Fluvial transport of bedload, suspended sediment, and silicate solutes in watersheds of western Oregon and northwestern California (1901-2016)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-27T00:00:00Z
These data sets contain the estimated fluvial transport of bedload, suspended sediment, and silicate solutes in the watersheds of western Oregon and northwestern California. The estimates for bedload represent mean conditions that existed during the 20th century, the estimates for suspended sediment represent mean conditions that existed between 1983 and 2012, and the estimates for silicate solutes represents mean conditions that existed between 1951 and 2016. The file “All_HUC12_fluvial_transport.txt” contains landscape attributes and estimates of fluvial transport for each component of the total fluvial load for all watersheds. The file “Select_HUC12_total_yields.txt” contains much of the same information as found in file “All_HUC12_fluvial_transport.txt” for a subset of those watersheds, in addition to the total fluvial yields, the fraction of the total yields contributed by each component, and estimates of landscape denudation rates based on those total yields.
