How do longshore currents form
WebLongshore currents are generated when a "train" of waves reach the coastline and release bursts of energy. The speed at which waves approach the shore depends on sea floor and shoreline features and the depth of the water. As a wave moves toward the beach, … As longshore currents move on and off the beach, “rip currents” may form around … WebThe longshore current and ____ combine to form the river of sand. beach face transport .

WebA rip current is another type of current that develops in the nearshore area and has the effect of returning water that has been pushed up to the shore by incoming waves. If part of a beach does not have a strong unidirectional longshore current, the rip currents may be fed by longshore currents going in both directions.
