Bands of soft rock such as clay and sand are weaker and therefore they can be eroded quickly. This process forms bays. A bay is an inlet of the sea where the land curves inwards, usually with a beach.

When water loses its energy, any sediment it is carrying is deposited. The build-up of deposited sediment can form different features along the coast.

They are the dunes closest to the shoreline, dynamically linked to beach processes, and significantly influenced by wave action as both a constructional and erosional force. Foredunes develop at ...

Because of the growing hazard, the university said it was "crucial" to understand erosion processes, including how and when they might threaten buildings and other infrastructure built on cliffs.
