Present research paper is an attempt to analysis of the stream ordering in sub-watershed in the Gori Ganga watershed Kumaun Himalaya, Uttarakhand (India) where Gori Ganga watershed has 2191.63 km2 area. For the study of detect stream order and delineation sub-watersheds used of Remote Sensing (RS) data Cartosat-1 of 2008. Using pour point technique for the Gori Ganga watershed is divisible in to 9 sub-watersheds these are varies between 83.97 km2 (viz., Baram sub-watershed) and 794.97 km2 (viz., Gori Ganga sub-watershed). Sub-watersheds of Gori Ganga watershed has total 2299 first order streams which contribute 47.37% (234 km), 1302 second order streams which contribute 26.11% (129 km), 430 third order streams which contribute 8.71% (43 km) and 893 fourth order streams which contribute 17.81% (88 km). Where Gori Ganga sub-watershed has the longest stream about 170 km (34.41%) and Raunits Gad sub-watershed has the smallest stream about 18 km (3.64%). Present study describes details of stream ordering pattern in 9 sub-watersheds based on remote sensing and GIS. A brief account of these results it’s discussed in the following paragraphs.
