Baymouth bar

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

A baymouth bar is a depositional feature as a result of longshore drift. It is a sandbank that partially or completely closes access to a bay.[1]

These bars usually consist of accumulated gravel and sand carried by the current of longshore drift and deposited at a less turbulent part of the current. Thus, they most commonly occur across artificial bay and river entrances due to the loss of kinetic energy in the current after wave refraction.
