Electrical resistivity studies at 56 locations in an around Muddanur area has been carried out. The main lithological units in the study area are quartzites, shale and limestones. The data were interpreted with the help of master curves and auxiliary point charts. The study reveals that the weathered and fractured portions in shale and limestone that occur in the central portion of the study area constitutes the productive water bearing zones classified as good groundwater potential zones.

Remote sensing is a direct adjunct to field, recently playing an important role in the study and assess the natural resource in any part of the world.
