#4 [5 points] A trapezoidal channel of bottom width 25 ft and side slope 1:2.5 carries a discharge of 450 cfs with a normal depth of 3.5 ft. The elevations at the beginning and end of the channel are 685 and 650 ft., respectively. Determine the length of the channel if n = 0.02. #5 [5 points] Water is flowing at a rate of 4.5 m3/s in a trapezoidal channel whose bottom width is 2.4 m and side slopes are...

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...

The specific energy diagram for a channel transition is shown on
the next page. The drop in the channel bottom has been designed
such that the decrease in channel width just barely avoids damming.
The upstream depth is 1.5 m, and the specific energy is 1.7 m.
Assuming a rectangular channel, what is the amount of channel drop
and the downstream width of the channel if the total discharge is
15 m3/s?

Problem 15.29 (GO Multipart) Part 1 Incorrect. Did you use the trigonometric relations to calculate the flow area? The area is trapezoidal in shape and can be determined by thinking of it as two triangular areas and a rectangular one Did you use the continuity equation?
