Abstract
The search for new groundwater resource is essential to sustained economic development in arid environment. The purpose of this study was to investigate new water sources using remote sensing and GIS methods. The thematic layers considered in this study area Geology, Geomorphology, Soil, Land use / Land cover, Drainage density, Slope, Lineament density, and Rainfall map were prepared for the study area using the IRS-P6 LISS-IV satellite imagery and conventional data. In addition, soil and drainage maps were digitized from Toposheet maps. The thematic layers were finally integrated using Arc-GIS 10.1 software to yield a groundwater potential zone map of the study area. Thus, five different groundwater potential zones were identified, namely very good, good, moderate, poor and very poor prospects covering an area of 4.97 Km2, 131.26 Km2, 107.81 Km2, 26.76 Km2&10.92 Km2 respectively. This GIS based output result was validated using water level depth data collected from central groundwater board. Finally, it is concluded that the RS and GIS techniques are very efficient and useful for the identification of groundwater potential zones.
