Integration of remote sensing data and the geographical information system (GIS) for the exploration of groundwater resources has become a breakthrough in the field of groundwater research, which assists in evaluating, monitoring, and preserving groundwater resources. In the present study area, various groundwater potential zones for the assessment of groundwater availability in Lingala mandal, Kadapa district, Andhra Pradesh has delineated using remote sensing and GIS techniques. Survey of India toposheets and IRS-P6 LISS III satellite imageries are used to prepare various thematic layers viz. drainage, geology, and hydro-geomorphology and land-use & land-cover. Shuttle Radar Topography Mission (SRTM) data is used for preparing DEM and slope. From 1995 to 2016 rainfall data has been analyzed and correlated with groundwater level data. The groundwater potential zones classified into four class i.e., ‘‘good (15.4%), moderate (40.9%), moderate to poor (31.2%) and poor (12.4%) covering an area of 45.69, 121.51, 92.75 and 36.95 respectively. These maps represent hydrogeomorphological aspect, which are essential for planning, development, management and extraction of groundwater. The present information depicted is very useful for planner and local authority in respect of site selection of well types, depth of well, success rate of wells and as well as groundwater development and management.
