If a river suddenly changes from a steep slope to a gentle slope, what kind of water surface profile would you expect to see right after the change?

When a river suddenly changes from a steep slope to a gentle slope, the water surface profile immediately after the change would typically exhibit a hydraulic jump. On the steep slope upstream, the water often flows at a high velocity and shallow depth, a condition known as supercritical flow. In supercritical flow, the water moves faster than a wave can propagate upstream, meaning disturbances cannot travel upstream. The Froude number, a dimensionless quantity comparing....
