Rip current review

Coastal Engineering, 2006
Rip currents are shore-normal, narrow, seaward-flowing currents that originate within surf zone, extend seaward of the breaking region (rip head), and can obtain relatively high velocities. Within the last decade, there have been a significant number of laboratory and field observations within rip current systems.

Rip Currents

Annual Review of Fluid Mechanics, 2011
Rip currents are fast-moving flows, traveling “outward almost at right angles to the shore” ( Shepard 1936 ), creating a natural hazard for beachgoers, who suddenly find themselves in deep water. Field measurements and instrumentation, laboratory techniques, and numerical modeling have improved with time, enabling a more complete description of rip ...

Rip current instabilities

Journal of Fluid Mechanics, 2001
A laboratory experiment involving rip currents generated on a barred beach with periodic rip channels indicates that rip currents contain energetic low-frequency oscillations in the presence of steady wave forcing. An analytic model for the time-averaged flow in a rip current is presented and its linear stability characteristics are investigated to

PULSING AND CIRCULATION IN RIP CURRENT SYSTEM

Coastal Engineering 2004, 2005
Current pulsations from a longshore bar and trough rip system located on the eastern coast of Moreton Island, Australia are presented. These pulsations occur over 10-20minute intervals through the rip system and are correlated to both water level gradients and wave energy variations.
