阿曼内志位于世界上最干旱的环境之一。该地区的地下水存在于 Hadhramaut 群的四个不同含水层 A 至 D 中，主要由不同类型的石灰岩和白云石组成。地下水的质量主要由钠、钙、镁、硫酸盐和氯离子等离子组成，但四个含水层的水化学特征各不相同。独立含水层内的矿化沿着地下水流方向从南向北-东北方向增加，直至内志东北地区 D 含水层中的高盐水氯化钠水。对氢和氧进行环境同位素分析，以监测地下水动态并评估地下水进入内志含水层的补给条件。结果表明，迄今为止，该地区一直在对这些含水层进行早期补给以及持续补给。通过山脉 (Jabal) 地区和山脉北侧含水层 D 中的水同位素检测到现代和近现代水域的混合。此外，δ2H和δ18O变化表明，含水层A、B和C被假设为通过断层和裂缝连接，并且含水层之间可能发生相互作用。低氚浓度支持补给区的混合假设。对地下水开发的了解是佐法尔地区水资源可持续利用的重要因素。
The Najd, Oman, is located in one of the most arid environments in the world. The groundwater in this region is occurring in four different aquifers A to D of the Hadhramaut Group consisting mainly of different types of limestone and dolomite. The quality of the groundwater is dominated by the major ions sodium, calcium, magnesium, sulphate, and chloride, but the hydrochemical character is varying among the four aquifers. Mineralization within the separate aquifers increases along the groundwater flow direction from south to north-northeast up to high saline sodium-chloride water in aquifer D in the northeast area of the Najd. Environmental isotope analyses of hydrogen and oxygen were conducted to monitor the groundwater dynamics and to evaluate the recharge conditions of groundwater into the Najd aquifers. Results suggest an earlier recharge into these aquifers as well as ongoing recharge takes place in the region down to present day. Mixing of modern and submodern waters was detected by water isotopes in aquifer D in the mountain chain (Jabal) area and along the northern side of the mountain range. In addition, δ2H and δ18O variations suggest that aquifers A, B, and C are assumed to be connected by faults and fractures, and interaction between the aquifers may occur. Low tritium concentrations support the mixing assumption in the recharge area. The knowledge about the groundwater development is an important factor for the sustainable use of water resources in the Dhofar region.
