GIS Based for Identification Of Potential Ground Water Recharge Zones In Urban Area - Case Study From A Pune City

Abstract

Ground water is the major source of water in Pune city. Shivajinagar area in Pune city is densely populated and hence creates remarkable burden on the quality and quantity of the groundwater resources. This study focuses on the recharge of the natural resources for sustainable development. With the help of GIS techniques, we create various thematic maps like Geology map, Rainfall map, drainage map, drainage density map, slope map, soil map, land use land cover map. By using weighted overlay analysis for finding out the ground water recharge zone. Final output has been classified into four different zones namely very low, low, medium and high zones.
