Subeach

Subeach is a coastal landform that is submerged during high tide and exposed during low tide. It is typically found in areas with a gentle slope and a low tidal range, such as estuaries, lagoons, and tidal flats. Subeach sediments are often fine-grained, such as sand or silt, and are deposited by tidal currents. The subeaches are important habitats for various marine organisms, including birds, fish, and invertebrates, as they provide shelter and food sources. They also play a role in coastal protection by absorbing wave energy and reducing erosion. Subeaches can be temporary or permanent, depending on the tidal range and the rate of sediment deposition. They are often studied by geologists, ecologists, and coastal engineers to understand their formation, dynamics, and impact on coastal environments.
