Abstract

Swarna watershed is one of the important watersheds of Udupi district situated in Coastal Karnataka, India. In the present study, the morphometric parameters like mean stream length, basin elongation ratio, bifurcation ratio etc. have been evaluated using conventional, remote sensing and geographic information system techniques. The results are tabulated and are discussed in detail. It has been found that majority of the subwatersheds and Swarna basin as a whole, is vulnerable for erosion. The hydrogeological parameters discussed in the paper will play an important role in the selection and location of the water harvesting structures which are site specific.
