Assessment of Groundwater potential zone using remote sensing and GIS, A case study in Nandhiyar sub basin, Tamilnadu, India
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
Groundwater is one of the greatest hidden natural resources of the earth’s crust. It has ubiquitous occurrence. The deformative forces and different earth processes depending upon the nature and composition of the rocks produces characteristic structural, morphological features, which themselves are responsible for the groundwater accumulation, storage and movement, a detailed understanding of all these pathfinders and appreciation of their relative significance in different hydro geological environment is essential in proper planning and management of the groundwater resources. Assessing the groundwater potential zone is particularly important for the safety of water quality and the management of groundwater systems. A case study was conducted in Nandhiyar sub basin to find out the groundwater potential zone. The thematic maps such as geomorphology, geology, soil, drainage, lineament map were prepared in Arc GIS. All the thematic layers were integrated in to Arc GIS 9.3 software to find a groundwater potential zone map of the study area. Thus, three different groundwater potential zones were identified, namely 'Poor', 'Moderate' and 'Good'.
