4-Conjuctive use of groundwater and canal water in Basaltic upland area of Maharashtra

Abstract

The paper presents results of hydrogeological studies carried out in two representative river basins of upland Maharashtra. These results are well comparable to other river basins in basaltic upland terrain. The river basins of upland Maharashtra have been divided into three groups which provide knowledge about the riverine sediments from groundwater point of view. The aquifers in the Deccan Trap and riverine sediments yield water from 12 to 400 lit/day and 135 to 1000 Klit/day during summer respectively. Isolated saline tracts are common along the riverine sediments of each group. Geochronology of the area suggest that the Quaternary sediments generally yield saline water. Based on geohydrological studies, suggestions have been made for planning and implementation of conjuctive use programme in river valley projects in basaltic upland area of Maharashtra.
