Abstract: Geohydrological investigations are performed to assess the groundwater parameters for locating suitable sites for groundwater exploration and resource management in the main campus of Banaras Hindu University, Varanasi, U.P., India. Nine vertical electrical soundings (VES) using Schlumberger configurations were carried out at selected locations in the main campus of the university. The interpretation of sounding data has been accomplished using both curves matching as well as computer assisted automatic iterative resistivity sounding technique. On basis of interpreted sounding results, four geoelectrical cross sections have been generated along the profiles. The interpretation of data revealed four layers, generally one top thin layer overlying the other three thick layers. Interpreted results are corroborated with the borehole data. The results depict proper geohydrological conditions for existence of good aquifers suggesting continued supply of groundwater in the campus for extended period.
