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.
