Abstract
Subsurface water refers to all water that exists naturally beneath the earth's surface. Groundwa-ter is crucial for the formation of ecological niches, sustainability of the ecosystem, and socio-economic development of a region. Groundwater accounts for 34% of the world's freshwater resources. The Kamrup Metropolitan District's rising population places a high demand on natu-ral resources. One of them is groundwater. Unplanned rapid urbanisation accompanied by rising population growth led to significant anthropogenic changes to the environment of the region. Around 70% of the district's population is dependent on groundwater which has led to deple-tion. Therefore, the study of the potential groundwater zone is important to facilitate groundwa-ter recharge through proper management. In GIS-Analytical Hierarchy Process (AHP) helps to evaluate the GWPZ. The study is based on assigning weights to eight interdependent factors that control groundwater potentials such as geomorphology, lineament density, elevation, slope, soil, drainage density, rainfall, and land use/land cover (LULC). These parameters were gener-ated using remote sensing and conventional data. The study reveals that approximately 56% of the total area falls in the 'good' and 'excellent' potential zones. The remaining 44% of the regionfalls in the 'poor' and 'fair' categories.
