A strand plain is a type of coastal landform that typically consists of a relatively flat or gently sloping expanse of sand or gravel found along the shoreline. Strand plains are often formed by the accumulation of sediment deposited by waves and currents, creating a broad area of sandy terrain that may be influenced by tidal action and other coastal processes. Strand plains can be characterized by features such as dunes, beach ridges, and occasional low-lying areas that may hold water.
