Tombolo

Tombolo

[tom-buh-loh]

A tombolo is a deposition landform such as a spit or bar which is attached to the mainland by a narrow piece of land. They usually form because the island causes wave refraction, depositing sand and shingle moved by longshore drift in each direction around the island where the waves meet. Eustatic sea level rise may also contribute to accretion as material is pushed up with rising sea levels. This is the case with Chesil Beach which connects the Isle of Portland to Dorset in England which is notable as the shingle ridge is parallel rather than perpendicular to the coast.
