Undertow or Rip Current?Back in the old days, it was known as the "undertow," thatdreaded phenomenon that could sweep...Petrick, John
Arip currentis a dangerous current that occurs on a beach. Water is pushed up on the beach through the action of breaking waves, this water must escape back to sea. If the backwash water can dissipate along the shore uniformly, there is no problem. But if there is a feature on the be...

Water from the neck then flows into the "head," the region where water from the current spreads outward into deeper ocean waters and weakens. Rip Current vs. Riptide Believe it or not, rip currents, riptides, and undertows are all the same thing. While the word undertow suggests going un...
UndertowUndertow, rip current, and riptide are terms used to describe a variety of currents, all of which have different characteristics. However, much of the general public, news media, and even dictionary definitions confuse and misidentify these potential hazards at surf beaches. Many beachgoers...

A rip current is a narrow seaward flow of water from the beach to within, or more commonly to outside, the breaker zone. The name was first proposed by Shepard (1936). It now has replaced undertow,...Brenninkmeyer, Benno M.Springer US...
rip current, narrow jetlike stream of water that flows sporadically seaward for several minutes, in a direction normal or nearly normal to abeach. Such currents are probably the cause of mostoceanbathing accidents blamed onundertow. The termriptideis often used but is a misnomer, the currents ...
Apart from the incoming longshore current, one of the other contributions to the deflection rip flow volume is the Stokes drift. For shore-normal wave incidence, the Stokes drift is balanced by the offshore mean flow (the undertow), but for the obliquely incident wave considered here, it merg...
