Abstract
Numerical modelling of the two main aquifers in Kuwait—the Kuwait Group and Dammam Limestone aquifers—was carried out. Two different well designs were represented in the model: wells completed in the Dammam Limestone aquifer and dual completion wells in both aquifers. The results of the modelling suggested that (i) most of the decline in potentiometric heads will take place in the central and northern part of the study area, (ii) the direction of vertical leakage, which was upward initially, will change to a downward direction (from the Kuwait Group to Dammam Limestone) and (Hi) the flow direction may change in the eastern part of the study area from north to north‐east.
