Résumé
Understanding of the aquifer systems in regional basins of arid zones is extremely important for sustainable development of water resources. The hydrogeology of a regional multi-aquifer system in the Eastern Province of Saudi Arabia, a major part of the Arabian Peninsula is described. The Umm Er Radhuma aquifer and the Dammam aquifer are the two major aquifers in the study area. They are separated by the intervening Rus aquitard. The structure and lithology of the host formations mainly control hydraulic properties and hydrochemistry of these aquifers. Recharge to these aquifers is very limited. Accuracy of a three-dimensional simulation model including the Umm Er Radhuma and the Dammam aquifers, and the Rus aquitard was evaluated in terms of water levels and flows. Specific yield sensitivity indicated the storage depletion of the outcrop areas. Three different alternative development schemes were analyzed . Continuation of the existing trends of abstraction or increases in major agricultural activity will increase the total abstractions by three to four times causing high drawdowns and dewatering the Dammam aquifer and significant declines in the Umm Er Radhuma aquifer. Adoption of conservation measures with 30% reduction in abstractions would reduce the drawdowns and protect the aquifer system from over exploitation.
