- Abstract
Sustainable water resource development is a process of assessment of various thematic resources for its potentials and problems and generation of developmental plans in conjunction with socio-economic constraints which could be implemented on the ground without endangering eco-system. It is very essential to understand various elements of surface and subsurface watershed system and their interrelationship for ecological planning. Barsi watershed in Sholapur district, Maharashtra, India is falling in Basaltic terrain with actuate drinking water scarcity and most of the villages in the watershed are under tanker-fed drinking water supply system. A systematic study has been carried out in the watershed using satellite and collateral data. IRS LISS III satellite data was interpreted in conjunction with collateral data and generated maps of lithology, geomorphology, lineaments, land use-land cover, drainage and water bodies, depth to hard rock and depth to ground water level. A systematic geophysical survey (Vertical Electrical Soundings (VEF)) was carried out at 2 km grid pattern up to the depth of 250 m. Apparent resistivity have been calculated and resistivity contour maps have been prepared for electrode separation of 20m, 40m and below 60m. Resistivity survey data was interpreted and true resistivity maps have been generated for 20m, 45m and below 60m depth respectively in GIS environment. The interpolation of these true resistivity in the above depths as continuous surface indicated low and high resistivity over which village locations and lineaments have been draped. The area indicating less than 40 ohm-m resistivity is considered as potential areas. GIS model has been developed using the maps derived from satellite data, collateral data and geophysical data and carried out the analyzed for identification of ground water source in the watershed. The geophysical data integration with satellite derived maps in the GIS environment provided excellent results. In areas where low resistivity along with good hydrogeomorphological condition and lineaments, were demarcated for construction of bore wells in the watershed. Government of Maharashtra has taken up the implementation activities through Public Health Engineering Department and Ground Water Survey and Development Agency, Maharashtra and the results were encouraging.
