The turbulent air–water interface and flow structure of a weak, turbulent hydraulic jump are
analyzed in detail using particle image velocimetry measurements. The study is motivated
by the need to understand the detailed dynamics of turbulence generated in steady spilling
breakers and the relative importance of the reverse-flow and breaker shear layer regions
with attention to their topology, mean flow, and turbulence structure. The intermittency factor
derived from turbulent fluctuations of the air–water interface in the breaker region is found to …
