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 currents now. Surprisingly, there are many types of rip currents that can occur on beaches, and these currents are created by a wide variety of mechanisms that are presented here, along with numerical, physical, or field validation. We also show the potential for prediction schemes for use by lifeguards and beach managers.

Characterization of the vertical structure of tidal currents in the Golden Gate (San Francisco) inlet Khalid, Muhammad (Monterey, California. Naval Postgraduate School, 2012-12);In the Golden Gate (San Francisco) inlet, tidal currents are dominant and have complex spatial and temporal variations owing to the large size of estuary connected through a narrow channel and the shallow ebb shoal (bar) ...
