• A beach ridge is a wave-swept/wave-deposited ridge running parallel to a shoreline.

• It is composed of sand.

• Littoral transport =The movement of sediment by wave action.

• Longshore transport = Movement of material parallel to the shoreline. 

• Offshore transport = Movement perpendicular to the shore.

• A beach ridge may be capped by sand dunes.

•  The height of a beach ridge is affected by wave size& energy.

• Isolated beach ridges may be found dry lakes in the western United States.Inland of the Great Lakes of North America.

• Some isolated beach ridges are found in parts of Scandinavia.

• Glacial melting relieved pressure on land masses and resulted in subsequent crustal lifting or post-glacial rebound.

•  A rise in water level can submerge beach ridges.

• Beach ridges may become routes for roads and trails.
