2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.
A 8 m wide rectangular channel is carrying water at 180 m3/s
A 8 m wide rectangular channel is carrying water at 180 m3/s. The channel is constructed of concrete (Manning's N = 0.013) and is laid at a slope of 0.28 %. Find the normal depth

9) A rectangular channel 8 feet wide carries 2.5 ft/s of water at a depth of 3.2 feet. a) What are the most efficient attributes (d, A, P, and R) of the channel? b) If a 1-foot wide pier is placed in the middle of the channel, find the elevation of the water surface at the pier. What is the minimum width of the constriction that will not cause a rise in the upstream water surface?
Water flows within the 4-m-wide rectangular channel at 25 m3/s.
Water flows within the 4-m-wide rectangular channel at 25 m3/s. Take yA = 0.4 m. Part A Determine the depth of flow yB at the downstream end. Part B Determine the velocity of flow at A.

2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...
