Table 9. Bed-material data and transport rates in the Umpqua River basin, Oregon.
[Refer to appendix C for particle-size distributions and additional site descriptors. Site name: Many site names are informal labels developed for this study. Water surface slope: Used to calculate transport capacity. See text for data sources. Diameter: D50, grain size diameter in millimeters where 50 percent of sample is finer by volume. Surface-based calculations: Mean annual transport capacity for Umpqua River sites calculated for water years 1951–2008. Cow Creek sites at Riddle Bridge and USGS streamflow gaging-station computed for water years 1955–2008. Mobility index: Calculated as the reference transport discharge from Parker equation, divided by the 1.5-year flood discharge. Qt, P/Q 1.5 yr, Reference discharge predicted by the Parker (1990a, 1990b) transport capacity equation divided by the discharge for the flood with 0.67 exceedance probability (1.5-year flow). See text for complete description. Abbreviations: FPKM, flood-plain kilometer; RM, river mile; mm, millimeter; yr, year; USGS, U.S. Geological Survey; –, data not obtained or value not calculated]
