Question

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

Answer 1

The channel distance affected by the weir

Yn ( Normal depth ) = 5.71 ft

Yc ( critical depth ) = 4.11 ft

x = 22794 ft
