The paper describes step by step watershed and stream network delineation based on digital elevation models using the Hydrology tools in ArcGIS and online services for Hydrology and Hydrologic data. The 30-meter resolution SRTM image of Himachal Pradesh was downloaded from open topology website. This was further processed in QGIS and ArcGIS 10.3 software. The different hydrological processes and data management tools were used like, fill, Flow direction; flow accumulation, map algebra, stream orders, stream feature and stream dissolve in order to get the final map of Mandi drainage pattern.
