The management of groundwater resources is crucial in arid and semi-arid regions such as Al-Lith Basin, and therefore, the identification of suitable areas for groundwater recharge is important in solving the problem of water scarcity and ensuring the long-term sustainability of aquifers. In this study, the Analytic Hierarchy Process (AHP) technique, in conjunction with GIS, was applied to locate potential zones for groundwater recharge in the Al-Lith basin. The research methodology includes collecting the essential data, including lineament density, slope, rainfall, drainage density, LU/LC, soil, elevation, and TWI. AHP is used to assign relative weights to different qualities, considering their significance in influencing groundwater recharge. The ArcGIS was employed to process and analyze the weighted layers, which resulted in the creation of a comprehensive map illustrating the potential for groundwater recharge. The study results suggested that the Al-Lith Subbasin has several zones that exhibit different levels of groundwater recharge capability. The results obtained from this study indicated that 12.83% of the basin area has significant groundwater recharge potential zones (GWPZ), ranging from high to very high levels. The groundwater recharge potential zones in the basin are categorized as very poor to poor, covering 19.4% of the area, while the moderate groundwater recharge potential zones represent 67.77% of the basin area. The groundwater protection zones were validated using 19 wells distributed across the basin. The validation findings indicate there is an overlap between the GWPZ classes and the wells in the specified location. Overall, the findings of this study can enhance groundwater resource management and inform policy development for targeted interventions aimed at enhancing groundwater recharge.

地下水资源管理对于Al-Lith盆地等干旱半干旱地区至关重要，因此，确定合适的地下水补给区域对于解决水资源短缺问题和确保含水层的长期可持续性具有重要意义。 。在本研究中，层次分析法 (AHP) 技术与 GIS 相结合，用于定位 Al-Lith 盆地地下水补给的潜在区域。研究方法包括收集基本数据，包括线状密度、坡度、降雨量、排水密度、LU/LC、土壤、高程和 TWI。考虑到不同质量对地下水补给的影响的重要性，层次分析法用于为不同质量分配相对权重。 ArcGIS 用于处理和分析加权图层，从而创建了一张说明地下水补给潜力的综合地图。研究结果表明，Al-Lith 子盆地有几个区域，表现出不同程度的地下水补给能力。研究结果表明，12.83%的流域面积具有显着的地下水补给潜力区（GWPZ），范围从高到极高。流域内地下水补给潜力区为极差至较差，占流域面积的19.4%，中等地下水补给潜力区占流域面积的67.77%。地下水保护区通过分布在流域内的 19 口井进行了验证。验证结果表明 GWPZ 类别与指定位置的井之间存在重叠。总体而言，本研究的结果可以加强地下水资源管理，并为旨在加强地下水补给的有针对性的干预措施的政策制定提供信息。
