When waves approach the beach at an angle rather than head on, part of the wave's energy is directed perpendicular to the shore and part of it is directed parallel to the shore. The parallel energy generates the longshore current, which runs along the shoreline.

Longshore Currents, Shoreline, and Beach Drafts

WebCurrents - Longshore currents that are caused by waves hitting the island at an angle can move the sand from one end of the island to another. For example, the offshore currents along the east coast of the United States tend to remove sand from the northern ends of barrier islands and deposit it at the southern ends. WebA longshore current is a net movement that occurs as waves intersect the shoreline at non-perpendicular angles. Sand stirred up by waves in the surf zone is thus moved along the shore by longshore drift. Refraction process refers to the wave refraction as it changes direction of a travelling wave as it moves over the differing depths of ocean. portage county ravenna municipal court
