Discordant coasts have a crenellated pattern of projecting headlands and indented bays. They are gentle, flat waves with a strong swash and a weak backwash; as a result, constructive waves build beaches. Tectonic forces produced by the collision of African and Eurasian plates compressed Carboniferous Limestone during the Alpine Orogeny 50 million years ago. They are, for the time being, out of reach of the current wave action and will therefore not be affected by them. Because the waves are so frequent, the backwash has less time to soak into the sand.

Waves interact with land through three major marine processes: erosion, transportation, and deposition. Coastlines are very important to people because they have many uses, but mankind is also placing coastlines under severe threat. The time wind takes to blow, wind speed and the fetch (distance the sea has covered) influence wave sizes. Waves move up and down there is no horizontal movement. During the Devensian glacial the sea level was about 100 m lower than today as water was retained in huge ice sheets. In addition, as waves approach a coast, they are refracted so that their energy is concentrated around headlands but reduced around bays.
