Assessment of Groundwater Potential Zones Using Geographic Information System and Analytic Hierarchy Process (AHP) Techniques in Chhoti Kali Sindh Watershed in Ujjain district, Madhya Pradesh, India

Abstract

Geographic information system (GIS) and Analytic Hierarchy Process (AHP) techniques combinedly employed for delineation of groundwater potential zones in the Chhoti Koli Sindh watershed, in the present study thematic layers of geology, geomorphology, lineament, drainage density, landuse have been prepared .DEM generated from the 20 m contour map and a slope maps has been prepared using DEM. These maps integrated is GIS environment and a multi criteria decision making (MCDM) approach in the form of analytical hierarchy process were employed in which the rating and weights for every theme were assigned according to their influence on these themes and groundwater potential zones were obtained using weightages as very high, high, moderate and poor potential zone. The potential zone map also reveals that about 62% of total area comes under high groundwater potential zone category
