Question: A channel of a Triangular section has 2 slopes. The upstream portion is 200m long with a bed slope ibs, 0.035, while the downstream section

A channel of a Triangular section has 2 slopes. The upstream portion is 200m long with a bed slope ibs, 0.035, while the downstream section is 600m long with a slope of 0.0002. For a manning's value, n, of 0.03 and discharge 12 m3/s it is known that the flow enters the channel from a reservoir at the critical depth, and at the downstream end of the system, the water level is at the normal depth. Determine the water surface profile on the first slope, including a full classification. Note 10 steps should be used in the profile computations.

Sketch the remaining water profile as you would expect it to occur along with the system, including an estimated classification for each change in profile.
