Coastal barriers, also known as beach barriers, barrier islands, or coastal dunes, are landforms that are mainly composed of sand and are usually located near coasts. These barriers are formed over time by the combined actions of wind, waves, and currents.

Coastal barriers form offshore landforms along many coasts of the world, serving to protect the coast from erosion, capture sediment, and provide habitat for both plants and animals. Coastal barriers can also act as natural barriers in areas vulnerable to the effects of storms and floods, shielding the coast from high winds, storm surge, and flooding while providing protection from erosion and allowing sediment to accumulate in the back barrier area.

Coastal barriers are also important for recreation. By providing a safe shoreline for swimming, fishing, and other activities, coastal barriers can serve to draw people to the coast for leisure activities.

In addition to recreational uses, coastal barriers are also important for coastal management. By providing protection from the effects of storms and floods, coastal barriers can reduce the effect of storm surge and flooding on coastal infrastructure and ecosystems. In addition, coastal barriers can act to reduce erosion of the shoreline, protect habitats for plants and animals, and capture sediment for beach renourishment.

Overall, coastal barriers are important landforms that serve a variety of purposes. By providing protection from storms and floods, recreation opportunities, and management strategies, coastal barriers serve as important components of coastal ecosystems.
