The study was conducted to assess the groundwater bearing strata by utilization of resistivity survey in selected locations of Medak district in and around Nrayankhed mandal, NW parts of Bhima basin. The main objectives of the study were to assess depth and thickness of groundwater bearing strata and development of relationship between strata properties and resistivity. The studies were carried out covering seven villages (Baddaram, Venkatapuram, Sirgapur, Jamla Thanda, Thurkapalle, Abbenda and Sheligira) based on lithological formations like granite, basalt and inter-trappeans. The standard Schlumberger electrode configuration was adopted with maximum current electrode (AB/2) spacing of 140 m and potential electrode (MN/2) spacing of 10 m and data was recorded using DD-R1. Analysis of data was achieved using IPI2 WIN software having principal of conventional theory of curve matching. Various layers of different depths and thicknesses were identified.
