TAILIEUCHUNG - Delineation of potential groundwater zone using RS and GIS: A review

Water is one of the most essential commodities for mankind and the largest available source of fresh water lays underground. Tremendous increase in the agricultural, industrial and domestic activities in recent years has increased the demand for good quality water to meet the growing needs. Groundwater is mostly preferred to meet this growing demand because of its lower level of contamination and wider distribution. The occurrence of groundwater is a consequence of the interaction of the climatic, geological, hydrological and physiographical factors. The surface hydrological features like topography, geomorphology, drainage, surface water bodies, etc. play important role in groundwater replenishment. Hence, identification and quantization of these features are important in generating groundwater potential model of a particular area. Remote sensing is an excellent tool for hydrologists and geologists in understanding the perplexing problems of groundwater exploration. In recent years, Satellite remote sensing data has been widely used in locating groundwater potential zones. Satellite remote sensing data is not only cost effective, reliable and timely but also meets the essential requirements of data in the geographical Information System (GIS) domain, which are “current, sufficiently accurate, comprehensive and available to a uniform standard”. | Delineation of potential groundwater zone using RS and GIS A review
