Identification of Groundwater Conditions Using Geoelectrical Resistivity Technique

S. P. Singh and Priyamvada Singh


In the present work an attempt has been made to identify the aquifer zone and subsurface lithology by geoelectrical resistivity method using Shlumberger configuration in parts of Naveda block, Kaushambi, Allahabad, Uttar Pradesh, India. At total 50 placesvertical electrical sounding (VES) was carried out to identify the suitable conditions of groundwater. The interpretation of resistivity data was given in two different ways. The first way of interpretation of data was to get geoelectrical parameters in forms of apparent resistivity and thickness. Secondly these parameters were used to extract the nature of surface geology and extent of aquifer. The interpretation was done with the help of three and two layer master curves and auxiliary point charts. The results revealed that the average depth of aquifer is 63 m and thickness is about 45 m in the study region. Further the bedrock was encountered at approximately 80-90 m. These results must be helpful to water resource managers and policy makers.
