A hydraulic jump is likely to occur at which of the points in an open channel?

Question

Quizplus · Accepted Answer

A hydraulic jump is likely to occur at a point in an open channel where water moving at a high velocity at a shallow depth strikes water at a point where the depth of flow is substantially deeper. At this point, an abrupt rise of the water surface elevation forms (jump). A hydraulic jump is formed only if the flow is initially moving at critical speed before the transition to the area with deeper, slower moving water.
