Delineation of Groundwater Potential Zones & Application

An integrated survey based on satellite image interpretation corroborated with limited field checks were carried out with a view to delineate the ground water potential in parts of Y.S.R District district, Andhra Pradesh, South India. The interpretation of Remote Sensing data & GIS in conjunction with conventional data and sufficient ground truth information makes it possible to identify and outline various ground features such as geological structures, geomorphic features and their hydrologic characters that may serve as direct or indirect indicators of the presence of ground and surface water. In the present study, a detailed investigation was carried out with an objective of identifying the index of groundwater by using Water Quality Index (WQI) method. Prominent water quality parameters controlling the hydrochemical evolution of aquifer system was studied.
