The Middle East and North Africa (MENA) region is the most water-scarce region with only two percent of the global average annual rainfall, hence underground aquifers are the major source of water. The need to improve water productivity and increase aquifer storage and recovery (ASR) is driving the efforts for this acceleration of aquifer storage and recovery project. The objective was to model runoff in the study area using multi-source satellite data and identify regions of runoff retention and recharge. Daily runoff is simulated using a saturation excess principle with the VegET model (Senay 2008). It is a spatially explicit (500m grid cell), one-dimensional root-zone water balance model that is driven by precipitation,...

The U.S. Geological Survey (USGS), in cooperation with the U.S. Agency for International Development, Arab Water Council, Hydrology.NL, National Center for Research and Development (Jordan), and American University of Beirut, completed a project for acceleration of aquifer storage and recovery in the Middle East and North Africa (MENA) region. The MENA region is globally the most water-scarce region with only two percent of the global average annual rainfall. Unsustainable groundwater withdrawals have caused groundwater levels to decline. Groundwater quality has also degraded due to seawater intrusion in coastal areas and infiltration of incompletely treated wastewaters. Managed aquifer recharge (MAR) is an established...
