Abstract 

The study area is a part of Purna river basin in the Akola districts of Maharashtra, India. The Widrupa river sub-basin covers an area of 553.05 km2. As geologically the study area comprises the alluvium of Purna River and Deccan trap basalt. The drainage pattern of study area is dendritic to sub-dendritic all around, however it shows parallel drainage pattern in northern part. The study area has been sub-divided into 11 sub-watersheds namely Urma, Khairkhed, Chitalwadi, Khandala, Umarawari, Karal, Telhara, Belkhed, Warula, Pathardi, Devla. The prioritization of the sub-watersheds has been done on the basis of morphometric analysis. For the study, stream network along with their order was extracted from in geospatial environment. Various morphometric parameters have been determined for each sub-watershed and assigned rank based on compound value for final ranking of the sub-watersheds. Based on morphometric analysis, the watershed has been classified into three categories as high medium and low in terms of priority for conservation and management of natural resources. The sub watersheds Urma and Devla shows the low priority, Khairkhed, Khandala, Umarsawari, Karal, Telhara, Warula and Pathradi shows the high priority and Chitalwadi and Belkhed shows the medium priority respectively. 

Key words: Purna River Basin, Widrupa River Sub-Basin, Gis, Morphometric Parameters.
