A Review of Managed Aquifer Recharge Potential in the Middle East and North Africa Region with Examples from the Kingdom of Saudi Arabia and the United Arab Emirates

Groundwater extraction in most Middle East and North Africa (MENA) countries far exceeds its renewability, which ranges from 6% to 100%. Freshwater resources support food production are very limited this region. Future climate predictions include more consistent longer wet periods with increasing surplus rainfall, will enhance flood flash occurrences the MENA. Demand management of groundwater managed aquifer recharge (MAR, also called replenishment, water banking, artificial recharge, is purposeful aquifers for subsequent recovery or environmental benefits) represent essential strategies overcome challenges associated depletion change impacts. Such would enable development MENA region by minimizing stress placed on these resources, as well reducing deterioration quality. augmentation through dams a common practice different around globe. Most were built even few protection act one way another. However, operating systems mostly dependent natural infiltration accumulated reservoir area, application MAR. This review presents analyses renewability effectiveness potential MAR technology. study indicates that efficiency dam’s between 15 47% clustered lower limit. Efficiency reduced clogging bed fine materials. Therefore, there need improve operation using
