Subsurface Alluvial Stratigraphy for Artificial Recharge of Ground Water using Geoelectrical Technique around Southwestern Part of Varanasi District, U.P., India
G. S. Yadav, S. K. Singh
Abstract: Eighty-four geoelectrical soundings (GS) were carried out with maximum current electrode spacing of 1200 m using Schlumberger array for the study of subsurface alluvial stratigraphy for ground water recharge around southwestern part of Varanasi District, U. P. , India. The GS data were interpreted using partial curve matching and Automatic Iterative Method of Resistivity Sounding Interpretation (AIMRESI) techniques. Based on the geoelectrical parameters obtained through the interpretation of sounding data and lithological informations available through boreholes, five vertical geoelectrical cross-sections and seven horizontal geoelectrical cross-sections (slicing) at a specific depth levels have been prepared which clearly show the picture of lithological variation in the subsurface. The entire area is comprised of older and newer alluvium with different grades of sand, silt and clay. The occurrence of ground water has been identified in the sandy formations. The surface condition of the area under study reveals that the artificial recharge can be done by various means to fulfill the future demands.
