Watershed is a region bounded peripherally by a divide and draining to a particular water body. Each watershed varies in shape, size and its characteristics. Morphometric analysis is helpful in understanding and comparing the features within watershed. Two watersheds are considered for the present study. First watershed is a part of Arkavathi river of Cauvery basin and the second watershed is the part of Ponniyar river of South Pennar basin. Both watersheds having a common divide. SRTM DEM is used and Arc GIS is a tool for the study. The 1st and 2nd watersheds are having areas 857.9 km2 and 1718.49km2 and perimeters 142.39 km and 224.47 km respectively. The highest stream order is 7 for both watersheds and the drainages form dendritic pattern. Linear, areal and relief aspects of the watersheds are found out. Both the watersheds are having coarse texture based on the drainage density. The basin is more elongated and having low stream frequency. Hypsometric analysis is a useful tool to assess the erosion status of the watershed. From the hypsometric curve and hypsometric integral, it is observed that the watershed is having an equilibrium or mature stage of erosion.
