick, bietet damit ein abschließendes Kompendium dieses ehedem dominanten Wirtschaftszweiges im mitteldeutschen Raum. Die geologischen Verhältnisse der Braunkohle bestimmen u. a. die technische Entwicklung der Braunkohlengewinnung und die Standorte der Braunkohlenwerke sowie deren Verschiebung im Lauf der Zeit. In der Geschichte der Bergbauechnik sind Tiefbau und Tagebau zu unterscheiden, eingeordnet in eine wechselvolle Geschichte in Abhängigkeit von den geologischen Verhältnissen und der Entwicklung der Technik. Die Verarbeitung der geförderten Braunkohle erfolgte - jeweils mit eigenständiger technischer Entwicklung - in der chemischen Braunkohlenveredelung (Schwelerei, Montanwachserzeugung), der mechanischen Braunkohlenveredelung (Nasspresssteinproduktion, Brikettierung) und der Erzeugung von Elektroenergie.

Damit leistet es einen intensiven, vielschichtigen und für Segler wie Nichtsegler gleichermaßen unterhaltsamen Beitrag zur Kultur des (Fahrten-)Segelns. Es löst empirisch ein, was vielfach gefordert wird: die Bestimmung des Räumlichen und dessen Rolle für die soziale Praxis. Mit der praxeologischen Perspektive wird die im Unklaren belassene dritte Dimension von Lefebvres Triade der sozialen Raumproduktion - der gelebte Raum - nicht nur eindeutig konturiert, sondern mit Inhalt gefüllt und dem Leser nahe gebracht. Im dynamischen Geflecht des seglerischen Raumes werden sowohl die geschichts- und traditionsreiche Kultur der Seemannschaft als auch die egalitären Communitas-Erfahrungen von Crew und Seglergemeinschaft gelebt und weiterentwickelt. In der Liminoidität des Meeres wird der Segler auf seine eigene Handlungskompetenz verwiesen und gleichzeitig lose in eine identitäts- und zusammengehörigkeitsstiftende Gemeinschaft eingebunden.

The hydrochemical differentiation of the salinization processes is very complex as there is considerable hydrochemical variability due to superposition of different processes: marine intrusion, recycling of wastewaters, continental saltwater contribution and pollution phenomena by agricultural activities. In this book, we try to describe the hydrological processes in the Korba coastal plain (NE of Tunisia) using hydrochemical data, correlation matrices and factor analysis to provide evidence of salinization processes. The application of Multivariate Statistics Techniques based on Principal component Analysis and Hierarchical Cluster Analysis has lead to the corroboration of the hypotheses developed from the hydrochemical study. Two factors were found that explained major hydrochemical processes in the aquifer. These factors reveal the existence of an intensive intrusion of seawater and mechanisms of nitrate contamination of groundwater. ····· 1036125249

However, the regular monitoring of glaciated terrains becomes difficult because of their inaccessibility and hindrance in collection of data through field methods. Thus, Remote Sensing and GIS serve as a useful technique to catalogue the changes in the glacier and understanding the climate change phenomenon. The results in this study show that satellite data can be used for extracting the quantitative and qualitative parameters of glaciers.

PM10 concentrations on days with Saharan dust contribution are higher than the average daily values recorded under no influence from Saharan dust. PM10 maximum concentration is observed simultaneously over the most studied sites. Satellite imagery as well as the aerosol and dust maps evidenced dust plumes transported from North African desert reaching the Mediterranean Tunisian regions. We show that the air masses loaded with dust instigates the increase of PM10 concentration and temperature at the surface. This may be due to the green house effect and heating created by the dust layer over the Mediterranean Tunisian sites during the Saharan events.

Regional climate modeling, as a part of down scaling techniques, to enhance the regional details due to geographical forcing is a very useful technique for over coming insufficient aspects of the GCMs such as narrow mountain ridges, complex terrain and complicated land sea contrasts.

As a cheaper alternative to mobile crushing suggested some previous studies, selection of an optimal location for the crusher can reduce the haulage distance between the blasting and crushing phases without exposure to risk of the blasting phase, thus reducing the overall cost of operation. This book explores the use of a data-driven Geographic-Information-System (GIS) approach for selecting the optimal location of a stationary stone crusher. Due to the difficulty of integrating the influential geographical factors (blast radius, slope and elevation) experienced by previous attempts, the methodology was developed to fully integrate geographic abstractions associated with the major quarrying phases into an appropriate Multi-criteria Decision Making model.

The radiative forcing of BC is about 55% of that of carbon dioxide and larger than that of other green house gases. Beside the climate change, it also changes the microphysical properties of clouds and causes human health effects. BC emissions are increasing in Asia due to the rapid commercial and economic developments. To assess the behavior of BC in the atmosphere at regional scale, the variability in the BC mass concentrations caused due to the emissions, meteorology, long-range transport, and wet deposition, is needed. Since China is the major BC emitter in Asia, this book briefly discussed the variability in the BC mass concentrations accounting the emissions, long-range transport, and wet deposition in East Asian focusing on China. ····· 10361100067

Therefore, it is very useful to identify and map such areas in separate spatial data layers in order to assist the Environmental Impact Assessment (EIA) process at early stages of project planning. Remote Sensing(RS) and Geographical Information System(GIS) provides a great potential for identifying and mapping of such area and very little academic literature exists on how to best utilize these technologies for environmental studies. Traditional approaches to data collection and updating no longer adequate to provide updated information for environmentalists. This book, therefore, introduces alternative techniques for data collection, updating, identifying and mapping of environmentally sensitive areas using RS and GIS. These techniques should help to shed light on these new and existing RS and GIS technologies, and should be especially useful to students and professionals in environmental science or anyone else who may be considering utilizing RS and GIS for environmental studies. ····· 10361100188

