<p>Groundwater assessment and management are crucial for all countries, particularly in semi-arid and arid region. Less precipitation, high temperature and over-extraction of groundwater lead to intrusion of saline water, which imposes significant stress on existing groundwater resources. The present study assesses the groundwater potential in the sub-watershed of Wadi Al Maawil, Barka, Oman, using Analytical Hierarchy Process techniques in conjunction with Geographical Information System and Remote Sensing. Different thematic maps, such as slope, geomorphology, geology, soil type, drainage density, topographic roughness, topographic wetness, topographic position index, and Land Use Land Cover, have been overlayed to assess the groundwater availability in ArcGIS platform. Almost 69% of the study area consists of Torriorthents- Gysiorthids favors groundwater infiltration. Nearly 98.3% of geomorphological features and 58.4% of geological features comprises of allluviated pediments and alluvial deposits respectively. These features have developed as a result of the presence of dense streams in the study region which plays a significant role in enhancing the groundwater availability in this arid region. The analysis shows 55% of the study region with a moderate potential, 44% as low potential zones. The moderate potential zone identified in the southern part is in alignment with the existing high groundwater level of 10 to 16&#xa0;m MSL in the observation wells. In the northern zone, the discontinuity of streams originated from the southern part combined with increasing slope in the northern region shows low groundwater potential. Findings may be beneficial for policymakers to frame policies related to groundwater recharge and extraction.</p>
