WebFor each reach, mean elevation, mean channel width, and slope were calculated. We used Snyder et al.’s (2003) ﬁeld-measured bank-full width data for Oat Creek and Kinsey Creek. Elevation and slope data were derived from 10-m-resolution U.S. Geological Survey digital elevation data as WebIf not, you need to measure the width of the water and take 3 or 4 depth measurements to get an average depth. With an average depth and a width, you can compute an area. Correction factors to convert surface velocity to average velocity typically range from 0.8-0.9. Many times 0.85 is used.

WebFigure E.2—Active channel width and hydraulic radius. For channels with gradients greater than 1 percent, and where the flow depth is shallow with respect to the channel-bed particle size (relative submergence, R/D 50, values less than 10), Bathurst (1987) suggested using discharge-per-unit width instead of average boundary shear stress WebSep 25, 2015 · The crux of the matter is finding a quantitative definition of "width" of the channel. Consider a point P located anywhere within the river. The width certainly cannot be any less than the shortest distance from P to the left bank plus the shortest distance from P to the right bank. A moment's thought suggests this is an excellent candidate for the …