Sealing capacity of cap rocks is a direct indication of possible hydrocarbon column within the reservoir rock directly beneath the cap rock. Assessing the sealing capacity is generally done by measuring the capillary pressure of the cap rock. The objective of this work is to do a direct measurement of capillary pressure for a typical cap rock in a reservoir and correlate that with the initial hydrocarbon column. The results show that the layers with high displacement pressure are indeed good seals for trapping hydrocarbons. Also, the measured displacement pressure is a good predictor for hydrocarbon column underneath such cap rocks. Use of capillary pressure measurements in cap rocks during the exploration phase is highly recommended. ····· 10361100196

The oil and gas that formed in the source rock deep within the earth moved upward through tiny, connected pore spaces in the rocks. Reservoirs are not underground lakes of oil reservoirs are made up of porous and permeable rocks that can hold significant amounts of oil and gas within their pore spaces. Most reservoirs contain oil, gas, and water. Technological innovation makes it easier to find new deposits of oil and gas and to get more oil or gas from each reservoir that is discovered. The reservoir performance is predicted by mathematical modeling of the reservoir or reservoir simulation. The initial oil, gas, water saturation and pressure are specified. Oil Shales are usually fine-grained sedimentary rocks containing relatively large amounts of organic matter from which significant quantities of shale oil and combustible gas can be extracted. Included in most definitions of oil shale, is the potential for the profitable extraction of shale oil and combustible gas or for burning as a fuel.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Soil erosion is a wide spread phenomenon in Uganda`s Lake Victoria Basin (LVB). Choice of appropriate conservation practices depends on accurate quantification of the magnitude of damage. Variability across a toposequence on catchment level makes assessment studies technically difficult and economically not feasible. However, Geographical Information Systems (GIS) can capture spatial variability. A GIS-based Universal Soil Loss Model was initialized and used in this study to 1) validate the predicative capacity of the initialized GIS USLE model across the major land uses and soil types in the microcatchment, 2) Quantify the on-site damage in terms of soil loss, soil structure deterioration and nutrient loss. Run-off plot approach was used to collect runoff and sediment for soil and nutrient loss quantification. USLE parameters were obtained from: mean annual rainfall, soils map, Topomap, aerial photographs and satellite images using modeling operations in ILWIS. Applicability of the GIS-based USLE was demonstrated but calibration is essential. Land use had stronger influence on soil loss than slope. ····· 10361101498
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The primary mechanism for coal bed gas recovery at the Powder River Basin is by dewatering of the coal reservoir. Managing the produced water associated with gas recovery represents a significant issue. This book describes time-lapse crosswell seismic experiments that were designed to monitor and evaluate the spatial efficiency of the dewatering process. Results from the time-lapse tomograms show that the spatial distribution of the P-wave velocity changes approximates 6 percent above the coal as well as inside the coal layer. This difference can be attributed primarily to pore fluid saturation occasioned by the dewatering process. The observed changes are consistent with coal physics models and observations from production data and they demonstrate feasibility to monitor the reservoir production process. Results further suggest that produced water comes from the sandy-shale directly above the coal and that pressure drawdown in the coal is not spatially efficient. This book shows that time- lapse seismic can provide valuable information for reservoir process monitoring, optimization and management during reservoir production process. ····· 10361101680

The concentration of snow in this area is main hydrological resource for Pakistan. Accurate mapping of snow for this area is inevitable for the forecasting of snow-melt discharge for flood control, energy production and irrigation. MODIS snow-cover product (MOD10A1) is generated through an automated procedure which detects and masks clouds from snow surface using a global default algorithm. This distinction is challenging since snow and cloud have comparable reflectance and often comparable temperatures. The accuracy of snow map depends on the accuracy of the cloud mask, that entirely relies on thresholds which may be different in different regions. In this book, development of a regional based snow mapping algorithm is discussed for Northern Pakistan using MODIS data for the period of 2000 to 2008. The results are compared with the MODIS cloud mask in daily snow cover product (MOD10A1). The algorithm can be used for water resource management, as it improves the identification of snow by reducing the spectral overlaps between clouds and snow. ····· 10361114077

This meridionally aligned dipole rainfall anomaly configuration is captured only in the dominant principal component making it possible for the opposing rainfall anomalies of the two regions to have a common trigger. However, ENSO which has typically been invoked as the main cause for significant rainfall variability over this region cannot adequately explain this dipole rainfall anomaly pattern. The analyses strongly indicate that the positive IODZM phase events lead to a rainfall dipole such that floods occur over the north east of the region (around Tanzania) at the same time as droughts over the south east of the region (Zimbabwe, northern South Africa). Contrary to conventional knowledge, the ENSO association to this dipole rainfall anomaly pattern is not robust but appears to be the result of the well known ENSO-IODZM connection ····· 10361146512

Therefore, it is worth to identify spatial distribution pattern of built-up area in a town. Remote Sensing (RS) and Geographical Information System (GIS) provide a great potential for urban data collection & spatial analysis and not much academic literature exists on how to best utilize these technologies for urban studies. Traditional approaches to data collection and analysis no longer adequate to provide updated information for urban planners. This book, therefore, introduces alternative techniques for data collection, updating, detection of built-up area change and unauthorised constructions, identifying urban spatial distribution pattern considering built-up area density.

Most disputes among holders of land are more related to the accuracy of cadastral surveying techniques. In contrast, the cost of surveying techniques is the major factor for a country with poor economy. Balancing these issues will be difficult for a country which has not yet implemented a modern cadastral system and has no standard surveying techniques. This book, therefore, provides a systematic accuracy test for two surveying techniques used for land registration. Handheld GPS receiver and high resolution satellite image are compared with real time kinematic (RTK) GPS. The comparisons are made for the area and coordinate of the parcel by calculating its relative percentage error and root mean square error respectively.

