1. A long horizontal channel has a base width of 1 m and sides at 60◦ to the horizontal. When the flow in the channel is 0.85 m3 ·s−1 the depth is 500 mm. The discharge is suddenly reduced so that a surge wave of amplitude 150 mm is propagated upstream. Determine the new rate of flow, the velocity of the wave and the Froude numbers before and after the wave.
2. In a long rectangular channel 3 m wide the specific energy is 1.8 m and the rate of flow is 12 m3 ·s−1. Calculate two possible depths of flow and the corresponding Froude numbers. If Manning’s n = 0.014 what is the critical slope for this discharge?
