The cross-section of a river channel is provided below. The distance x is measured from edge of the left-side channel. The point defining the left bank (LB) and right bank (RB) of the main channel are indicated. x Elev (ft) (ft) 0 330 30 326 55 324 75 322 115 320 LB 130 314 140 314 145 321 RB 175 322 195 324 225 326 245 330 The river has a water surface elevation of 326 feet and a friction slope of 0.001 ft/ft. The Manning's coefficients for the left, main, and right channels are 0.065, 0.045, and 0.065, respectively. a. Plot the channel cross-section and indicate the locations of the left, main, and right channels, and the water surface. b. Determine the flow area (A) (in ft2) for the left, main, and right channels. c. Determine the wetted perimeter (P) (in ft) for the left, main, and right channels. d. Determine the conveyance in the left, main, and right channels. e. Determine the flow rate (in cfs) in the left, main, and right channels. f. Determine the flow velocity (in ft/s) in the left, main, and right channels. g. Determine the total flow rate (in cfs) for the cross-section.
