Determination of soil erosion risk with change in land use/land cover is significantly important for its ecological, social and economic impacts. Soil erosion in study area depends on both environmental and anthropogenic factors. To measure such factors, revised universal soil loss equation (RUSLE) model in ArcGIS 10.3 has been employed in the study area. In this study, potential soil erosion risk (RUSLEpotential) determined by environmental factors i.e. rainfall erosivity factor (R), soil erodibility factor (K) and slope length and slope steepness factor (LS) has been calculated. Land use/land cover factor (C) for 1990, 2000, 2010 and 2015 has been computed to measure its change with time. Soil erosion control factor (P) has been computed. Combining RUSLEpotential with C factor and P factor resulted in actual soil erosion risk (RUSLEactual) for four different years.
