Delineation of Groundwater Potential Zones in Koyna River Watershed, Maharashtra using Remote Sensing and GIS

Abstract

Groundwater is considered as only source which provides water for meeting domestic, industrial and agricultural requirement. Continuous uses of water without any conservation cause lowering of Ground water level and thus living forms are facing many problems now-a-days. In current situation some existing wells getting dried up because of depletion of groundwater table as the natural groundwater recharge is not sufficient for requirements. As a result, the access to resources and their demand allows individuals to pick favorable locations for population increase. As the world’s population grows, so does urbanization and groundwater exploration. As a rising metropolitan region, it is critical to analyze the present groundwater scenario of the Koyna River watershed. This study is simple to do with the use of remote sensing and geographical information systems (GIS) by cost-effectively incorporating factors impacting groundwater potential. We will combine numerous data sets and maps in this study, including satellite imaging, drainage, groundwater level, precipitation, LULC, slope, and its existing geological map. After including the groundwater potential, it was divided into five distinct zones: extremely poor, poor, moderate, good, and very excellent [1].
