On the predictability of the notional permeability of breakwaters as a function of core properties

To determine the nominal diameter of armour rock for a rubble mound breakwater, the ‘Van der Meer’-formula is frequently used. It requires the so-called 'notional permeability' parameter P, which has been defined for a limited number of structures. Often designed structures deviate from these defined lay-outs. To determine the notional...
