Water is flowing in a wide rectangular channel with a specific discharge of 10

/s that is run ning on a slope of 0.025 m/m. The estimated Manning n value is 0.015 (metric). If the observed velocity at a point is 3 m/s,

a. classify the profile that predominates in this vicinity.

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

c. What do you think is located upstream and downstream of this profile?
