Recharging of groundwater by the geophysical method based on resistivity meter, a case study of Naya Raipur Chhattisgarh

Abstract

To maintain the balance in the water table, artificial recharge is being adopted in many regions. For this, numerous studies have been carried out. In the present study, vertical electric soundings have been carried out in the different locations of surrounding Atal Nagar, Naya Raipur at 09 random sites to understand the nature and extent of the aquifer and to find out the groundwater potential zone for rainwater harvesting sites. The main objective of this study is to identify the possibility of an appropriate recharge structure at a suitable location. From the interpretation of the VES curve, the evaluation of layer parameters has been done depicting the actual depth of aquifers and high yielding fracture zones. The VES curve has been made to interpret the subsurface geological layers which indicate the 3 to 4 subsurface layers having different resistivity and thickness. When this VES data is correlated with the lithology data of the area, the actual groundwater bearing zone and potential zone can be identified.
