Hydraulic jumps and stilling basins [PDF]
, 2015 A hydraulic jump is a rapid transition from a high-velocity open channel flow to a slower fluvial motion. It is commonly experienced in streams and rivers, in industrial channels, during manufacturing processes and downstream of dam spillways. The air is entrapped at the jump toe that is a discontinuity between the impinging flow and the roller.
