= Hydraulic jumps in rectangular channels
{wiki=Hydraulic_jumps_in_rectangular_channels}
Hydraulic jumps are sudden changes in the flow regime of water that occur in open channel flow, such as in rectangular channels. They are characterized by a transition from supercritical flow (where the flow velocity is greater than the wave speed) to subcritical flow (where the flow velocity is less than the wave speed). This phenomenon is crucial in fluid mechanics and hydraulic engineering, as it affects the energy, momentum, and flow depth of the system.
