A hydraulic jump is a phenomenon of a sharp, spasmodic increase in the water level in the open channel during the transition of the flow from the so-called turbulent state to calm.
A hydraulic jump is observed, for example, when a stream of water flows out from under a dam installed on a river. In this case, at the very beginning of the channel following the dam, the water level is lowered, and at a certain distance from the dam it rises.
A hydraulic jump illustrates the mechanism of action of such an astrophysical object as a white hole .
The calculation of the hydraulic jump equation was carried out in 1838 by the French scientist Jean-Baptiste Belange .
