Varies with tides. Waves up and down as swash and backwash.

Broken waves travel towards shore. Sediment movement may be onshore/offshore/along coast.

Waves are modified and sediment movement occurs, e.g. deposition.

Varies in width depending on type of wave.

Where cliff/land is.

Sand dune, beach ridges, beaches or cliffs may or may not be present here. Only affected by waves under storm conditions.

Water depths greater than half the wave length of incoming wave. Limited sediment movement by waves. Tidal currents most effective.
