Site selection for artificial recharging of groundwater by application of geoelectrical method - A case study

Abstract

To meet shortage of groundwater, the application of artificial recharge offers a great scope for the and and semi and regions as the water available in time of plenty can be stored in this manner for utilization in times of shortage. The choice of a particular method of recharge is governed by local geology, topography and soil conditions etc. The percolation of water into the zone of saturation is mainly dependant on the nature of lithology and thickness of the alluvial overburden. In this study, an attempt has been made to delineate different lithological conditions by the application of surface geoelectrical method at three different sites in the western part of Iran. The data obtained were interpreted and the results show that lithological mapping by resistivity method is a feasible factor in selection of recharge sites.
