Studies of groundwater exploration in Chamarajanagar taluk, using electrical resistivity techniques, Chamarajanagar district, karnataka, south India

摘要

The geophysical methods has been used for a number of applications particularly groundwater potentialudzone. There are four important techniques like gravity, magnetic, seismic, and geoelectrical prospectingudmethods are available. Electrical resistivity (Geoelectrical) methods are the most popular among them andudits highest resolving power and economical viability. Electrical resistivity techniques to investigate theuddifferent lithological formations, bed rock dispositions, the depth to water table or zone of saturatedudformations, thickness of weathered zones, detection of fissures, fractures, fault zones, establishment ofudtheir depths, thickness and lateral extent of aquifers, groundwater flow directions, valley fills, depth toudbasement in hard rocks, fresh and salt water intrusions, groundwater prospective zones, for locating oreuddeposits and archaeological studies. In this area, electrical resistivity method has been worked to analyseudgeoelectrical parameter identification.
