Question

Quizplus · Accepted Answer

Beach swash is caused by the combination of breaking waves and longshore currents. Breaking waves generate the energy needed to create swash, while longshore currents provide the movement of water along the coast that results in swash. Other factors such as tides and currents can also contribute to swash, but breaking waves and longshore currents are the primary drivers. Upwelling and downwelling currents are not directly related to swash.
