Book Synopsis Spatial Techniques for Soil Erosion Estimation by : Rupesh Jayaram Patil
Download or read book Spatial Techniques for Soil Erosion Estimation written by Rupesh Jayaram Patil and published by Springer. This book was released on 2018-02-06 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a novel computation of the topographic LS factor of the USLE model to estimate spatial soil erosion. In developing countries, soil erosion is one of the main concerns as it adversely affects agriculture and reduces food production. Therefore, the author presents a particularly relevant approach, as he demonstrates how the C++ programming allows us to identify important erosion stages like detachment and deposition. He does this by assessing the annual rate of soil erosion from the Shakkar River watershed in India using distributed information and applying RS and GIS techniques. He also discusses different approaches that have been proposed to work out the influence of topography on erosion. Simulated and observed data of sediment loss are compared for the period 1992 to 2006.This book provides an easy-to-understand basic piece of soil erosion and hydrological research and reaches out to young researchers and students at the graduate and undergraduate level as well as applicants of soil erosion models.
Book Synopsis Geospatial Technologies for Land Degradation Assessment and Management by : R. S. Dwivedi
Download or read book Geospatial Technologies for Land Degradation Assessment and Management written by R. S. Dwivedi and published by CRC Press. This book was released on 2018-10-17 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: The constant growth of the world’s population and the decline of the availability of land and soil resources are global concerns for food security. Other concerns are the decrease in productivity and delivery of essential ecosystems services because of the decline of soil quality and health by a range of degradation processes. Key soil properties like soil bulk density, organic carbon concentration, plant available water capacity, infiltration rate, air porosity at field moisture capacity, and nutrient reserves, are crucial properties for soil functionality which refers to the capacity of soil to perform numerous functions. These functions are difficult to measure directly and are estimated through indices of soil quality and soil health. Soil degradation, its extent and severity, can also be estimated by assessing indices of soil quality and health. "Geospatial Technology for Land Degradation Assessment and Management" uses satellite imagery and remote sensing technologies to measure landscape parameters and terrain attributes. Remote sensing and geospatial technologies are important tools in assessing the extent and the severity of land and soil degradation, their temporal changes, and geospatial distribution in a timely and cost-effective manner. The knowledge presented in the book by Dr. R.S. Dwivedi shows how remote sensing data can be utilized for inventorying, assessing, and monitoring affected ecosystems and how this information can be integrated in the models of different local settings. Through many land degradations studies, land managers, researchers, and policymakers will find practical applications of geospatial technologies and future challenges. The information presented is also relevant to advancing the Sustainable Development Goals of the United Nations towards global food security.

Book Synopsis GIS-based Streambank Video Mapping to Determine Erosion Susceptible Areas by : Brett Allen Connell
Download or read book GIS-based Streambank Video Mapping to Determine Erosion Susceptible Areas written by Brett Allen Connell and published by . This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the U.S. Environmental Protection Agency, excess sediment is a significant cause of water quality impairment for rivers (USEPA, 2009). Therefore, determining the areas of river where streambank erosion is the highest should provide valuable information. Considering the amount of funds being spent on river restoration and storm flow retention, there needs to be a more efficient method to document annual conditions, on a watershed scale. Traditional streambank survey methods are limited in total characterized area, time consuming, environmentally intrusive, and expensive. This project describes the development of a Bank Erosion Susceptibility Index (BESI) to map landscape scale, streambank erosion susceptibility. The Streambank Video Mapping System (SVMS) equipped kayak provides georeferenced video footage correlated with Global Positioning Systems (GPS), for Geographic Information Systems (GIS) mapping applications. BESI was then applied to the video with erosion susceptibility scores being displayed within ArcGIS. Parameters being assessed while watching georeferenced video include bank angle, bank height to bankfull ratio, surface protection, and riparian diversity. A 7.7 km reach of the New River (TN) was mapped and determined to be 78% low, 21% moderate, and only 1% high scores of erosion susceptibility. A 7.6 km reach of Beaver Creek was mapped with 81% low, 18% moderate, and 1% high scores of erosion susceptibility. Physical field measurements were compared to video assessment showing an average of -1.4 percent error at 38 sites. Additional analysis showed a 3.5 BESI score standard error value, relating to viewer subjectivity between five people applying the BESI. Through this method, field time, cost, and environmental impact will all be reduced, with the most erosion-susceptible areas being highlighted for further documentation or restoration efforts.

Book Synopsis Assessment of Erosion Vulnerable Area Using Gis and Remote Sensing by : Abebe Mengaw
Download or read book Assessment of Erosion Vulnerable Area Using Gis and Remote Sensing written by Abebe Mengaw and published by LAP Lambert Academic Publishing. This book was released on 2012-06 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation in the form of soil erosion is a serious and continuous environmental problem in different part of the world. Uncontrolled land use, deforestation, land over cultivation, overgrazing and exploitation of biomass for firewood, construction and other household uses due to increasing population ultimately leads to severe soil erosion. This study had integrated GIS, RS and MCE models to assess and map erosion vulnerable areas and RUSLE model to quantify an estimated soil loss in Jabi Tehinan Woreda. Slope gradient, soil type, LULC, rainfall and drainage pattern were used as input model parameters/variables. The data had been collected and analyzed from different land sat imageries, SRTM data, topomaps and point interpolations of primary data. Finally the aggregated effects of all parameters had been analyzed and priority rating of erosion vulnerable area was calculated using weighted overlay techniques.

Available in PDF, EPUB and Kindle. Book excerpt: Degradation of agricultural catchments due to water erosion is a major environmental threat at the global scale, with long-lasting destructive consequences valued at tens of billions of dollars per annum. Eroded soils lead to reduced crop yields and deprived agroecosystem’s functioning through, for example, decreased water holding capacity, poor aeration, scarce microbial activity, and loose soil structure. This can result in reduced carbon sequestration, limited nutrient cycling, contamination of water bodies due to eutrophication, low protection from floods and poor attention restoration—consequences that go far beyond the commonly modelled soil loss and deposition budgets. This book demonstrates, using data from the Harod catchment in northern Israel, how cutting-edge geoinformatics, data science methodologies and soil health indicators can be used to measure, predict, and regulate these major environmental hazards. It shows how these approaches are used to quantify—in time and space—the effect of water erosion not only on the soil layer, soil minerals, and soil loss, but also on the wide-range of services that agricultural ecosystems might supply for the benefit and well-being of humans. The algorithms described in this book play a major role in this paradigm shift and they include, for example, extraction of photogrammetric DEMs from drone's data, advanced drainage structure calculations, fuzzy process-based modelling and spatial topographic threshold computations, multicriteria analyses and expert-based systems development using analytic hierarchal processes, innovative data-mining and machine learning tools, autocorrelation and interpolation of soil health, physically-based soil evolution models, spatial decision support systems and many more.

This book was released on 2012 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intensive use of limited water resources, the growing population rates and the various increasing human activities put high and continuous stresses on these resources. Major problems affecting the water quality of rivers, streams and lakes may arise from inadequately treated sewage, poor land use practices, inadequate controls on the discharges of industrial waste waters, uncontrolled poor agricultural practices, excessive use of fertilizers, and a lack of integrated watershed management. This study explores the impact of these pollution problems and the water quality degradation of irrigated agricultural watersheds. When the watersheds have a complex physical basis of interacting water bodies such as canals, drains and coastal lagoons as in the case of irrigated watersheds in coastal river Deltas, and when these environments are 'data scarce environments', the problems of managing water quality becomes more obvious and the need for reliable solutions becomes an urgent requirement.
