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, operating on a control volume defined by the root zone (1 m deep) using soil water holding capacity (WHC) to define the size of the ?bucket?, and the Normalized Difference Vegetation Index (NDVI) is used to parameterize daily actual Evapotranspiration (ETa) rates. The datasets included in this Data Release are: daily, and annual precipitation, daily NDVI, daily reference evapotranspiration, daily, monthly, and annual surface runoff, annual actual evapotranspiration, average annual accumulated runoff including the corresponding coefficient of variance, the VegET model Python scripts, and auxiliary data such as vector watershed file and elevation. For detailed description of each dataset please see the individual meta data files.

Regional screening for managed aquifer recharge suitability in Jordan, Lebanon, and surrounding areasThe 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 regi
Managed aquifer recharge suitability—Regional screening and case studies in Jordan and LebanonThe U.S. Geological Survey, at the request of the U.S. Agency for International Development, led a 5-year regional project to develop and apply methods for water availability and suitability mapping for managed aquifer recharge (MAR) in the Middle East and North Africa region. A regional model of surface runoff for the period from 1984 to 2015 was developed to characterize water availability using