The CaFe model (Cellular Automata - Fuzzy Engine) applies an innovative workflow to connect the input and the output variables. All input variables are merged in a single thematic layer using the Sensitive Sum operator. It is a new fuzzy operator that employs a dynamic parallel connection between the input variables while taking into account their statistical correlation. As a result, the model does not require certain variables/data to run while it implements a reducible/extensible form of Knowledge Base which can include both data-driven and empirical rules. The simulation engine incorporates advanced Cellular Automata techniques which apply spatio-temporal multi-radius transition functions and support action in distance.

These algorithms are greatly affected by clouds and different land cover types such as land and water with inherent temperatures. This book, therefore, provides a new multi-temporal threshold algorithm for near real-time forest fire detection using geostationary satellites, supplemental to the existing algorithms. This algorithm is based on temperature in IR3.9 channel and the difference between IR3.9 and IR10.8 channels. The multi-temporal threshold algorithm proved to have higher fire detection rate (50%) as compared to MSG FIR-G (3.7%) when ground data from Portugal was used for validation. This superiority was also confirmed over Southern Africa when MODIS fire product was used for validation. This analysis shows the possibility of manipulating the temporal domain of geostationary satellites in monitoring highly temporal environmental phenomenon.

Consequently, rainfall analysis is the method most commonly used in forecasting such phenomena, and worldwide observations have contributed to identifying critical levels of rainfall, over given periods of time, for triggering debris flow. These analyses, however, inadequately address the complex combination of physical, hydrological processes and the mechanical analysis of slope stability. More particularly, the location of debris flow initiation has been analyzed only rarely within the context of this methodology. In fact, because debris flows generally exhibit high mobility and long run-out travel distances, resulting in extensive property damage and significant loss of life, it is essential that we understand the temporal and spatial probability of debris flow initiation when planning preventive measures and evacuation systems. This book proposed a model to simulate rain water infiltration on slope instability and travel distance of debris flow run-out. ····· 10361587

Calibration results using monthly predicted values generally matched well with the observed values of two USGS gage stations in the watershed. The simulated sediment yield was inversely proportional to the CRP areas, with an overall 30% reduction in annual sediment yield. Sediment yield was highest from wheat, general agriculture and corn fields. Mapping sediment yield determined priority areas for future CRP enrollment. Correlation analysis revealed a good inverse relationship between sediment yield and areas under CRP. Wheat fields accounted for about 71% of total phosphorus and 77% of total nitrogen lost in Texas County. Results from Patch Analyst showed an increase in grassland area, a decrease in number of patches, and an increase in average patch size.

The aim of this research was to map available evidence on climate-induced conflict, critically appraising literature and synthesizing the results by categorizing articles according to their theme. There are very few researches oriented to deal with the issue of climate-induced conflict. Evidence on climate/weather-induced conflict is more theoretically than empirically driven. A few of the empirical studies included were statistically and methodologically rigorous to analyze the links between climate change and conflict, however, the sample sizes and the time periods looked at were too short to support the arguments made. There is a shortage of meaningful evidence and too much uncertainty on the links between climate change and conflict. Therefore, much in depth empirical investigation which links the two variables in relation to other social dimensions such as poverty and livelihood security is required before generalizing and making predictions about climate change and conflict. ····· 103613593

The main objectives of this book are to investigate the possibility of (UGS) development and feasibility of underground sour gas storage in a depleted fractured gas reservoir. Compositional simulation was employed to build a dynamic reservoir model, develop the history-matching phase of the reservoir, and construct injection/withdrawal (I/W) cycles. A systematic procedure was employed to determine optimum well pattern (well number, location, horizontal, vertical). Simulation study specified that the use of horizontal well is superior to vertical well because of less water production during storage cycles. Water cut, productivity and injectivity indexes of individual wells were considered as prominent factors to find the optimum well pattern. The results of the simulation showed that the presence of H2S and CO2 in the injected gas stream improved condensate production. It was found that UGS reservoir meet lower pressure at the end of I/W cycles in the case of underground sour gas storage. ····· 1036118781

The formation of secondary aerosols, in conjunction with the airborne particles of primary origin, has been recently recognized as a dominant process contributing to air pollution over urban areas. In addition, secondary aerosols are more hygroscopic and play an important role in the modification of the cloud activation processes by acting as cloud-condensation nuclei (CCN). Therefore, understanding chemical characteristics of primary emission sources and secondary aerosol formation is critical to evaluate their role in the modification in absorption properties and CCN activities.

It has been our goal to reduce the risk to people caused by earthquakes by observing warning signs in radon anomalies. We apply a critical phenomena model to the radon data. The anomalous increase in atmospheric radon concentration is studied in detail using the thermodynamic theory on the time-dependent evolution of damage of stressed rock and crustal fluid dynamics prior to catastrophic failure or an earthquake. Effects of radon emissions on atmospheric electrical conditions and preseismic electromagnetic phenomena are discussed in terms of lithosphere-atmosphere-ionosphere coupling. The radon data and other preseismic phenomena are linked to fluctuations in crustal strain before the earthquake.

The objective of the research was to assess, using remote sensing and geographic information systems technologies, migration of dunes and the effect of dune movements on distribution of associated wetlands. Aerial photographs from 1938 through 2003 were analyzed to track individual dune movements and wetland propagation and expansion. Based on review of aerial photographs, parabolic dunes have migrated 150 to 250 m since 1938, with 60% of the movement occurring between 1938 and 1977. Wetlands consistently trailed the dunes, and the distance of wetland movement was related to dune movement distances.

In this study, pile integrity testing data of 187 piles in two close sites located in Buyukcekmece, Istanbul are analyzed. The test method utilized in this project is the sonic echo method. The aim of this study is to detect occurrence of discontinuities along the pile axis. As the test data reflect the change in impedance, possible impedance diversity due to soil conditions must be known beforehand. In this manner, impedance difference caused by the discontinuities in the pile is distinguished and acquired. Using TNOWAVE`s SITWAVE application, pile integrity testing is simulated and signal matching procedure is executed. In order to achieve reliable results using SITWAVE, sufficient soil investigation must be performed to determine the soil layers and soil parameters properly.

