Question: A rectangular channel is 1 0 . 0 ft wide and carries a flow of 4 5 0 cfs at a normal depth of 3

A rectangular channel is 10.0 ft wide and carries a flow of 450 cfs at a normal depth of 3.2 ft. Mannings nn =0.017. An obstruction causes the depth just upstream of the obstruction to be 8.0 ft deep. Will a jump form upstream due to the obstruction? If so, how far upstream?
