Journal ArticleDOI
Rip current review
TL;DR: An overview of the rip current kinematics based on these observations and the scientific advances obtained from these efforts are synthesized in this article, where rip current flows are partitioned into mean, infragravity, very low frequency (vorticity), and tidal contributions, and it is found that each contributes significantly to the total.
Journal ArticleDOI
RIPEX: Observations of a rip current system
TL;DR: Rip current kinematics and beach morphodynamics were measured for 44 days at Sand City, Monterey Bay, CA using 15 instruments composed of co-located velocity and pressure sensors, acoustic Doppler current profilers, and kinematic GPS surveys as mentioned in this paper.

TL;DR: In this paper, a sequence of daily beach surveys acquired over one month covering an area larger than 100,000m 2, was analyzed to study morphological changes resulting from a cluster of storms.
Journal ArticleDOI
Mean Lagrangian flow behavior on an open coast rip-channeled beach: A new perspective
Jamie MacMahan,Jeff Brown,Jenna Brown,Edward B. Thornton,Ad Reniers,Ad Reniers,Timothy P. Stanton,M. Henriquez,E. L. Gallagher,Jon Morrison,Martin Austin,Tim Scott,Nadia Senechal +12 more
TL;DR: In this paper, a fleet of 30 position-tracking surfzone drifters were deployed on an open coast beach in Monterey, CA during multiple rip current occurrences, and the authors measured spatially synoptic estimates of rip current flow patterns, vorticity, and Lagrangian transport behavior.
Journal ArticleDOI
Rip currents, mega-cusps, and eroding dunes
TL;DR: In this article, the authors show that dune erosion occurs at the embayment of beach mega-cusps O(200m alongshore) that are associated with rip currents.
