A reservoir feeds a rectangular channel 4.50m wide and a friction of 0.015 At the entrance, the depth of the water in the reservoir is 1.87m above the channel template. The channel is 240mts. In length and a drop in that length of 21.6cms the depth behind a spillway located at the end of the channel discharge is 1.24m Determine, using a single section the capacity of the channel assuming that the loss at the entrance is 0.25V2 /2 g.

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.

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.
