| 11. | The littoral currents or Longshore drift transport sand southward along the eastern shore of Lake Michigan.
|
| 12. | The phenomenon is called longshore drift.
|
| 13. | Sediment sources can include river transport, sea cliff erosion and longshore drift into an area.
|
| 14. | Sediment is transported along the coast in the direction of the prevailing current ( longshore drift ).
|
| 15. | Still, the inlet is blamed for coastal erosion because it interrupts the longshore drift on the sound.
|
| 16. | Spits occur when longshore drift reaches a section of headland where the turn is greater than 30 degrees.
|
| 17. | In the summer, deposition is low because of lower runoff, southward longshore drift and northwest winds.
|
| 18. | Sediment sinks can include longshore drift of sediment away from an area and sediment deposition into an estuary.
|
| 19. | The mouths of all have been affected by longshore drift, particularly during violent storms during the Middle Ages.
|
| 20. | The wave pattern created by this water movement causes a convergence of longshore drift on the opposite side of the island.
