A beach ridge is a low, elongated ridge that forms parallel to the shoreline, often composed of sand, gravel, or shell material. These ridges are created by the action of waves and currents and can indicate former positions of the shoreline. Beach ridges are significant in coastal geology for reconstructing past sea levels, storm events, and changes in coastal dynamics.
