Abstract: The present study is carried out at Dakshinapinakini river basin, Chikkaballapura and Bangalore districts with reference to remote sensing and hydro-geomorphology to evaluate the potential zones of groundwater occurrence. Geologically the area falls in the semi arid region of older Peninsular Gneisses and associated with ancient Supra-Crustal rocks giving an age ranging from 3000 to 3400 m.y. Hydro-geomorphically the area is divided into five geomorphic features such as Residual hills, Pediments, Pediplain, Valley fill and Lateritic uplands. The groundwater occurrence is good in valley fill areas and in the pediplains, it is moderate to good. The residual hills and pediments have poor to moderate groundwater potentiality.
