Delineation of Groundwater Potential Zones in Parts of Vaigai River Basin Tamil Nadu, India using Remote Sensing and GIS Technique
Water resource development and management necessarily depends on proper planning, implementation, operation and continuous monitoring. In India, potable water supply to all people in both rural and urban is main unsolvable problem, because of increasing population and availability of less water resources. The study was done in located area around the Theni district using remote sensing and GIS technology. Remote sensing and GIS technology has vital role in water resource studies, and it has to be effectively used to replace, complement and supplement the earth resources with time and cost effective. In this study, digital image processing based interpretation and classication of Landsat ETM FCC imagery were used to identify and extract landform features, and SOI toposheet with 1:50000 scale was used to delineated drainage patterns, aquifers, lineaments, existing water bodies, recharge beds and other water relevant features using visual and digital image interpretation, and ground truth verication, etc. All the spatial and non spatial, statistical information were inputted in to computer installed GIS software to analysis and produce modeling by the GIS functions such as Density, Overlay, and Integration analysis also. Finally to select suitable site ground water potential in the study area.
