  • 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.

  • 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.
