This study may help in future planning for groundwater exploration strategy and development for groundwater resources.Ībdulaziz AM, Hurtado JM, Faid A (2012) Hydrogeological characterization of Gold Valley: an investigation of precipitation recharge in an intermountain basin in the Death Valley region, California, USA. Both the wells are drilled during the month of April and June, 2013, which are productive with a yield varying from 82.14 to 105 l/min. The basement of the hard rock aquifer system is clearly delineated showing very high resistivity with a range from 5000 to ~4 × 10 5 Ohm.m, which is confirmed by drilling at two places. On the other hand, the induced polarization (IP) results reflect marginal chargeability contrast, which indicates groundwater prospect zone.
The interpreted results derived from two-dimensional (2D) inverted resistivity models revealed substantial resistivity contrast between the weathered and massive granite and delineated three groundwater prospects zones, where the degree of weathering of fractured granite decreases with depth. High-resolution electrical resistivity tomography (ERT) and time-domain-induced polarization (TDIP) dataset were collected in a granitic terrain to solve the groundwater problem as people are facing acute shortage of drinking water in the study area. A study was carried out at Choutuppal Telangana, India, under the pivotal research project of societal relevance. Groundwater investigation in a crystalline rock is a crucial task.
