Sediment transport along the beach (parallel to the shoreline) caused by longshore currents and/or waves approaching obliquely to the shoreline. See Littoral Drift.



For an in-depth understanding of how beaches form and change (including longshore sediment transport), watch the 20-minute video The Beach - A River of Sand (1965) which was made by Doug Inman, a marine geologist at Scripps Institution of Oceanography.
