Annual average recharge rates across the CONUS, 2000-2013

This dataset includes 800m resolution long-term average estimates of recharge rates over the time period from 2000-2013 and annual estimates for the individual years. These estimates were developed with new empirical regressions for (1) surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1509 gaged watersheds 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). The recharge quantites close the water budget to sum to [...]
