Spatial and temporal variability of rainfall erosivity (R-factor) for Vashisthi River basin erosion: Implications for the Revised Universal Soil Loss Equation

A major issue brought on by land degradation, increased agricultural productivity, and other human activities is soil erosion. Planning and conservation efforts within a basin or watershed benefit from an assessment of soil erosion. Soil erosion is primarily influenced by rainfall patterns and land cover, and modeling soil erosion is crucial for assessing the degree of land degradation. Under a variety of circumstances, modeling can offer a quantitative and reliable method for estimating soil erosion and sediment output. In the current work, soil loss in the Konkan region of India of the Vashisthi Basin has been estimated using the Revised Universal Soil Loss Equation (RUSLE), a soil loss model integrated with GIS rainfall data for previous 16 years (2006–2021) referred to analyses study.The RUSLE model, in conjunction with elements such as the Rainfall Erosivity Factor (R), for case study of Vashisthi River Basin (VRB) of Konkan, Maharashtra (India) given results with average value for Chiplun (30978.105 MJ.mm/ha/hr/y), Dapoli (30701.941 MJ.mm/ha/hr/y), Khed (28807.257 MJ.mm/ha/hr/y),Guhagar (24210.344 MJ.mm/ha/hr/y)
