Groundwater resource assessment in Kushavathi watershed, Chickballapur district, Karnataka, India

Abstract

In the present study, an attempt has been made to delineate the groundwater potential zones in the Kushavathi watershed, Chickballapur district, Karnataka. The study has been for targeting groundwater in hard rock terrain by adopting remote sensing and GIS techniques. Information on geomorphology and land use is generated using the remote sensing data. The hydrogeomorphic units like floodplains and valleys have good groundwater potential, and pediplains and pediments have moderate to poor groundwater potential. The structural hills, denudational hills and inselberg are indicated as runoff zones. The weathered and fractured zone constitute the aquifer system in the area
