The flow in a very wide rectangular channel tends to a freefall at which the depth is reduced to 0.67 times the normal depth. The channel conveys a specific discharge of 4 m3/s/m and has a bed slope of 10 cm/km. Estimate the distance upstream of the fall where the water depth is 0.9 times the normal depth. Take the Manning coefficient as 0.025 and use the step-by-step (direct step) method.

Water approaches a sharp-crested rectangular weir through a channel that is 2 m wide. The depth of flow in the channel is 1 m. The weir crest is 0.6 m above the base of the channel and has a crest width of 0.8 m. It is located in the centre of the channel. Assuming a coefficient of discharge of 0.61, and ignoring side contractions, determine the discharge over the weir: a) Assuming the approach velocity is zero b) Including the...

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.
