1. A 6.0-foot-wide rectangular channel has a normal depth of 2.45 feet. (a) What is the cross-sectional area of the flow? (b) What is the wetted perimeter? (c) What is the hydraulic radius?

2. A channel conveys a discharge of 210 cfs at a velocity of 5.45ft/s. Find the cross-sectional area of the channel.
