Geo-Hydrological Study of Semiarid Area, Western Maharashtra, India using Geospatial Techniques

The present study was conducted on Yerala river basin situated in Satara and Sangli districts of Western Maharashtra, India. The remote sensing and GIS techniques have been proved to be very efficient in identification geo-hydrological aspects of the study area. The various thematic maps have been generated like Geology, geomorphology, hydro-geomorphology, geo-hydrology, structure, soils and land use/land cover helped in identification of the potential zones for development planning and forecasting. Lineaments and their intersections appear to be potential sites for groundwater. The study shows that the integration of all attributes provide more accurate results in identification of geo-hydrological characteristics.
