Watersheds are natural hydrological entities that cover a specific aerial expanse of land surface from which the rainfall runoff flows to a defined drain, channel, stream or river at any particular point. In the last two decades, watershed management has gained the top most priority in water resources sector necessitating delineation of watersheds upto mini watershed level in order to take up watershed development and management programmes. Prerequisite for watershed management is knowledge of watershed characteristics like slope, relief, aerial extent and drainage networks. Geographic Information systems (GIS) with Digital Elevation model (DEM) can be used for the computation of various watershed characteristics effectively and efficiently than manual computation which is tedious and time consuming. Kosi is the main river of Almora district. SRTM (Shuttle Radar Topographic Mission) data of 30 m resolution was used for stream network analysis of Kosi river in Kumaon division. In this study an attempt is made to illustrate watershed and stream network delineation of Kosi river in Almora district based on digital elevation models using the hydrology tool in the ArcGIS Geo-processing toolbox. This study also reveals the relationship between other spatial features.
