  1. The discharge through a rectangular channel 4.4 m wide is 16 m3/s. The Manning’s coefficient n is 0.003.
    1. Determine the normal depth when the slope is 0.008. Check whether the flow is sub or supercritical.
    2. If the normal depth is to be kept at 2 m, determine the slope.

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.
