5. Given: Discharge = 400 cfs; upstream bottom width = 12 ft; upstream flow depth = 1 ft, downstream bottom width = 32 ft; length of transition = 100 ft. What should be the downstream flow depth (to an accuracy of 0.1 ft) for the hydraulic jump to occur approximately in the middle of the transition (Section 0 + 50)?

A trapezoidal channel has a bottom width 10 ft and side slope of 2H:1V. It carries a discharge of 250 cfs at a water depth of 4.8ft. The channel is to pass under a highway and a culvert is proposed for a smooth transition from the channel to the culvert. You are asked to design this transition under the following design criteria: First of all, it is important to keep in mind that the culvert shall not act as a...
