Underground water resources can be identified using many geological, geomorphological, structural and lithological criteria. The Geophysical methods are more useful, indeed, tell us about the exact disposition of the concealed underground water, its quantity and quality. Among the various geophysical techniques, Electrical Resistivity methods are widely used and producing appreciable results. Despite sufficient rainfall, large part of India suffers from water scarcity. Ground water occurs in weathered or semi-weathered/fractured layers in hard-rock areas whose thickness varies, in general, from 5m to 20m. In the present study, an attempt has been made to delineate various subsurface layers and pick out suitable locations for drilling of borewells or construction of open wells for assessment of groundwater availability in Gangaikondan Panchayat (Tirunelveli District, Tamilnadu) which shows various groundwater potential zones.
