be preserved, and how their immobilization by vegetation can be counteracted by introducing techniques that reactivate the aeolian processes. Four such techniques (rotary cultivator, beach sand cleaner, disc harrow and excavator) were evaluated during an 8
the effect of the different techniques. Both field experiment and model simulation showed that the most effective method is the beach sand cleaner, followed by the rotary cultivator.
