How is a baymouth bar formed?
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.
How are Tombolos made?
A tombolo is formed when a spit connects the mainland coast to an island. The process of longshore drift occurs and this moves material along the coastline. Material is pushed up onto beaches at an angle when the swash brings it onto the coastline at a 45 degree angle.
What do the terms swash and backwash describe?
The terms swash and backwash collectively refer to the oscillatory motion of the shoreline due to the continuous arrival of waves. They also describe the associated thin lens of water behind the moving shoreline that periodically covers and uncovers the beach face.

What is the difference between a bay-mouth bar and Bay-Head bar?
Bay-mouth bar s may extend partially or entirely across the mouth of a bay; bay-head bars occur at the heads of bays, a short distance from shore.
What is the difference between a spit and a baymouth bar?
