1. Find the normal depth for a discharge of 350 cfs in a rectangular channel with a bottom width of 20.0 feet. The channel is concrete lined (n
 0.013) with a slope of 0.75 percent. Use Manning’s equation.

2. Refer to the channel cross section shown in problem 7 in Chapter 6. If the channel slope is 1.75 percent and the lining is concrete (trowel finish), what are (a) the discharge and (b) the velocity?
