Abstract
Remote sensing and Geographical Information System (GIS) is effective tool for delineating drainage patterns and managing water resources. The study takes into account the Kayadhu watershed in the Hingoli & Parbhani district of Maharashtra. The catchment area of the basin is approximately 2146.1 km2. The Kayadhu River basin has been prioritized to identify erosion susceptibility zones & suggesting the most sensitivity to erosion and also proper soil and water resource management. Prioritization was done using remote sensing and GIS technology based on morphometric parameters and land use analysis. Several parameters that are directly or indirectly related to erodibility have been calculated. The basin analysis of the Kayadhu Watershed basin depicts the region's good potential, which requires integrated and sustainable planning and management. The final prioritization result revealed a common compound value (Cp) for each sub-watershed was calculated by taking the average of the LC and morphometry rankings. The final priority was determined by categorizing the highest and lowest ranges of Cp value into three classes.
