Average annual rates of evapotranspiration, quick-flow runoff, and recharge for the CONUS, 2000-2013

Metadata Updated: July 6, 2024

This dataset includes 800m resolution long-term average estimates of the distribution of incoming precipitation and groundwater-sourced irrigation into contributions to the evapotranspiration (ET), quick-flow runoff, and effective recharge water budget components over the 2000-2013 time period, as well as annual estimates for the individual years. It also includes other data supporting the methods development that produced these maps, corresponding to the figures in the associated journal article. The estimates were developed with new empirical regressions for (1) quick-flow runoff data generated from a USGS-developed hydrograph separation program (PART) for 1434 gages as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO); and (2) long-term evapotranspiration from water balance estimates at 679 gages as a function of land cover (NLCD), precipitation (PRISM), and maximum, minimum, and mean daily temperature (PRISM), and a separate estimate for ET over open water. The recharge quantites close the water budget to sum to the total influx from precipitation. Irrigated water quantities reported in the 2005 USGS Water Use dataset are incorporated as effective additional precipitation. Estimates are included for both effective recharge, which reflects the quantity of water available to replenish the groundwater table, and total recharge, which also includes an estimate for the recharge quantity that was subsequently intercepted by riparian vegetation and converted to evapotranspiration. Methods are fully described in the associated accepted publication; this dataset will be updated with its complete citation when published.
