Abstract
In this article, GIS, remote sensing (RS) and fuzzy AHP are used to develop a methodology to delineate the groundwater potential zones. GIS-RS technique is used to prepare the different thematic maps that influence the groundwater potentiality. Fuzzy AHP method is used to assign weights and fuzzy ratings to different thematic layers and their attributes classes, respectively. After assigning the weight and rating, Groundwater potential index is calculated by multiplying each thematic layer weights to its attribute class and adding all of them. Thus, the calculated groundwater potential index (GWPI) is used to classify the different groundwater potential zones. The groundwater in the study area is classified into five different classes such as very low (0.51% of total area), low (13.58%), moderate (61.25%), high (23.42%) and very high (1.24%). The delineated groundwater potential zone map is verified using the well depth data, obtained from the central groundwater board (CGWB), India.
