Water is an elixir of the life and groundwater is the main source of drinking, irrigation, and industrial water uses. Occurrence and movement of the groundwater is mainly depending on the hydrogeological characteristics of the rocks. About 80% of the Maharashtra state is occupied by Deccan basalt exhibiting diversity in the groundwater development. In present study, an attempt has been made to do comparative study of Gomai watershed and Amaravati watershed for analyzing the hydrogeological behavior of basalts of Sahyadri Group and Satpura Group of Deccan Traps.
