Delineation of groundwater prospects zones in and around Kadiri, Anathapur District, Andhra Pradesh, India

Delineation of groundwater prospects zones have been carried out in and around Kadiri, Anantapure district, Andhrapradesh by using IRS P6 LISS 111 Geocoded FCC data in conjunction with Survey of India toposheet (1:50000 scale) and field inputs were used for thematic mapping. Important geomorphic units identified through visual interpretation of FCC include residual hills, denudational hills, dissected pediments, structural hills, linear ridges, pediplain, alluvium and colluviums. In addition, lineaments were mapped since they act as conduits for groundwater recharge. Majority of lineaments NW-SE, E-W, and NE-SW along with a subordinate N-S set have been recognized. Based on hydrogeomorphological, geological and lineament mapping the study area has qualitatively been categorized into four groundwater prospects zones, viz, high, medium, low and poor. The study reveals that 12.57% of area has high groundwater prospects, 6.45% area with medium 51.48% of the area low and 29.47% area poor groundwater prospects.
