Water is flowing in a 5m-wide rectangular channel running on a slope of 0.0065 m/m with a manning n value of 0.035. the discharge is estimated to be 21 m3 /s. at a certain point the depth is observed to be 3 m. (a) classify the profile that prevails in this vicinity (b) where is the control located for this profile (upstream or downstream)(c) what would you expect to find upstream and downstream of this profile?
