2. Water flowing at the normal depth in a rectangular concrete channel that is 12 m wide encounters an obstruction, causing the water level to rise above the normal depth at the obstruction and for some distance upstream. The water discharge is 126 m3/s, and the channel bottom slope is 0.00086. If the depth of water just upstream from the obstruction (yo) is 4.55 m, find the distance upstream to the point where...

A canoer is aimlessly paddling in the 15 m wide rectangular channel downstream of a dam. ...
A canoer is aimlessly paddling in the 15 m wide rectangular channel downstream of a dam. The water depth and discharge in the channel are 5 m and 175 m3/s respectively. The dam operator assumes that the channel is clear, and ‘instantaneously’ ramps up the discharge to 210 m3/s, creating a surge that moves downstream. If the canoer is 350 m downstream of the surge at the instant that the surge is created and is able to paddle 1.5 m/s more than the speed of the water below him, will he make it to the dock that is 175 m downstream of him before being hit by the surge?

Supercritical, uniform flow of water occurs in a 5.0 m wide, rectangular, horizontal channel. The depth of flow is 1.5 m and the flowrate is 45 cu.m/s. The flow encounters a 0.25 m rise in the channel bottom. What is the new normal depth? Is the flow after the rise subcritical, critical or supercritical? Assume frictionless flow
