Answer 2

The following is the most essential condition for the hydraulic jump to form:

• Prior to the hydraulic leap, fluid is usually flowing turbulently but smoothly. When the initial speed is lower than the critical speed, a hydraulic leap is not feasible.
• A hydraulic jump is a jump or a standing wave that is formed when the depth of flow of water changes from a supercritical to a subcritical state. When the slope of the open channel decreases from steep to mild, the depth of flow of water increases toward the critical depth, and flow instability occurs at some point.

Why does a hydraulic jump form?

• When a fast-moving open flow becomes unstable, a phenomenon known as a hydraulic jump happens. When a jump happens, the liquid surface height quickly rises, increasing the depth and slowing the average flow velocity downstream.
• What are the conditions required for the formation of hydraulic jump in a channel with respect to type of flow and Froude number?
• If the depth of flow is below the critical depth or the Froude number is higher than 1, the current flow must be a shooting flow in order for a hydraulic jump to occur.