Wheat plants were grown on alluvial, sandy and calcareous soils under salinity levels of 4, 8 and 12 dS/m of saturated paste extract (ECe) and supplied with constant rate of superphosphate (SP), cattle manure (CM) and 1:1 mixture of SP and CM. The results revealed that plants grown on the sandy soil were more susceptible to the adverse effects of salinity compared with that planted on the alluvial one, especially at 0 P. However, plants grown on the calcareous soil were moderately affected. In addition, varying soil type caused significant differences in the aboveground biomass and uptake of N, K, P and Zn in shoots and grains, where maximum values were attained in the alluvial soil followed by calcareous soil. Grains and straw yields and contents of N, P and K in the shoot tissue, grains and straw decreased significantly with increasing ECe from low (4 dS/m) to high level (12 dS/m). ····· 10361116142

Both dry (without cloud) and moist (with cloud) convection depend on the surface temperature. Surface temperature is of critical importance in several practical applications like human comfort and crop cultivation. In the climate change scenario too, variations in the surface temperature take the center stage. Therefore, prediction of surface temperature is important. The evolution of the temperature is governed by the energy equation and the surface temperature by the surface energy balance. Important components of the surface energy balance are radiation (incoming solar radiation, reflected solar radiation, incoming and outgoing longwave radiation), sensible and latent heat fluxes and heat flux into the ground (called ground heat flux).The present study addressed the above problem by using the data from a 10 m meteorological tower. Turbulent fluxes were computed using both profile and Eddy Correlation Method (ECM) and sensitivity of the fluxes for small calibration errors is evaluated and quantified the minimum data accuracies for flux measurement with the Profile method (PM). ····· 10361118206

An analysis of the relaxation timesshows that these processes are relevant in theseismic frequency band and drive the effective fluidcompressibility towards values higher than theunrelaxed values. Under full thermal relaxation between fluid and mineral, the effective compressibility is equal to the averageof the fluid adiabatic and isothermalcompressibilities weighted respectively by the heatcapacities of the fluid and mineral. On the otherhand, at the crossing of bubble point, in thelow-frequency regime a discontinuous variation influid compressibility exists. In these two relaxationprocesses, the difference in fluid bulk modulusbetween the unrelaxed and relaxed regimes, which isdirectly related to P-wave velocity dispersion, canbe as large as 0.5 1 GPa, depending on the fluid typeand gas saturation. ····· 10361118635

One such example is wastewater management projects. Wastewater management is still in its early stages in Lebanon like many other developing countries due to the nonoperational wastewater treatment plants. Wastewater is either discharged into sea, rivers or on open lands without treatment. Also, the the absence of effective wastewater management practices and delay in implementation has led the local communities to plan and implement their own arrangements for effective wastewater treatment facilities. This, however, raise a crucial question about the effectiveness of these facilities. This book aims to assess the effectiveness of existing wastewater treatment systems by testing effluent quality of the treated wastewater discharge, taking Chouf Caza in Lebanon as an example.

But in car-oriented cities, activities tend to spread out. This forces people to travel further and further for the same level of accessibility as before. So the main concern of transportation planning should be on moving people and goods rather than vehicles. In dense cities, public transport saves valuable space and energy compared to private transport and can make a healthy profit at the same time. Bangladesh is one of the most densely populated cities of the world. To serve this high density Dhaka City, the capital of Bangladesh, needs efficient public transport system. This can be facilitated by the introduction of BRT. In this study a design proposal is made for the blue route proposed in the Strategic Transport Plan for the city. Then the financial feasibility was analyzed using some popular tools like, break even analysis, benefit cost ratio, net present value, internal rate of return.

Here, few methods/approaches have shown for quantitative assessment of gas hydrate from seismic amplitudes. Seismic attributes like reflection strength, blanking and instantaneous frequency have been computed to identify gas-hydrates in absence of BSR (Bottom simulating reflector) or to ascertain whether a BSR is related to gas-hydrates.

The requisite small subset (pre-specified number) of eigenmodes are obtained by using shift and invert implementation of Implicitly Restarted Arnoldi Method (IRAM). It is analyzed that only 10-15% smallest eigenvalues and corresponding eigenvectors are sufficient to obtain the acceptable solution.

The high cost of subsurface data acquisition requires that they be collected in a judicious and effective manner. Previous approaches to the assessment and optimization of data collection schemes have generally considered the underlying models to be known and accurate. In reality, the complex nature of hydrogeologic environments renders available data prone to multiple interpretations and the system subject to alternative ways of representation by models.

The subsidence curves display initial dominantly decelerating subsidence, suggesting an extensional and thermal control possibly in a strike-slip setting during the depocentre formation on the other hand, subsequent accelerating subsidence with time suggests that the dominant control on the depocentre formation in SW Karoo was flexure of the lithosphere. Furthermore, siliciclastic cover in the Tanqua depocentre expanded from minimal values in the early Triassic (Early to Late Anisian) and to a maximum in the middle Permian (Wordian -Roadian) thereby accompanying a global falling trend in eustatic sea-level and favoured by a compressional phase involving a regional shortening due to orogenic thrusting and positive inflections (denoting foreland basin formation).

The impact of the CO2 capture and transport on power generation cost, including the benefits of atmospheric CO2 mitigation has also been determined. Power plants comprising 55.7% of installed capacity in Texas Gulf Coast as of 2008 were selected. Absorption amine technology was adopted for the CO2 capture. Bernoulli s equation was used to model the fluid transmission. Cost escalation factors were introduced into existing pipeline models to improve estimation. The analysis shows that cost of the pipeline transport is highly sensitive to escalations in labour, material and right-of-way costs. The percentage incremental generation cost for coal-fired plants is from 55-122% whilst that of gas-fired is from 9-13%. Some by-products from the CO2 capture could be sold to reduce generation costs. The results indicate 6-12% reduction in Texas Gulf Coast power plant annual emissions.

