Given: There is a rectangular weir that causes the water level in a trapezoidal concrete-lined channel to be 13.1 ft from the channel bottom. The channel has a bottom width of 9.8 ft and side slopes of 2H:1V. The slope of the channel is 0.0005 and the discharge rate is 706 cfs.

Find: Channel distance affected by the weir.

Answer: yn=5.49ft, yc=4.11 ft, M1 curve, x=15,495 ft using dy=0.1 ft
