Delineation of watersheds is a fundamental hydrological work. Spatial grids called Digital Elevation Models (DEMs) are employed to automatically determine watershed boundaries. The Bewas River has been studied using DEMs. During the watershed mapping process, several interim findings were generated. This study's findings may be applied to Rainfall-Runoff analyses and other in-depth studies on the catchment region. Additionally, it would aid with decisions about the allocation and management of ground and surface water resources. The project also aimed to gather river water chemistry information for future use. Planning has to do with drinking and agriculture. This research might help with river management as a whole, future food prevention, channel alterations, and property loss planning. The results of this study might be used to develop strategies for water treatment and sustainable land use that include regular monitoring.
