(Af160173)
Hydraulic jump is the jump or standing wave formed when the depth of flow of water changes from supercritical to subcritical state.When the slope of open channel decreases from steep to mild, the depth of flow of water increases toward the critical depth and a flow instability occurs at some point. The flow becomes turbulent until the new normal depth is attained in the downstream. This is called a hydraulic jump.

The application of hydraulic jump is:

Usually hydraulic jump reverses the flow of water. This phenomenon can be used to mix chemicals for water purification.

Hydraulic jump is applicable when flood happens...during flood the volume of water deposited is high and water current is huge. The big water current may break man-made structure. Therefore, hydraulic jump is best option to dissipate energy to avoid damage to structure. Hydraulic jump also applicable to slow down the flow to collect water such as water dam.

water changes from supercritical to subcritical state.

2)The hydraulic jump is necessarily formed to reduce the energy of water while the discharge downfalls a spillway. It becomes necessary to reduce its energy and maintain stable velocities, that phenomenon is called energy dissipation in hydraulic structure

Hydraulic jump occurs when the upstream flow is supercritical (F>1). To have a jump, there must be a flow impediment downstream. The downstream impediment could be a weir, a bridge abutment, a dam, or simply channel friction. Water depth increases during a hydraulic jump and energy is dissipated as turbulence.

Hydraulic jump is the phenomenon of open channels. Before defining the hydraulic jump it is necessary to describe the terms "super critical flow" and "sub critical flow" in order to clearly understand that "what is hydraulic jump" Hydraulic jump usually occurs in super critical flow.

Now move toward the hydraulic jump, it can be defined as rise in the level of water when the water transforms its super critical form into the sub critical one i.e. from unstable state to the stable one.

The application :

1. The place where hydraulic jump occurs, a lot of energy is dissipated in the form of heat energy. We can say that hydraulic jump is dissipator of extra energy of water.

2. used in spillways of the dam to reduce the erosive power of super critical flow. Otherwise it will affect the dam structure.
