GIS is a powerful tools in analysing the multiple thematic maps at a time. GIS analysis is carried out in the present study to locate favorable groundwater potential zones. To do this subsurface investigation and its interpretation were carried out through geophysical survey. Forty seven vertical electrical soundings (VES) survey were carried out in the study area. The field data were interpreted by curve matching techniques and RESIST software is used to determine the resistivity and thickness of the different layers. By using conventional GIS method, the spatial distribution maps for weathered zone resistivity and its thickness were prepared. Integration of the said themes was done it in GIS. The out put combinations are 4 of Excellent, Very good, Good and Medium groundwater potential zones were derived, and it is designated as output map-1 (groundwater potential zone map). This map was superposed over groundwater fluctuation map. The derived final result map designated as suitable sites for artificial recharge area. From the final out put area as Excellent, Very good, Good and Medium zones were recommended of this locations suitable sites for artificial recharge structures will be constructed. Other aquifer properties, coefficient of anisotropy varies from 1.02 to 2.40 and longitudinal conductance varies from 0.07 to 0.5 mhos. These values indicate the hardness and compaction of rocks. It is evidenced by low permeability and porosity of the study area.
