A triangular concrete (n=0.013) channel having a side slopes 2H:1V is designed to carry a flowrate of 200 cfs at a normal depth. The channel bed slope is 0.1%.

a) Determine the state of flow (regime).

b) Farther downstream the channel slope changes to 0.9%. Determine the new state of flow. c) Classify channel slope. Sketch the water surface profile from upstream to downstream sections.
