Abstract

With the increase in water consumption and climatic variation, hundreds of spring fed watersheds is at a great threat. Due to decline of discharge in conventional water resources crop land has also shrunken which has affected the economy of the region to a great extent. Underground water is present in the form of porous aquifer and springs in hilly and mountainous regions. Due to lack of maintenance and over exploitation many conventional water sources are at the verge of extinction. In this study, GIS- based weighted sum analysis approach was used to identify sites of water potential zones which can be used for both water extraction and rejuvenation of these conventional water sources. GIS based tools can be used for studying of relief and structural aspects of basin. Different factors were quantified and the influence of each factor over is judged. Results show that 21% of area lies under good recharge potential while 79% of the area lies under poor groundwater potential region. Areas with good to excellent recharge potential may be considered for augmentation measures to sustain its specific yield in the future.
