Basic Processes - Sand Movement


The photo shows sand moving on a windy day in October 2001. The lighter-colored dry sand which is moving is visible against the darker color of wet beach sand.

A number of aeolian (wind) processes are at work in this photo. Sand movement starts on the beach where sand grains are picked up by the wind (entrainment) and the surface lowers (erosion). The sand is transported towards the foredune. Sand is deposited in the foredune vegetation.
