The geo-morphological characteristics are more commonly used for characterization and prioritization of watershed/basin. Morphometric and land cover classes analysis using Remote sensing (RS) and Geographic Information System (GIS) with multi criteria analytical (MCA) is more effective, time saving and accurate technique for prioritization of watershed and helps in identification of suitable sites for conservation measures. Morphometric analysis revealed that SW8 is more susceptible to erosion followed by SW2. The land cover analysis shows that SW6 is more prone to soil erosion. Combined influence of both the parameters revealed that SW8 is more susceptible and SW1 is least susceptible to soil erosion. This study helps in planning various soil and water conservation measure to arrest soil erosion and improve the productivity of the soils.
