ABSTRACT

Present research paper is an attempt to delineation and classification of the Gori Ganga watershed, Kumaun Himalaya, Uttarakhand (India). The present study watershed and sub-watershed delineation and classification based on remote sensing and GIS techniques, and Cartosat-1 satellite image of 2008. The Gori Ganga watershed is divisible in to 9 sub-watersheds, size of these sub-watershed varies in between 83.97 km2 (viz., Baram sub-watershed) and 794.97 km2 (viz., Gori Ganga sub-watershed). There are total 168 villages situated in 8 sub-watersheds in which those number of villages varies in between 1 (viz., Gori Gad, Lwan Gad and Ralam Gad sub-watershed) and 95 (viz., Gori Ganga sub-watershed). In the entire watershed total number of streams is 17645 and total length of these streams is 8561.62 km.

Key words: DEM, Stream Network, Stream Ordering, Watershed Delineation
