Annual estimates of recharge, quick-flow runoff, and ET for the contiguous US using empirical regression equations, 2000-2013

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 evapotranspiration [...]
