A 8-m wide rectangular channel carries a flow of 96 m3/s at a flow depth of 4 m. The channel width is constricted to 6 m in a length of 5 m. Assuming the channel transition has straight and vertical sides, and there are no losses, plot the water-surface profile in the transition. Hint: you should find the water depth when the channel width is 8 m, 7.5 m, 7 m, 6.5 m, and 6 m.

    2. A 2.5 m wide rectangular channel conveys m wide rectangular channel conveys water at a normal depth of 2 m. In a part of the channel, the channel width is expanded to 5 m. The local energy loss due to this expansion is about 10% of the upstream velocity head. If the channel slope is 0.03% and the Manning roughness coefficient is about 0.012, calculate the water depth over this transition and show the situation with a simple sketch.
