Refer to the cross section shown in problem 14 in Chapter 6. If the channel has a uniform earth section lined with riprap and the slope is 3.00 percent, what are (a) the discharge and (b) the velocity?

Refer to the channel cross section shown in problem 7 in Chapter 6. Disregard the water level shown in the cross section, and find a new normal depth if the channel slope is 1.25 percent and the discharge is 300 cfs. The lining is concrete (trowel finish).
