摘要

Traditionally the hydrodynamic response of rubble mound structures are studied in physical models scaled according to the Froude scaling law which neglects viscous forces. This introduces scale effect because the inherent length scaling of the stone diameters creates laminar flow in the regions which in prototypes are dominated by turbulent flow. Numerical modelling of the flow do not have this draw back and is therefore attractive.
