These coves are formed by waves breaking through an outer layer of hard rock, such as limestone, and then, over time, the waves sweep away the soft rock further inland, like sand and clay, creating a cove. UNCLAS implemented a universal system for maritime boundaries based on baselines, which are measured from the low-water line at the coast. Even London is built along the River Thames, which flows into the North Sea. These Dalmatian types normally occur .

It is used in geography and meteorology and is usually associated with coastal erosion.It plays a large part in longshore drift as well. An example of a popular cove situated in a concordant coastline is the Lulworth Cove. A combination of geological structure and sea level riseproduces the morphology of landforms aligned parallel to the coastline. A concordant coastline is an arrangement of rock strata along the coastline. Consequently headlands and bays form along discordant coastlines and whilst headlands remain exposed to the force of the waves, bays are sheltered. e.g. The high degree of indentation of Bantry Bay is not solely influenced by the relative resistance of rock types, but also the orientation of strata SW-NE means that they directly face high energy Atlantic waves driven by the prevailing SW wind.
