12-25. The rectangular channel has a width of 1.5 m, and the depth of the water is originally 2 m. If the flow is 4.50 m/s, show that the upstream flow is subcritical, and determine the required depth of the water, y', at the top of the bump so that the downstream flow can be transformed to supercritical flow. What is the downstream depth? Y2 52I DE-ST 2 m 26
