Abstract: In the present study, an integrated approach of remote sensing and GIS is used to delineate the groundwater potential regions of Amaravathy river basin, Tamil Nadu, India. The thematic maps were prepared for delineating ground water potential regions, with relevant data of the basin on geomorphology, geology, slope, density of lineament and drainage, soils and land use patterns. The weighted overlay technique in spatial analysis tool of Arc GIS 10.3 was used to obtain and discuss the groundwater potential zones. According to the influence and movement of ground water, all parameters of thematic map were assigned with a ranking. Thirty five percent of the basin area has good groundwater potential, 45 % of the basin area is with moderate groundwater potential and 20 % of the basin area bear low groundwater potential.
