Geohydrological investigations were carried out in Kandivalasa river sub basin - a typical Khondalitic terrain near Cheepurupalli town of Vizianagaram district, Andhra Pradesh, India by collecting groundwater levels and conducting fourteen pumping tests during the years 2013–2015. Groundwater levels were measured during pre-monsoon and post-monsoon seasons at forty one locations covering the entire basin. Contour maps were drawn and it is found that there is 10 m depletion of groundwater levels as a whole in the basin for the past 21 years. However, there were pockets of more groundwater depletion in view of the high density of wells at some places. Lower Transmissivity values are observed where differences of depth to water levels between pre and post monsoon seasons are high. Groundwater potential areas are identified with less fluctuation of water table. Lower Storage Coefficient values are found where the kaolinisation is more predominant at the main Kandivalasa river. 2D resistivity imaging has also revealed that the kaolinisation is increasing towards the stream which is responsible for reduction of Storage Coefficient all along the main stream. Based on Transmissivity distribution, eastern part of the study area is identified as high groundwater potential zone while most of the western side of the basin is having less groundwater potential zone.
