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

Rip current spacing

Journal of the Oceanographical Society of Japan, 1976
Mass, momentum and energy conservation laws, including the radiation stress, are used to derive an equation of the eigenvalues of rip current spacing. A coastal region with linear bottom slope is divided into two parts: Offshore region and surfzone separated by the breaker line.

RCEX: Rip Current Experiment

2008
Abstract : The long-term goals are to understand surf zone processes related to rip current systems through field observations. Rip currents occur commonly on most beaches and dominate many. In the past decade, it is recognized that beaches with straight and parallel contours are not a stable morphologic configuration whereas more complex beaches ...

Rip-Current Systems

The Journal of Geology, 1958
Under certain conditions of near-shore slope and wave activity, the major seaward drainage of water which has been moved toward the beach in waves and breakers is in the form of rip currents. These currents are particularly well developed along the coast of New South Wales, where they exhibit a systematic form.

Hydrodynamic Instability Mechanism for Rip Currents

Studies in Applied Mathematics, 2015
On reexamining the hydrodynamic instability, Yu [1] showed that when the fully dynamical interactions are duly accounted for, and proper mathematical analysis is carried out, the positive feedback between the wave and evolving current can initiate and sustain rip current circulations with scales comparable to field observations on alongshore uniform ...

Wave‐current interaction models for rip currents

Journal of Geophysical Research: Oceans, 1978
Two analytic models are developed to describe rip current cells on an open coastline with sloping planar foreshore and flat offshore bathymetry. Both models extend the work of LeBlond and Tang (1974) to include the refraction of the normally incident wave field by the nearshore circulation.
