Earth:Baymouth bar
From HandWiki
Short description: Sandbank that partially or completely closes access to a bay
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]
Background
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.[citation needed]
