Abstract:
Groundwater is an essential and dependable source of water in India for various uses. Groundwater productivity is quite high when compared to surface water, but groundwater resources have yet to be fully utilized. Because groundwater is a hidden resource, a variety of parameters such as geology, lithology, geomorphology, soils, land use/cover, drainage pattern, and lineaments that control the occurrence and movement of groundwater must be considered and analyzed using deductive techniques involving complex processes for mapping groundwater potential zones. Remote sensing (RS) and GIS-based groundwater studies, in conjunction with field investigations, have been discovered to be effective tools for complex groundwater studies. This review paper compares the work of other researchers to highlight RS and GIS technologies and their applications in groundwater potential zone mapping. The current study discovered that the models used to calculate the Ground Water Potential Index (GWPI) differed from one study to the next. Thematic layer selection and weightages are also arbitrary and based on personal judgment. As a result, a standard model for this study is required, which will undoubtedly allow us to develop and manage precious groundwater resources.
