How are pocket beaches formed / shaped?
Pocket beaches are formed when material from adjacent headlands and bluffs is eroded by wave action, and transported by waves and currents. Due to refraction, waves converge on headlands, causing erosion, and diverge in coves, causing deposition of sediment (see waves). The shape of pocket beaches is determined by the form of the surrounding bedrock. The forces of waves, currents and tides determine the type and amount of sediment deposited.
