Identification of Groundwater Recharge Zones Through Geospatial Analysis

As the population is increasing day by day the demand for groundwater resource is also increasing. Identification of groundwater potential zone in our study area is an essential assignment for sustainable groundwater resource management through geospatial techniques. For conserving, monitoring and evaluating various groundwater-related development plans Remote Sensing (RS) and Geographical Information System (GIS) will do a vital duty in it. Our current research incorporates RS, GIS and Hydrologic parameters for analysing ground water potential zones in the study area (Dr. Lankapalli Bullayya College of Engineering) with a total area is of 40,485.04m2 . LISS-111(Linear Image Self-Scanning Sensor) it is a multispectral sensor which is a part in the Indian remote sensing (IRS). We used LISS-111 data for our land use cover analysis, to generate hydro geomorphological thematic layers to delineate the ground water potential recharge zones. This layers were transformed into raster to analyse and overlaid to identify the recharge zone by weighted overlay method.
