Water is a boon for all living beings over the world and groundwater is considered one of the indispensable natural sources of potable water. It is necessary to assess and predict the groundwater potential to provide insights for decision-makers for proper planning and management of groundwater. The occurrence of groundwater depends on hydrological, ecological, climate, geological, and physiographical criteria. The purpose of the present study is to choose and attribute scores to all various factors that affected groundwater prospects in the Ba river basin. Firstly, the Delphi method was applied in the expert-based survey to choose six parameters that are considered as influencing factors, namely, lineament density, rainfall, slope, land cover, drainage density, and geology. Then, the weights for the various factors were generated using the Analytic Hierarchy Process (AHP) approach which allows the pairwise comparison of criteria influencing the potential areas. The consistency analyses show that the findings were consistent with a previous study. The consistency and sensitivity analyses showed that the obtained results were coherent, providing the weight vector of the achievable criteria that affect the groundwater prospect in the study area. The study reveals that lineament density and slope are criteria affecting the most prominent groundwater occurrence with 35.1% and 20.1%, respectively. However, the influence of other factors (rainfall, land cover, drainage density, and geology) is not visible. These criteria are assigned to the small weights and do not have a significant influence on the groundwater potential. The study results provide baseline information, which needs to be taken into account to control and manage groundwater potentiality.
