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,...

This dataset includes 800m resolution long-term average estimates of evapotranspiration (ET), quick-flow runoff, and recharge within a closed water budget over the 2000-2013 time period and annual estimates for the individual years. It also includes other supporting data associated with the publication of these estimation methods in a concurrent journal article. These estimates were developed with new empirical regressions for (1) quick-flow runoff data generated using data points from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1434 gaged watersheds, as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO); and (2) long-term...
