A trapezoidal channel with bottom width of 10 m and side slopes of 1V:1.5H is carrying a flow of 80 m3/s. The channel bottom slope is 0.002 and n = 0.015. A dam is planned that will raise the flow depth to 10 m. Compute the flow depth by using standard step method in the channel 250, 500, and 750 m upstream of the dam.
A trapezoidal channel with a bottom width of 8ft and side slopes of 1V:1H is designed for a discharge of 160cfs. If the channel has a slope of 0.002, what will be the water depth if the Manning n is 0.017?
#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, b, of 10.0 m and a side slope ratio of 3:1. The Manning’s n of the channel is 0.025, and it is laid on a slope of 0.001. If the water depth is 2 m at the downstream end, write and submit an R script to compute the water surface profile for a discharge of 30 m3 /s. Also submit a plot of the water profile in elevation (m) for 1000 m channel...
A concrete-lined (smooth) trapezoidal channel with a bottom width of 10 ft and side slope 2 horizontal to 1 vertical has a slope 0,002 and is designed for a discharge of 160 cts. Determine the water depth in the channel,
Question 6 A concrete-lined trapezoidal channel with uniform flow has a normal depth of 1.5 m. The base width is 4 m and the side slopes are equal at 1 vertical to 2 horizontal. Mannin‘s n-0015. The bed slope 0.001 Compute the mean velocity and discharge. If the above channel were to be designed for flooding, it may have a section like in Figure below 8 m 8 m 4 m When the flow goes over the top of the...
What is the average velocity in a PCC lined trapezoidal channel with a bottom width of 10 m, 1:1 side slopes, a channel slope of 3% when it is flowing at a depth of 2m? The n-value for PCC is 0.013.
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...
clear handwriting please. write all steps please. Problem One: A trapezoidal channel of base width 20 ft and side slopes of 1.5H:1V is laid on a slope of 0.001, at a discharge of 1000 ft/s. Compute the flow and draw the surface profile upstream from the overfall to the region where the depth is 10 percent lower than uniform. Assume a manning n- 0.025 and that critical flow occurs at the overfall. Classify the profile.
A concrete-lined channel has a trapezoidal cross-section with a bottom width of 1.8 ft, side-slopes 1.5 (defined as horizontal: vertical), n the water depth is 2.7 ft, determine: (25 points) 2. 0.018, and a bed slope of 0.002 ft/ft. If a. Critica I depth (yd. Note: Because you need a solver to solve this problem (and I do not require a solving calculator for this midterm), all you need to do is set-up an equation that is in terms of...
