The impact of hydrogeological setting on the protection of coastal groundwater aquifers, El Dabaa, Northwestern Coast, Egypt
U. A. Abu Risha ,N. Sturchio
El Dabaa is located on the Northwestern Coast of Egypt. The main aquifers at El Dabaa are the Middle Miocene fractured limestone and the Pleistocene oolitic limestone. The hydrogeologic setting of these aquifers exposes them to various vulnerability degrees of contamination and salinisation. Seawater intrusion (SWI) and groundwater overpumping represent the main threats of the studied aquifers. This paper aims to provide practical solutions to protect the studied aquifers such as rainwater harvesting, artificial groundwater recharge, and the safe pumping of groundwater. Using the geographic information system (GIS), the sites suitable for implementing these measures were determined.
