Swash is the movement of a thin layer of turbulent, foaming water up a beach following the breaking of a wave. As this water rushes along it carries sand and shell fragments with it, depositing them when it runs out of energy. Flat waves, which have a very strong swash, often move a lot of material on to a beach in this way. Some of the swash soaks into the beach, while the rest returns to the breaker zone as backwash; the edge of a zone of swash action is often marked by a line of seaweed and driftwood. Research Swash
