coastal dunes

Shoreline sand hills

Coastal dunes are hills of sand formed by wind along shorelines.

They develop where waves deposit sand that dries and blows inland, accumulating around vegetation or other obstacles.

Coastal dunes serve as natural barriers against storms and erosion, protecting inland areas from flooding: The coastal dunes were damaged during the hurricane.

They host distinctive ecosystems of salt-tolerant grasses and wildlife adapted to shifting, sandy environments.
