Abstract :

Abstract: The present study focused on scope of groundwater development in the study area. Average dependable rainfall in the study area is 463 mm; which is resulting about 111.53 MCM of runoff. About 580 Water Harvesting Structures (WHS) with storage capacity of 7.77 MCM was constructed. About 1186 locations has been identified to construct new WHS resulting 3.50 MCM of water will be stored. Natural recharge through rainfall is 31.1MCM, by existing WHS about 15.34 MCM, and 3.73 MCM of water going in to sub surface due to proposed new structures. Deep water levels recorded in pre (51.1 meters) and post monsoon (27.1 meter) in Chinagudala, Pulivendula 17.6 meters in pre monsoon and 15.1 meter in post monsoon and Balapanuru (28 meters in pre and 17.2 meter in post monsoon) and shallow water levels recorded in Thonduru Mandal (5.6 meters in pre and 4.6 meter in post monsoon)
