Water flows at 10 m3 /s in a rectangular channel of width 5.5 m. The slope of the channel is 0.15%, and the Manning roughness coefficient is 0.038. Use the following methods to estimate the flow depth 100 m upstream of a section where the flow depth is 2.2 m: (a) the direct integration method and (b) the standard step method. Approximately how far upstream of this section would you expect to find uniform flow?
