研究区位于约旦中部,面积约6874公里2。这项研究的重要性在于确定与人口增长、地下水枯竭和灌溉活动有关的不同环境条件。本研究的主要目的是研究过度抽水对死海盆地地下水质量的影响。2011年该盆地的总抽采量为81.1 MCM,安全产量为57 MCM,超抽率为安全产量的142%。采集了180口不同位置的地下水井的500个水样,并对水样的理化性质进行了分析。对分析的水样采用SPSS软件进行聚类分析。结果表明,根据Langguth理论,地下水分为两种类型;第一种类型为碱含量增加和氯化物普遍存在的碱土水。大约90%的地下水样本属于这种类型。 The percentage of earth alkaline ions is higher than that of the bicarbonate. The chemistry of the first type shows the flowing ionic order:Ca+2+2+ andCa+2< HCO3-. The second type was characterized by alkaline water with prevailing chloride. This type represents about 10% of the total water samples in the Dead Sea basin, with ionic ratio as: Ca+2+2+ and (Ca+2 +Mg+2)< (HCO3-+SO4-2). Few samples slightly exceeded the level of chloride (300 mg/l). Three clusters were determined and the whole were classified as very hard based on hardness. According to the USA Salinity Diagram, two clusters were determined, the first and second clusters were classified as high salinity hazard with low sodium hazard (C3-S1) and the third one is classified as very high salinity hazard with low sodium hazard (C4-S1). That means these are not suitable for irrigation purposes.
