Consider the same two channels of quiz 2 with bed slopes respectively equal to 0.001 m/mand 0.01 ...
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...
A 4-m high dam with a slope of 8:1 ?V) has been proposed to ensure steady water levels in a rectangular channel with a width of 5 m, a bottom slope of 0.2%, a Manning's n of 0.02, and discharge rate of 10 m3/s as shown below. proposed aim So-0.002 1. (15 points) Sketch out the gradually varied flow profiles for the water surface around the proposed dam by hand a. Determine the critical depth for the channel b. Estimate...
Q1) Figure below indicates a rectangular channel connecting two reservoirs. The ch 385.88 m at the 1.22 m. The upstream gate is open by 61 cm. Thus, water is released to the channel at a rate of 15 cms l consists of rent properties given in the table below. The water surfaces locate at elevations 388 3) thre upstream and downstream reservoirs, respectively. The depth at the upstream a) Determine normal and critical depths in each reach. Classify the reaches...
Specific discharge of a wide rectangular channel is 10.0m2/s (Q 10.0m3/s/m). The channel consists of two long reaches having the following bed slope, So1 -0.0001 (for ABC), and So2 = 0.008 for (CDE), (see Figure 1) respectively. There are two gates to control the flow and the flow depth at the vena contractor after each gate is approximately 0.3m. Take the Manning's coefficient as 0.015 Locate every possible flow changing locations and, sketch and name the water surface 1. profiles...
