Abstract: Vertical Electrical Sounding (VES) study was conducted for 20 points (four sites having five points each) in Damodar River Basin in West Bengal State in India employing Schlumberger Array electrode configuration along with Borehole Litholog. Depth of interpretation was found to be around 25 m at each VES point for the input survey distance of 50 m. From the interpreted resistivity values it can be commented that the points where the soundings were carried out normally had dry sand having variation in moisture content up to a depth of approximately 5 m. But in the case of Site 2 the sand content of the top layer was found to be drier and had bigger gravel and rock particle mixed with sand. From the interpreted results it can be inferred that all the sounding points except three have the existence of a layer saturated with fresh water. Depth to bedrock from VES study was correlated with depth to bedrock from Borehole Lithologs. Therefore this study is significant for both reading public and future workers as the equation developed using the constants and variables can be used to predict depth to Basement Rock in the Terrain prevailing in that region.
