A coastal dune is formed with sand carried by ocean currents to the beach and stuck on the shore by the wind. The dune in Sindu-ri is formed along the northwestern coast of the Taean Peninsula, measuring 3.4km long and about 0.5-1.3km wide. It acts as a buffer zone between the land and sea and, like a desert, shows ripples in the sand caused by the wind. The Sindu-ri dune is located behind the beach of the Sindu-ri arm of the sea. The conditions are favorable for the formation of dunes since the area is exposed to the prevailing northwestern wind in winter; since the nearby area is mostly composed of sand, the wide tidal flat and shore are exposed at low tide, allowing the wind to carry the sand to the land. The sand dune clearly shows the development of a varied topography including the fore dunes, dune wetland, and barchans, which are arc-shaped sand ridges. The Sindu-ri coastal dune is a feature of the sedimentary topography of the seashore. It is well-preserved, serving as valuable material for the study of sand dune formation and the paleoenvironment as Korea’s largest sand dune of its kind.
