Swash aligned beach definition
SpletSwash, in geography, is known as a turbulent layer of water that washes up on the beach after an incoming wave has broken. The swash action can move beach materials up and down the beach, which results in the cross-shore sediment exchange. The time-scale of swash motion varies from seconds to minutes depending on the type of beach. SpletSwash carries sediment up the beach at an angle. Backwash carries sediment down the beach with gravity – at right angles to the beach. This creates a zig-zag movement of …
