A 50 m3/s is conveyed down a 5-m wide rectangular channel (n = 0.012) with a slope of 0.02 m/m. The channel transitions into a second channel with a slope of 0.0008 m/m. A hydraulic jump occurs on the downstream channel. What is the downstream depth of the second channel after the jump? What is the depth of the water before the jump? What is the energy loss due to the jump? How long is the total distance of the...
