#sub-watershed

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.
