Abstract: The quantitative analysis of morphometric parameters is found to be of immense utility in river basin evaluation, watershed prioritization for soil and water conservation and natural resources management at watershed level. The study area chosen was Kolar Taluk Sub watersheds, Kolar District since it was found in the rocks and granite area of Karnataka state, India. The study area covers an area of 793.20 km2 and comprise of 24 sub watersheds. In the present this study morphometric analysis of Kolar Taluk watershed is carried out at sub watershed level using GIS which is a suitable tool to study the morphological analysis. The watershed is divided into 24 sub watersheds based on topography and drainage pattern. The analysis is carried out through measurement of linear, aerial and relief aspects of watershed. The morphometric parameters are useful in understanding the hydrological processes of the drainage basin.
