Hydro Geo-Physical Investigation of Groundwater

Groundwater is water that exists in the pore spaces and fractures in rocks and sediments beneath the earth¿s surface. The Electrical Resistivity method was used for the hydro-geophysical investigation of groundwater resources in coconut Garden of Horticulture College so as to discover a sustainable source of water, to meet the various requirements of the campus. The main objectives of the present project were to conduct hydro-geophysical investigation of groundwater potential and to obtain aquifer distribution within the study area in order to delineate possible sites for drilling tube wells for irrigation water supply. A special technique called ¿Resistivity Scanning¿ is found to successfully delineate the fractured geometry of formation. This technique will provide an insight into the nature of subsurface formations. Wenner configuration of electrode arrangement is mostly practiced for the resistivity observations. Resistivity observations were taken with vertical electrical sounding (VES).
