Linear, prograding coasts are the consequence of a substantial supply of sediment derived by transport along the coast by longshore drift and coastal currents. |
As part of the restructure, artificial headlands were built to hold the sand and prevent longshore drift. |
In natural conditions marginal deltaic coasts benefit from sediment input from upcoast deltas via longshore drift and current-driven transport. |
At the southern margin, longshore drift induced by the southeasterly winds accumulated carbonate sands and gravel in a spit-platform, at the lee side of a protruding cape. |
Rising sea levels and longshore drift since the ice age have created a remarkable, 500 km-long beach. |
Most revetments do not significantly interfere with transport of longshore drift. |
