Abstract
A typical khondalitic terrain covering an area of 450 km2 in Chipurupalli taluk of the Vizianagaram District, Andhra Pradesh, India, has been chosen for well planned and systematic investigations for locating potential aquifers in a typical semi-arid region. A methodology has been developed by assigning numerical weights and ratings to hydrogeological and geophysical parameters depending upon their physical and electrical characteristics which led to proposing a groundwater potential index (gwpi). The efficiency of the method is shown by the improvement in the success rate from 64 to 80%. The proposed methodology further serves to identify the relative groundwater potential of different locations within similar hydrogeologic settings.
