The Tapi River alluvium is covered by 30 percent of the total area of Shirpur taluka in which 4 percent Bazada formation present and Deccan trap is covered by 70 percent. In the study area basalt shows alternate layers of weathered, fractured, hard and massive basalt, while alluvium shows alternate layers of sand, silt, yellowish silt and boulders can be observed. The litho types and thickness of the individual layers from the vertical electrical sounding locations were anticipated by referring litho unit suggested by the Inverse slope method. The area under study is facing a major problem of depleting of groundwater level due to various reasons including unpredictable rainfall leading to excessive withdrawal of subsurface water for agricultural and drinking purpose. The overuse of ground water in alluvium area is mainly for cash crops like sugarcane and banana etc. A thick layer of yellow silt affected the lateral and vertical percolation of ground water while in the study area of Deccan basalt heavy rainfall occur in monsoon months and because of this more surface runoff subjected to the less ground water recharge due to undulating topography. The highest elevation of study area is 420 m near Bijasani Mata Temple to the north and lowest elevation is 150 m near Tapi River in south.
