- What is the ratio of flow rates (Q1/Q2) for an open channel, when only the material of it is changed from riprap (n = 0.033) to concrete (n =0.012) and the other features are the same?Water flows in a trapezoidal channel having a bottom width of 15ft and side slopes of 1 vertical to 1.5 horizontal at a rate of 200cfs. Is the flow a subcritical or a supercritical flow if the depth of the flow is 2ft?Read the question carefully and give me right solution with clear calculations. At a certain location, the depth of flow in a wide rectangular channel (b y ) is 0.75 m. The channel flow rate is 1.6 m3/sec per unit width (Q/b), the bottom slope is 0.004, and Manning’s coefficient is 0.015. Determine the depth of flow 12 m downstream.

- Water Resources Engineering: You have designed a channel to to transport 5 m3/s using the most efficient rectangular section. The Manning's roughness coefficient is 0.019 and the bed slope is 0.0001 m/m. For this channel, determine: a. The normal depth b. Is the flow subcritical or supercritical c. Calculate what the new width of the channel would need to be to force the flow of water to be critical and state what the depth of water would be in this new channel. Neglect head loss through this transition (Note: this will no longer be the most efficient section). d. Show the transition on a specific energy curve.A rectangular channel carrying 30 cfs has a bottom width of 4 ft.
