Description :
The frequency distribution of the general wind at Valkenburg is analysed and combined with the horizontal wind velocity pattern within blowouts. A simulation model, producing the spatial distribution of the wind power shows that the prevalence of algal crusts at the SW side of blowouts agrees well with the location which reaches the lower wind power values. In other parts of the blowouts algal crusts are damaged by moving sand at times of high wind velocity.
