Application of Geospatial Technique to Groundwater Potential Mapping in Mahoba District, India

Groundwater is an important entity for the life as well as the ecosystem. This Precious resource is under extreme strain in India due to man-made and natural caused factors. The identification of groundwater potential zones (GWPZs) becoming more crucial due to increased demand of freshwater across the globe. Therefore, this research presents GIS and Remote Sensing (RS) based algorithm to determine the GWPZs of the Mahoba district, India. Total seven influencing factor that affects the potentiality of the research region i.e. lithology (LI), geomorphology (GM), rainfall, slope, land use and land cover (LULC), lineament density and drainage density. The GIS and RS techniques were employed to prepare all the above mentioned thematic maps. First, the GWPZs were generated by overlaying all the thematic layers over each other after assigning the suitable weights through Analytical Hierarchy Process (AHP) technique. The demarcated GWPZs were categorized into various classifications, i.e. “very high," "high," "moderate," "low," and "very low." Thus the acquired GWPZs were verified through well discharge data. Overall the presents approach will provide the very good performance for mapping the GWPZs of the research area.
