A trapezoidal canal has a longitudinal slope of 1 %, side slopes of 3:1 (H:V), a bottom width of 10.0 ft, a Manning's n of 0.015X, and carries flow of 700 ft³/s. The depth of flow at a gaging station is observed to be 3.5 ft. X is the last digit of your ID. For example, if your ID is 0155497, the manning's n would be 0.0157. (1) What is the normal depth of flow in the channel? (2) What is the critical depth of flow in the channel? (3) Classify the slope of the channel and the water surface profile at the gaging station.

Transcribed Image Text:A trapezoidal canal has a longitudinal slope of 1 %, side slopes of 3:1 (H:V), a bottom
width of 10.0 ft, a Manning's n of 0.015X, and carries flow of 700 ft³/s. The depth of flow
at a gaging station is observed to be 3.5 ft.
X is the last digit of your ID. For example, if your ID is 0155497, the manning's n
would be 0.0157.
(1) What is the normal depth of flow in the channel?
(2) What is the critical depth of flow in the channel?
(3) Classify the slope of the channel and the water surface profile at the gaging
station.
(4) How far from the gaging station is the depth of flow equal to 3.8 ft? does this
depth occur upstream or downstream of the gaging station?