Hydrologic models are the standard tool used to generate continuous estimates of stream flow and regionalisation has been the traditional approach to model application in poorly gauged basins. The classical approach to regionalization is to calibrate against naturalized observed data, identify hydrologically similar basins, and then transfer calibrated parameter sets to the ungauged basins. One of the problems related to this approach is the relatively few basins for calibration in southern Africa (due to data quality and availability problems), resulting in huge uncertainties in the prediction process. This study proposes an a priori process to directly estimate parameters of the Pitman monthly rainfall runoff model based on physical basin characteristics. The approach is tested on selected basins in southern African. ····· 10361118598
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book assesses various processes and strategies of engaging disparate development stakeholders in urban governance and evaluates the experiences and capacities of civil society in urban development in Harare. A case is made that macroeconomic instability and other external forces such as globalization constraints, the legacy of colonialism, along with rapid urban population growth, institutional, financial and administrative incapacities, and outdated governance traditions, have resulted in failure of government to provide social services or even to maintain basic infrastructure. Consequently, civil society has stepped up to fill the gap. The effectiveness of civil society however, depends on the nature of its internal organization and operations, as well as its relationships with the state and other urban development stakeholders. Ultimately, since their roles are complementary and mutually reinforcing, civil society and the state need each other and must work together in order to achieve human sustainable development of all sectors of society. Anyone interested in urban development issues in Africa should find this book useful. ····· 10361118682

Moreover, there is lack of proper indicators and evaluation methods to assess the overall impact of these programmes. In the present book an attempt was made for assessing the impact of Chenani WDP of Udhampur district of J&k state, in terms of resource condition and availability. Both quantitative and qualitative parameters were used for impact assessment of the programme. The lessons learnt from previous (WDP) experiences could be very helpful in making future WDP s more efficient, economical and sustainable. Therefore, a multilateral approach with qualitative and quantitative indicators like carrying capacity, soil erosion level, people`s participation were used for measuring the impact of WDP on natural resources of the study area. ····· 10361119314

However, many of the earlier geophysical investigations were focused on eliciting the broad, deep-seated regional signatures in parts of the craton. Yet, there are very few reports of detailed crustal configuration of the region. Further, there are very few instances of semi-detailed geophysical investigations in the craton. Keeping this in mind, an area in eastern Dharwar craton was identified for 2D semi-detailed geophysical and remote sensing image analysis. Since, the area has its contiguity with Maddur-Narayanpet kimberlite field it forms the south and southeast extension. Therefore, motivated by this proximity, using a posteriori approach, published report of occurrences of kimberlites in Maddur-Narayanpet kimberlite field was reanalyzed to develop a sub-surface topographic criterion to identify zones with potential for occurrence of kimberlites. This criterion was then used to locate such zones in the study area. This book is very useful for practicing geophysicists in kimberlite serach. ····· 10361132231

A new combination approach consisting of a rational function transformation and a common under-relaxation technique is proposed to solve the finite element formulation of h-based form of Richards equation. Numerical studies show that this combination method outperforms previous numerical schemes in the sense that it can use larger time-steps and mesh sizes to produce acceptable results and also converge to a stable solution quickly in each time-step. Furthermore, the superiority of proposed approach is also identified when combined with different time stepping schemes in terms of efficiency that it takes less run time to produce solutions satisfying the requirements in accuracy.

VADASE is based upon a so called variometric algorithm able to retrieve in real-time the displacements of a unique receiver, with accuracies ranging from few centimeters up to a couple of decimeters. Eventually, VADASE was appointed as an effective contribution to GPS Seismology. First, the state of the art of GPS Seismology and the advantages and limitations that GNSS receivers can bring about with respect to seismology instruments are presented. Further, a review of the main applications that benefit from high-rate GNSS data availability is given, with an insight on earthquake and tsunami early warning systems. Then, the book illustrates VADASE functional model and the results obtained in several scenarios simulated by a Spirent GNSS data simulator. Importantly, receiver displacements achieved for real earthquakes by VADASE are assessed with respect to those obtained by the most used strategies in GPS Seismology (i.e. Precise Point Positioning and Differential Positioning). ····· 10361134173

Most studies carried out in this area have concerned classical archaeological excavations. However, the negative effects of the flowing groundwater are so significant that this area needs to be inspected much more rapidly and appropriate measures put in place to mitigate or prevent further damage. This book is concerned with the application of several geophysical techniques in investigations of regional geological features and an important local buried archaeological structure at the famous Saqqara necropolis cemetery. Combined interpretation of electrical resistivity and time-domain electromagnetic data provided important constraints on the deep regional geology of the Saqqara area. Of the methods applied in the archaeological study, georadar produced disappointing results because of the high conductivity of the shallow subsurface the shallow conductivity distribution was established from an electrical resistivity survey.

Entre los resultados obtenidos destacan los siguientes: Se observó un incremento generalizado de las producciones de escorrentía y sedimentos durante el periodo posterior al fuego. Los resultados indican que estos incrementos estuvieron asociados a un sellado de la superficie del suelo debido al impacto de las gotas de lluvia. Este fenómeno puede ocurrir incluso en suelos con una estabilidad estructural elevada. La respuesta de la vegetación fue un factor fundamental de control de la degradación posterior al fuego.

En la CM se presentan amplificaciones inusuales del movimiento sísmico así como incremento en la duración. La combinación de estos factores puede ser catastrófica para un gran número de edificaciones ubicadas sobre suelo blando. Los efectos de sitio, causados por la presencia de arcillas altamente compresibles, se identificaron como una causa primordial del daño ocurrido.

