A small spillway with a height of 3 feet is located in a rectangular channel 14 feet
wide with a bottom slope of 0.01 and a roughness coefficient of 0.03. The loss
coefficient for flow over the spillway is 0.2. The flow rate is 175 cfs. Determine
how far upstream from the spillway the depth of water will be within 1% of the
normal depth.

Answer #1

At first the normal depth is to be calculated. Then the energy depletion is to be calculated. After that we will calculate the energy slope. Finally the length of water surface profile is to be calculated.

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.
