Identification of potential groundwater zone by remote sensing and GIS techniques

Abstract

Water as one of the natural resources required for the survival of man, animals and plants. Water distributed unevenly on the earth’s surface and below the earth’s surface. Groundwater is one of the original wellsprings of consumable water. Without groundwater, humanity cannot survive in this world. Without any regulation and conditions the groundwater continuously extracted. Due to the continuous extraction of groundwater can cause undesirable environmental consequences. Palani Taluk, India identification of groundwater potential zone is important to overcome the issue. Various thematic maps are used and proper weight and rank has assigned to them for identifying groundwater potential zone. By Remote sensing and GIS tools, study area was labelled as excellent, moderate, good and poor groundwater potential zone.
