foredune

A foredune is a dune ridge, typically found at the landward edge of a beach, that has become stabilized by vegetation. Dunes, in general, are accumulations of sand shaped by wind and gravity. They can form in deserts, on beaches, and even on eroded farmland.12

Foredunes are a specific type of coastal dune. They form when the wind carries sand from the beach inland. Obstructions, such as vegetation, can hinder the wind's transport of sand, causing it to accumulate and form small mounds. If sediment supply is consistent and erosion doesn't destroy them, these mounds can develop into foredunes, which are the first line of coastal dunes. The sediment in dunes is usually well-sorted sand, and vegetation plays a crucial role in stabilizing them.3
