Soil Loss Estimation on the Upper Catchment Area of Subarnarekha River : A Geoinformatics Application

The application of RS and GIS techniques provide soil loss estimates based on different parameters. Revised Universal Soil Loss Equation (RUSLE) model is used to determine soil loss estimation. Parameters, namely the rainfall and runoff factor (R), soil erodibility factor (K), slope length and steepness factor (LS), crop management factor (C) and conservation practice factor (P), are the mandatory inputs to the RUSLE. This experiential study was carried out on the upper part of the Subarnarekha River Basin in the South-Eastern part of the Chotanagpur Plateau, India.
