A vertical sluice gate in a long rectangular channel 5 m wide is lowered to produce an opening of 1.0 m. Assuming that the free flow conditions exist at the vena contracta downstream of the gate verify that the flow in the vena contracta is supercritical when the discharge is 15 m3/s and determine the depth just upstream of the gate, Cv = 0.98; Cc = 0.6.

A 5-m wide rectangular channel with two reaches, each with a different slope, conveys 40m3/s of water. The channel slope for the first reach is 0.0005 and then a sudden change to a slope of 0.015 so that critical flow occurs at the transition. Determine the depths of flow at locations 10 m, 20 m and 30 m upstream of the critical depth. The Manning’s n for the channel is 0.015.
