Coastal landforms can be formed either by erosion or by deposition. There are four types of erosion by waves: The longshore currents are created when waves are refracted while entering into shallow water. These waves slow down and the wavelength shortens in front of the headlands, but waves in the bays continue at the same speed and wavelength because they have not yet come into the shallow water.

This means that the bathymetry (the underwater elevation) of the ocean or sea bed also impacts the strength of waves. Where a bay is formed, there may be a headland on one side, extending into the body of water. The protected embayments, where wave action is subdued between headlands, are often transformed into sandy pocket beaches.

As a result, most of the breaker energy is concentrated along the relatively short section of the shore around the tips of the headlands, while the remaining wave energy is spread out along the much longer shoreline of the bays. Transportation and deposition processes produce distinctive coastal landforms (beaches, recurved and double spits, offshore bars, barrier beaches and bars, tombolos and cuspate forelands), which can be stabilised by plant succession.
