Relationship Between Electrical Transverse Resistance and Hydraulic Transmissivity of Phreatic Aquifers in Basalts

An attempt has been made to extend the empirical relationship between geoelectric parameters and hydraulic properties of an aquifer put forth by Kelly (1977) for the phreatic aquifers of Deccan Trap basalts. Results of pumping tests, resistivity surveys and hydrogeochemical analysis from Godavari-Purna basin were utilised. A linear relationship between Transverse Resistance and Transmissivity of phreatic aquifer was obtained. The linear relationship was extended to other similar basaltic areas for validation.
