Abstract
The flow processes in a scour protection around a mono-pile in steady current is described in relation to transport of sediment in the scour protection based on physical model tests. Transport of sediment in the scour protection may cause sinking of the scour protection. TYhis may reduce the stability of the mono-pile and change for instance the natural frequency of the dynamic response odf an offshore wind turbine in an unfacorable manner. The most importans flow process with regard to transport of sediment and sinking of the scour protection in found to be the horseshoe vortex.
It is found that a larger pile diameter relative to the size of the protection stones will cause a larger sinking and that two layers of stones will descrease the sinking relative to one layer of stones with the same size.