Although of strategic importance of these aquifers for local water supply and for agriculture use, there are not comprehensive studies and information about the thickness of the overlaying formations and the structure of the carbonate formations. The present research aims of clarifying these questions using geophysical prospecting methods. An integrated approach is used including apparent resistivity soundings, seismic refraction profiles and the available boreholes information in the region. A set of interpretation material was developed for simple 2D models and thus pseudosections for alpha resistivity and for the ratio beta/gamma resistivities using Wenner tripotential measurements are presented, in order to be used for the interpretation of the present and future field data.Finally the integration of all data suggests a structural model for the region and an evaluation of the thickness. ····· 10361929

Understanding colloid fate and transport in porous medium not only permits more effective protection of water supplies, but also allows for the development of more effective pollutant remediation strategies. Organic matter (OM) complicates colloid behaviour. To date the influence of OM on colloid mobility in porous media has been largely qualitative. This book presents research leading to the development of multiple-pulse column techniques that may be integrated with mathematical models to quantify the effects of OM on particulate colloid attenuation in saturated porous medium. Research has investigated how two groups of environmental organic compounds, humic acids and proteins, influence particulate colloid attenuation by saturated sand.

An extensive understanding of rain DSD and integral rain parameters finds applications in fields like satellite meteorology, cloud microphysics, soil erosion, micro wave communication and global climate. DSD and derived rain parameters data from 4 tropical stations for 10 years, which were measured using a Joss-Waldvogel Disdrometer and those at different heights, which were collected using a Micro Rain Radar are used. The Tropical Rainfall Measuring Mission (TRMM) and other satellite rain rate (3B42-V6) for the same period has also been used. The major results pertain to the development and testing of a model for the variation of DSD with rain rate in the tropics. The theoretical concepts regarding the altitudinal and temporal evolution of rain DSD could be proved. The evaluation of the vertical profiles of DSD and Z-R relations for tropical region is another result. This study has also brought out the need to have a closer look at the satellite retrieval. The behaviour of the rain rate at tropics and the possible effect of orography on DSD has also been brought out. ····· 1036118908

Shallow and deep stabilizations using ordinary Portland cement as binding agent and silica fume, blast furnace slag, fly ash, polypropylene fibres and steel fibres as chemically active and none active additives have been used to improve strength as well as to reduce compressibility of fibrous peat. Major evaluation tests used, were FVST, UCS, CBR, CUT, and Rowe cell consolidation tests. Disturbed (bulk) and undisturbed fibrous peat samples were also used for indexed property tests. For deep stabilization of peat, precast stabilized peat columns were tested for their role on shear strength, as well as compressibility of untreated or plain fibrous peat. PLT is used on plain and reinforced peat with various types of stabilized columns in a test tank, and the actual test results were compared with the answers obtained from FEM analysis. All types of test results used during the course of the research indicate that stabilization techniques used in either shallow (mass) or deep stabilizations improve the load bearing capacities of untreated fibrous peat, hence upgrading peat civil engineering properties. ····· 1036119208

Using transform methods, a general three dimensional point source semi-analytical solution for the drawdown response in composite clastic and naturally fractured systems separated by a leaky fault is developed. This solution is converted to line source for horizontal and vertical wells and plane source for hydraulically fractured wells, while treating the fault as a thin finite conductivity fracture. For the first time, it is documented that the intersection time between the long-time approximation of both observer pressure drawdown and observer pressure derivative is unique. Commercial simulator and field data from the Niger Delta was used to validate this model and direct synthesis of reservoir parameters from the resulting equations for various wells under different boundary conditions are examined. The result of this work is attractive where formation juxtapositions separated by leaky faults in the reservoir are suspected to allow flow from adjacent fields and where vertical permeability plays a major role in depletion. ····· 1036119534

This was combined with column experiments for monitoring the transport/precipitation processes. Thickened tailings discharge in Egypt did not allow grain-size/mineral segregation and therefore the critical amount of reactive mineral phases cannot be achieved. This, with high carbonate contents and high-temperature/low-water availability did not allow significant oxidation of sulfides and decrease hardpans possibility. Spigot tailings disposal in Germany with enrichment of reactive phases in certain lamina, combined with periods of raining and drying events enhances the process of hardpan formation. Hardpan development is highly enhanced in areas with high temperature, water content, high reactive minerals, repetition of drying/wetting cycles and long reaction time. This work shed some lights on the process of hardpan formation to minimize the environmental problems developed in inactive mine sites, especially those with high sulfide contents. ····· 1036120463

Climatic parameters like Temp., Precipitation, Wind Speed, Wind Direction, Solar Radiation are playing major role. Glacier s size, life span, growth and retreat all depend strongly on climate conditions. The Himalaya possesses all the three characteristics of glaciers viz. low, mid and high latitudes glaciers. In the extreme west the climate is purely sub tropic to mid latitudinal climate and tropical in the east. Therefore, Himalaya provides a unique opportunity to study the mass balance and snout fluctuations of the mountain glacier, which can be modeled for the different kind of climatic regime. Main objective of this book is to analyse impact of climate change on the dynamics of the glaciers for the last 30 years. Based on the satellite images, the glacial boundaries were visualized and classified into various classes based on the Normalized Difference Snow Index algorithms for the last 30 years. Climatic data from various sources are used.

This book is concerned with the distribution of surficial sediment and variation of water quality parameters under major influences of wind forcing and major rivers inflows in Lake Abaya, the largest Ethiopian Rift Valley Lake. Spatial and temporal variability of physical parameters are presented and the interrelationships between variables are discussed. The results were interpreted in terms of the direction and magnitude of wind forcing, nature of sediment distribution, bathymetry, and major inflow that determine possible pattern and strength of circulation. The observed spatial and temporal variability of physical variables allowed estimating general circulation pattern.

