Varies in width depending on type of wave.

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

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

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