Digital polygon dataset of rainfall erosivity factor (R) of Koshi basin. The dataset is created using rainstorms of Nepal, India and China from world climate precipitation data. R-factor is computed as the average annual sum of the erosivity of the individual rainstorms, which is calculated as the product of total storm energy and maximum 30-min intensity. R-factor was evaluated from world climate precipitation data with equation (Renard and Freimund, 1994): R = 0.0483*P1.610 where P= annual precipitation (mm).