····· lezzter Preis 71.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Global Circulation Models (GCMs) are a major tool used for climate change projections under different emission scenarios. However, for assessing the hydrological impacts of climate change at watershed scale, GCM outputs cannot be used directly owing to the mismatch in spatial resolution between the GCMs and hydrological models. Thus a downscaling scheme (either statistical or dynamical) is employed. For hydrologic impact assessment studies, statistical downscaling is usually preferred over dynamical downscaling and among the variables usually downscaled, precipitation downscaling is more challenging than downscaling of other climatological variables. Therefore, this book is specifically focusing on addressing some of the contemporary issues in statistically downscaling of precipitation at watershed scale. Studies presented in this book make use of two widely used downscaling methods i.e. multiple linear regression and stochastic weather generator. Also, a new downscaling methodology using Gene Expression Programming (GEP) has been proposed. The issues discussed and analyzed in this book will facilitate further research in the area of statistical downscaling for hydrologic studies. ····· 1036125097

Topsoil preservation is extremely important for the geo-environmental reclamation of damaged land due to mining. The issue is the preservation of topsoil in such a manner as to protect its productivity for later use in restoration of mined land. This problem is very much acute and large areas are continually being biologically unproductive every year. Efforts to grow vegetation on overburden dumps and degraded mined lands as a part of biological reclamation are not being successful. This concept reveals a hypothesis that if the biological reclamation is not done within the shelf life period the soil will become biologically sterile and it will be difficult to revive its productivity. This research identifies that the reason behind the biological sterility is the lack of knowledge of shelf life concept. Significance in the field of environmental protection this Monograph are immense and it will help to reclaim the degraded mine land effectively. ····· 10361118375

The main reasons for studying an isostatic model are on one hand the gaps and uncertainties of the seismic models, and, on the other hand, the generous availability of gravity data from global models for the gravimetric-isostatic model. In this study, we present a new gravimetric- isostatic Moho model, called the Vening Meinesz- Moritz (VMM) model. The application of the VMM Moho model could be in estimating the Moho density contrast, studying the dynamics of the mantle or studying the deep-seated inhomogeneities of the Earth`s mantle by gravity field analysis, smoothing the gravity field for downward continuation of the gravity field from the above surface of the Earth (from satellite mission e.g. GOCE) to the mean sea level. ····· 10361119573

The process is of 70-day duration starting from 15 pentads before the monsoon onset over Kerala, when a large convective heat source forms over north Indian Ocean and adjoining West Pacific, which generates a fully developed cross equatorial Low Level Jet stream. During this process there is formation of a warm pool over the Bay of Bengal first followed by a warm pool over the Arabian Sea and active air-sea interaction. We then developed a method for an objective determination of the date of monsoon onset over Kerala for operational use. Using this method we have objectively derived the onset dates for each year of the period 1960 to 2003. The simulation of the positive feedback process between the convection and low-level wind field associated with the summer monsoon Onset is tried next using an atmospheric General Circulation Model.

A devastating health crisis has been unfolded in many parts of the world, due to arsenic enrichment, most likely of natural origin, of groundwater used for drinking and cooking. The mobilization of arsenic from aquifer materials usually occurs under reducing conditions and is microbially mediated. In Bangladesh elevated dissolved As concentrations in groundwater were found mostly in the form of inorganic arsenic as arsenite, detected by several analytical techniques including one that uses a modified colorimetric method. However, time series data suggest that variations in groundwater As concentrations were considerably less in comparison to other redox-sensitive elements such as Fe, Mn and S, suggesting that there are significant decoupling between mobilization of As and Fe, Mn. The results from a series of laboratory microcosm experiments using a representative natural sediment sample collected from Araihazar, Bangladesh raised a major concern that irrespective to Fe, Mn reduction, metal reducers can increase As mobility by converting sedimentary As to a more mobilizable and reduced form. ····· 10361131796

The reasons why some observed catastrophic landslides moved so fast and so far cannot always be explained using standard analyses. Much better understanding is needed to facilitate risk assessment and hazard mitigation measures. In this book, a new model is proposed accounting for temperature rise in the slip zone due to the heat produced by friction, leading to thermoplastic collapse of the soil skeleton and subsequent increase of pore water pressure. This in turn drastically decreases the shear resistance and allows the overlying mass to move downslope ever more freely. The model is validated by back-analysing two case histories, and is then employed in a parametric study to identify the most influential parameters in promoting catastrophic collapse. The results are relevant both for consulting engineers, to better design mitigation measures, and to the research community, by providing a background model through which the interpretation of past landslides can be attempted and more refined landslide models can be developed. ····· 10361136023

The measured spectral optical depths are used for retrieving the aerosol columnar size distribution, characterize and parameterize the spatial gradients, and examine their inter-annual variability. The study demonstrates the significance of continental proximity, advection by the prevailing winds, and long-range transport by air trajectories from distant source regions in controlling the spatial in-homogeneity in the distribution of aerosols over the Arabian Sea and Tropical Indian Ocean.

One of the main risks that may affect the development projects in the area is the flash flood potential. Consequently, the hydrologic setting was delineated and a flash flood index map was created that shows the areas that may be subjected to flash flood threats. The coastline also was evaluated environmentally in two ways: 1) its susceptibility to sand encroachment due to wind-transported sand and 2) its sensitivity to oil spills.

