AbstractThe GIS has been found to be an effective tool for delineating the groundwater potential zones. The several studies have been carried out for identification of groundwater potential zones. Nishtha (2009) identified groundwater potential zones and results shows that the area having ‘good’ groundwater potential is about 152.6 km2 which is about 44 per cent of the total study area. The southern and southwestern portion of the study area falls under moderate groundwater potential zone. It encompasses an area of 102 km2 which is 29.5 per cent of the total area. Singhal et al. (2010) delineated aquifers in the piedmont zone of Himalayan foothill region in Pathri Rao watershed and results shows that the the stage of groundwater development in the watershed is 164 per cent indicating critical over-exploitation of groundwater. Preeja et al. (2011) identified groundwater potential zones in Ithikkara River Basin (IRB), Kerala and results shows that the groundwater occurrence is controlled by geology, structures, slope and landforms. Ndatuwong and Yadav (2014) identified the groundwater potential zones in Vindhyan basin of central India and results shows that the integrated map of the area shows different zones of groundwater prospects, viz. very high (0.77% of the area), high (35.57% of the area), moderate (54.53% of the area), while poor and very poor are made up of 9.13% of the area.
