在约旦西部泽尔卡河流域的一个子流域内完成了水文地质研究。该系统的特点是背斜弯曲，轴向SSW-NNE，并在SSW方向倾伏几度。背斜构造使地下水流转向SSW，而走滑断层使地下水在断层垂直于地下水流线的地方发散，在断层平行于地下水流线的地方会聚。一个直接的关系被发现之间的位置弹簧和地下水流量的类型方面的排放量，其中大弹簧排放位于收敛的地下水流线的区域。在断层不丰富的地区，地下水在含水层中的滞留时间很长，由于矿物溶解，检测到电导率的分区。通过控制地下水流，背斜构造产生了三种成因类型的地下水流系统：（1）以碳酸氢盐型成分为主的碱土碱性水，（2）以碳酸氢盐-硫酸盐为主的碱土碱性水，（3）高碱性成分的碱土碱性水。
A hydrogeological study was completed within a sub-catchment of the Zerka River drainage basin, in western Jordan. The system is characterized by anticlinal bending with an axis trending SSW–NNE and plunging a few degrees in the SSW direction. The anticlinal structure diverts groundwater flow towards the SSW while the strike-slipe faults cause the groundwater to diverge where the fault is perpendicular to the groundwater flow lines, and to converge where the fault is parallel to the groundwater flow lines. A direct relationship was found between the location of springs and the type of groundwater flow with regard to the amount of discharge wherein large spring discharges are located in zones of converging groundwater flow lines. In areas where faults are not abundant, the groundwater retention time in the aquifers is long and a zonation of the electrical conductivity was detected due to mineral dissolution. By controlling groundwater flow, the anticlinal setting produces three genetic groups of groundwater flow systems: (1) alkaline–earth alkaline water which is predominately a bicarbonate-type composition, (2) alkaline–earth alkaline water which is predominately bicarbonate–sulfate, and (3) alkaline–earth alkaline water with a high alkaline component.