La identificación de patrones multifractales sobre datos observados en registros pluviográficos, sugieren la estimación de atributos estadísticos no lineales concebidos para tal efecto, como son los espectros multifractales. Estos estadísticos han sido introducidos en procesos de análisis no lineal de series de tiempo, tanto en su estructura como en el interés por preservarlos. No obstante, en años recientes una nueva aproximación ha sido desarrollada para la modelación en geofísica, conocida bajo el nombre de Modelo Fractal Multifractal (FM), que además de apoyarse en medidas multifractales y funciones de interpolación fractal, presenta dos rasgos fundamentales que lo diferencia de otros modelos: i) es de naturaleza determinística, y ii) no pretende sólo preservar algunos estadísticos del observable, sino toda la textura registrada. Las señales así simuladas, pueden ser concebidas como observables en el tiempo y/o en el espacio n-dimensional, y sus texturas evocan la geometría observada en los registros hidrológicos. ····· 1036122018

Su interés se debe a tres razones principales: 1) Esos glaciares constituyen la principal reserva de la que depende el abastecimiento de agua de varias decenas de miles de personas. 2) La localización vulnerable del poblamiento en el fondo de los valles y la amenaza de una fusión repentina del hielo, por causas volcánicas, tectónicas o climáticas, configuran un preocupante escenario de riesgo. 3) La evolución del clima ha quedado registrada en las formas del relieve generadas por las fases de expansión y retroceso de los glaciares. La hipótesis en la que se ha basado la investigación es que el impacto del cambio climático en los glaciares puede evaluarse calculando el desnivel entre una ELA geomorfológica, deducida de su forma, y una ELA climática, que expresa el estado de las condiciones ambientales de las que depende su balance de masa. La ELA (Equilibrium Line Altitude) es la altitud de la línea de equilibrio de los glaciares, que separa su zona de acumulación de su zona de ablación ····· 103612990

für 88.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Se presenta un procedimiento para evaluar de forma cuantitativa el riesgo por deslizamientos teniendo en cuenta la peligrosidad, los elementos expuestos y su vulnerabilidad. El método utiliza los modelos de susceptibilidad obtenidos previamente a partir de las relaciones estadísticas existentes entre los deslizamientos ocurridos en el pasado y una serie de parámetros del terreno relacionados con la inestabilidad. La frecuencia de deslizamientos en el pasado se ha utilizado para estimar frecuencias futuras. También se ha realizado un inventario y cartografía de los elementos afectados por deslizamientos en el pasado, y se han estimado los daños para cada tipo de elemento teniendo en cuenta la magnitud del tipo de deslizamiento analizado. Posteriormente se estimó la vulnerabilidad a partir de la comparación entre pérdidas y valor del elemento afectado. La integración de la peligrosidad, vulnerabilidad y valor del elemento ha permitido obtener modelos de riesgo directo e indirecto por deslizamientos para cada tipo de elemento. El resultado final es un mapa de riesgo donde cada píxel muestra las pérdidas esperables por deslizamientos en los próximos 50 años. ····· 1036121812

El objetivo fundamental de este trabajo de investigación ha consistido en el estudio del comportamiento dinámico de los suelos blandos, particularmente cohesivos, que permita desarrollar su modelización constitutiva. Se pretende integrar dentro de un mismo modelo marco las diferentes tendencias de comportamiento tensión-deformación observadas según los diferentes estados de combinación de tensión estática y cíclica y que permita reproducir adecuadamente la generación de presión intersticial en exceso y el fenómeno de degradación para los suelos blandos. Además, se pretende que la formulación constitutiva planteada sirva para problemas más generales y pueda ser utilizada para aplicaciones prácticas. Ello obliga a dotar de sentido físico claro a los parámetros utilizados que deben poder deducirse de ensayos bien conocidos y a la adecuada implementación numérica del modelo empleado. ····· 1036122284

La metodología contempla los tres peligros naturales más habituales en dicho territorio: inundaciones fluviales, incendios forestales y movimientos de ladera. El peligro de movimientos de ladera es evaluado mediante un modelo cualitativo. El peligro de incendios se obtiene a partir de simulaciones múltiples sobre la base de escenarios y situaciones de peligro. Finalmente, aplicando un modelo hidrometeorológico seguido de uno hidráulico, se calcula el peligro de inundación fluvial. Además, se combinan, de manera ponderada, los mapas derivados de los tres peligros considerados, obteniéndose un mapa de peligro natural múltiple.

Los resultados obtenidos de la presente investigación demuestran que las actuaciones implementadas en la Zona Vulnerable han inducido a una importante disminución del contenido de nitratos. Sin embargo, éstas no han sido suficientes, hasta el momento, para estabilizar el contenido por debajo del límite máximo permitido por la Directiva Europea (50 mgNO3-/L). La presencia del Humedal de Salburua dentro de la Zona Vulnerable ha permitido evidenciar que este singular enclave juega un trascendental papel como atenuador de nitratos.

Su presencia ha facilitado la urbanización de la población, pero el aumento de velocidad, la disposición de más carreteras y la reducción de costes percibidos, han facilitado la dispersión de las actividades y de la población, haciendo que cada vez se viaje más, a mayores distancias y en modos motorizados. El automóvil no sólo cubre las grandes distancias, frecuentemente se utiliza para viajes cortos, que podrían ser realizados en bicicleta, en transporte público e inclusive a pie. En Europa, más del 50% de los viajes en coche cubren distancias inferiores a 8,0 km y de ellos, más de la mitad son inferiores a 3,0 km. Considerando que debe primar el interés general , se requieren estrategias que eviten desequilibrios y sesgos, que promuevan la sostenibilidad y que favorezcan a los grupos en desventaja, principalmente.

für 88.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Se presenta una metodología para aplicar el método euleriano-lagrangiano localizado adjunto (ELLAM) a las ecuaciones de flujo y transporte no lineal en un medio poroso. La aplicación se realiza a la ecuación de advección-difusión-reacción y a la ecuación del flujo del agua en un suelo (ecuación de Richards) en dos dimensiones. La metodología consiste en aplicar previamente una técnica de linealización tipo Taylor-Fréchét. Esta linealización es básicamente una expansión alrededor de valores de la variable dependiente en un paso de tiempo previo, a lo largo de las líneas características. En esta expansión, los términos de segundo orden se desprecian, generándose un operador modificado lineal. Tal estrategia permite obtener una aproximación de segundo orden de precisión en el tiempo, independientemente si se emplea una técnica iterativa o no iterativa. Un análisis de la propagación de propiedades numéricas para la ecuación de transporte lineal, muestra que ELLAM no tiene errores de fase lo cual hace que esta metodología solucione de forma muy precisa problemas fuertemente dominados por advección. ····· 10361137371
