WebRip currents often occur where there is a channel between sandbars that makes it easier for the retreating water to escape. As shown in Figure 13.2.3, rip currents flow straight out … WebThis can occur when there are gaps in sand bars nearshore, from structures like piers or jetties, or from natural variations in how waves are breaking. Rip currents can move faster than an Olympic swimmer can swim, at speeds as fast as eight feet (2.4 meters) per second.
WebThese longshore currents are a primary agent of coastal movement; they are a major cause of sand migration along barrier and mainland beaches.
