• Resumen

  • 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.
