Abstract: An endeavour is made in the present study to identify the groundwater potential zones in the Pulang River basin, Cuddapah district based on the Geological and Geo-electrical investigations. The Geomorphological features and lineament patterns are also studied in locating favourable sites for groundwater. The Geoelectrical soundings conducted at hundred locations in the basin area are interpreted by Schlumberger method. These studies helped to understand the subsurface Geology and in identifying the high groundwater potential zones and to locate in turn the favourable sites for good yielding bore wells.
