Abstract: Water carry nutrients to areas all around the earth. They play a most important part in the water cycle, acting as drainage channels for surface water. Rivers provide good habitat and food for many of the earth’s organisms. The purpose of this study is to delineate the watersheds basin in the Karaikal district from Bhuvan and United States Geological Survey (USGS) website. Digital Elevation Model is the main data source for extracting hydrology data in ArcGIS. Model Builder was the key for creation of Flow Accumulation, Stream segment, pour point and contour has been prepared using surface tool in ArcGIS software. Watershed delineation map is obtained by integration of Flow Accumulation, Stream segment and Pour point. Watershed analysis provides catchment boundaries but also hydrological parameters useful for management programs.
