Question

A rectangular channel has a bottom width of 6.0 ft, and a longitudinal slope of 0.3% (So = 0.003). The discharge is 90 cfs.

(a) Determine normal depth if n = 0.014 (concrete channel)
(b) Determine normal depth if n = 0.022 (vegetated channel)
(c) Determine critical depth (does n matter?)
(d) Determine category of channel slope (mild or steep) if the channel is concrete. State reason.
(e) Determine category of channel slope (mild or steep) if the channel is vegetated. State reason.
(f) Compare your answers to (d) and (e). Can you determine the channel slope category just by looking at the numerical value of S?

(g) Water depth is 2.0 ft at one point. Determine the type of profile in a concrete channel. Make a sketch.

(h) Water depth is 2.0 ft at one point. Determine the type of profile in a vegetated channel. Make a sketch.
