Artificial Recharge Structures for Heggada Devana Kote Taluk in Southern tip of Karnataka, India using Geospatial Tools

Global warming, climate change, deforestation, rise in water demand for industrial uses rather than domestic purposes has posed serious threats to surface and subsurface water resources. Karnataka is one of the agrarian states in India where groundwater dependency showed always high. The present study involved the artificial techniques in groundwater augmentation analysis by modifying surface runoff in GIS environment with AHP (Analytical Hierarchy Process) methods. Important thematic maps are generated using toposheets, satellite data by GIS insights. Suitable sites for Artificial Recharge Structures (ARS) are derived through AHP by assigning specific weightages depending upon features priority.The results enumerate geospatial technology andAHP tools in achieving best suitable sites for ARS.
