Abstract: As the demand and needs of the population for water is growing, the value of water is felt in all sectors. Therefore, groundwater resources needed to be mapped properly to exploit. The present study has been taken to delineate and classify the groundwater potential zones of the Bilate River catchment basin using overlay of themes in GIS environment. The consideration of thematic layers in the study are geology, geomorphology, drainage density, lineament density, rainfall, soil, slope and land use/ land cover and groundwater potential zones were delineated by using Weighted Overlay Analysis in Arc GIS 10.1 software. In the thematic overlay analysis, individual parameters is assigned with ranking considering the more or less their influences towards groundwater prospects. The integration of thematic layers finally is done using ArcGIS software to demarcate the groundwater potential zone map. Thus, three groundwater potential zones are categorized viz., good, moderate, and poor.

Keywords: In the Thematic Overlay Analysis, Individual Parameters is Assigned with Ranking Considering the More or Less their Influences Towards Groundwater Prospects.
