As the demand and needs of the population towards water is growing the value of water is felt in all sectors. At the same time, surface water resources are becoming insufficient to fulfill the water demand. So that systematic planning of groundwater improvement using modern technique is fundamental for the proper management and utilization of this precious resource. But still groundwater resources have not yet been properly exploited, keeping this in view, the present study has been undertaken to demarcate the groundwater potential zones in Kanakanala Reservoir Subwatershed, Karnataka by using RS and GIS approach. Thematic maps of geology, geomorphology, soil, slope, Land Use/Land Cover (LULC) and drainage density were used and groundwater potential zones were demarcated by Weighted Index Overlay Analysis (WIOA) in Arc GIS 10.1 software. During overlay analysis the ranking has been given for each individual parameter of each thematic map and weights were assigned according to the influence towards groundwater. Finally, four groundwater potential zones were delineated viz., very good, good, moderate and poor. From the study it was concluded that, demarcation of groundwater potential zones helpful for effective recognition of suitable locations for its extraction and better planning and management.
