Summary
This dataset includes 800m resolution long-term average estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 2000-2013 and annual estimates for the individual years. These estimates were developed with a new empirical regression for surface runoff data generated 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). Irrigated water quantities reported in the 2000, 2005, and 2010 USGS Water Use datasets are also incorporated as effective additional precipitation. The contributing input datasets of saturated hydraulic [...]
Summary
This dataset includes 800m resolution long-term average estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 2000-2013 and annual estimates for the individual years. These estimates were developed with a new empirical regression for surface runoff data generated 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). Irrigated water quantities reported in the 2000, 2005, and 2010 USGS Water Use datasets are also incorporated as effective additional precipitation. The contributing input datasets of saturated hydraulic conductivity (Ksat) from STATSGO and an adapted surficial geology map are also included in this dataset. The quantities for quick-flow runoff do not include inter-pixel transfers, so do not capture within-watershed variations due to such transfers such as downstream runoff accumulation, but rather represent the portion of the precipitation entering each cell that ultimately contributes to the quick-flow runoff component. Methods are fully described in a concurrent accepted publication; this dataset will be updated with the complete citation when available.
These estimates were co-developed with estimates of evapotranspiration and recharge, so that the water budget is closed. These datasets are associated with this dataset entry.
