In the present study, soil erosion susceptibility analysis has been carried out in the Dikrong watershed, predominantly located in the Arunachal Himalayas, applying the Weighted Sum Analysis (WSA) technique on some important morphometric parameters. Based on this approach, prioritization of the sub-watersheds has been determined by assigning weightages, derived from the correlation matrix, to the respective parameters and, accordingly, the sub-watersheds have been categorized into three priority levels viz., high, moderate, and low to very low. It has been ascertained that sub-watersheds Niorch, Chimpu, and Pang are high susceptible zones requiring urgent and efficient planning and management for better conservation.
