Abstract
This study aims to investigate the soil erosion from selected watershed from Dehradun area having hilly terrain and human’s development activities The remote sensing based model was decided to perform the estimations and assessment of soil eroded from watershed. The Nun river watershed was selected for study. From the estimated quantity of soil eroded we can predict the risk due degraded soil in terms of decreasing crop productivity. The present study assists to decide the optimum land use for specific purpose at the Nun watershed in Deharadun, Uttarakhand. The major objective of the study is to assess the soil erosion risk in the study area.
