The study area is a part of Kagna river basin in the Gulburga district of Karnataka, India. Remote sensing and GIS techniques have proved to be efficient tools in drainage delineation and their updation. These updated drainages have been used for the morphometric analysis. The morphometric analysis was carried out through measurement of linear, areal and relief aspects of basins.
