Wind Erosion

There are two types of wind erosion
1)By Deflation, the wind picks up oarticles of fine grained sand and/or dust, moves and then deposites them elsewhere.
2)By Abrasion, the sandblasting like effect of windblown sand.

Onshore winds can lift sand from the beach and replenish the dunes behind the beach, but not today. Yet more sand is moving southwards along the beach.
