GIS Based Identification of Groundwater Recharging Potential Zones

The groundwater (GW) constitutes one part of the earth ¿s water circulatory system. GW is attracting an ever-increasing interest due to the scarcity of good quality subsurface water and growing need of water for domestic, agricultural, and industrial uses. The concept of integrated Remote sensing and GIS has proved to be an effective tool for integrating watershed management and GW recharging. The problem of the present study is a representative case of overexploitation of GW resources, leading to the continuous exhaustion of the grained as well as the GW aquifers. The integrated use of geospatial and MCDM techniques is an efficient tool for assessing GW recharge, based on which suitable locations for GW withdrawal could be identified. The methodology has been designed by integration of important indicators of GW like geology, geomorphology, lineament, slope, drainage density for exploration of groundwater recharge zone at the watershed scale. The purpose of this book is to provide planners and engineers with practical information to assess the potential for application of artificial groundwater recharge schemes in water supply programs or projects.
