Monthly timescale quick-flow runoff maps for the conterminous U.S., 1895-2017

April 12, 2019
View Data Release

This dataset includes 1 km resolution monthly timescale estimates of the contributions to the quick-flow runoff component of the water budget over the time period from 1895-2017. These estimates were developed with a regression for surface runoff data generated from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1301 gaged watersheds as a function of surficial geology type (USGS), precipitation (PRISM), slope (NHD), and soil hydraulic conductivity (STATSGO). 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 an article in the Journal of Hydrology; this dataset will be updated with the complete article citation when available.

Estimating quick-flow runoff at the monthly timescale for the conterminous United States

The quantitative estimation of the quick-flow runoff component of streamflow is required for many hydrologic applications. Estimation at the monthly timescale and national spatial scale would be particularly useful for national water availability modeling. This paper reviews a sample of commonly used equations for quick-flow runoff, including several currently in use in continental-scale models. T
