Numerical analysis of the Forchheimer coefficients and the maximum pressures for a dike with impermeable core and permeable Elastocoast layer

The Van der Meer formula for amour stability takes the Iribarren number, number of waves and damage level into account. It also contains a factor P which describes the “notional permeability” of the breakwater. This factor is based on the fact that a more permeable structure dissipates more energy and hence requires less heavy armouring. Its...
