Combination of morphometric parameters and land cover for assessment of soil erosion susceptibility using COPRAS model in lavasanat watershed
Soil erosion is one of the major environmental problems worldwide. Morphometric and landcover analysis provides a platform for quick and efficient watershed management In the present study, morphometric parameters have been coupled with land cover classes to assess soil erosion susceptibility of sub-watersheds of lavasanat watershed. The data used in this study included Advanced Space borne T...
متن کاملApplication of USLE Model & GIS in Estimation of Soil Erosion for Tandula Reservoir
Assessment of soil erosion is expensive and intensively long exercise. A number of parametric models have been developed to forecast soil erosion at drainage basins, yet Universal Soil Loss Equation, popularly known as USLE model is most widely used empirical formula for estimating annual soil loss from agricultural basins. With the advance of Remote Sensing technique it becomes possible to mea...
متن کاملMonitoring Soil Erosion Using Land Cover and Tillage Derived from Satellite Imagery
Under the North Sea Agreement, Norway was obliged to reduce the discharge of nutrient salts from agricultural fields by 50% within 1995. Remote sensing from satellites can be used to monitor soil tillage in the areas concerned. An experiment was carried out which shows that it is possible to classify the different agricultural classes with a high degree of accuracy using LANDSAT TM images. Howe...
متن کاملA User Friendly GIS Model for the Estimation of Erosion Risk In Agricultural Land Using the USLE
In the current study, Universal Soil Loss Equation (USLE) was implemented using GIS, to assess erosion risk on agricultural land in the prefecture of Rodopi (Greece). USLE was programmed in ModelBuilder an ArcGIS application that creates, edits, and manages mathematical models. Data processing and analysis of USLE factors was performed in the form of raster layers. The R factor (rainfall-runoff...
متن کاملSoil erosion modelled with USLE and PESERA using QuickBird derived vegetation parameters in an alpine catchment
The focus of soil erosion research in the Alps has been in two categories: (i) on-sitemeasurements, which are rather small scale point measurements on selected plots often constrained to irrigation experiments or (ii) off-site quantification of sediment delivery at the outlet of the catchment. Results of both categories pointed towards the importance of an intact vegetation cover to prevent soi...
