Short summary
Soil erosion susceptibility analysis was based on rainfall, Land use, slope and soil erodibility factor. GIS was used to produce the basin susceptibility to soil erosion using weight index of each factors. The results revealed that 106.66 km2 (25.70 %) and 164.80 km2 (39.7 %) of the basin have high and very high susceptibility to soil erosion. The over 50 % high susceptibility of catchment area has negative implications on ecosystem services of the s stream.
