Water is flowing in a trapezoidal channel with a 10-ft bottom width and 2 on 1 side slopes. The Manning n value is 0.025, the discharge is estimated at 1000 cfs, and the channel bed slope is 0.009 ft/ft. At a certain point the depth is observed to be 7 ft.

a. Classify the profile that prevails in this vicinity.

b. What is the control of this profile and is it located upstream or downstream?

c. What would you expect to find upstream and downstream of this profile?
