Besides stability, the most important criterion in the design of rubble mound
breakwaters is the serviceability, that is mostly determined by wave overtopping.Wave overtopping discharges are usually estimated using empirical formulas
available in the literature. The effect of different armor layer units on wave
overtopping is reflected in accepted design specifications using roughness
coefficients (γf). However, the effect of different placement methods of these units
has not been fully addressed and discussed. The different antifer placement
methods proposed in the literature, namely closed pyramid, double pyramid and
irregular placement methods, were used and experiments were carried out in a
total of eight different armor layers, considering the different packing densities.
The results of the experimental studies show that different antifer unit
placement methods significantly change the wave overtopping discharge. Based
on the experimental results, new roughness coefficients (γf) are proposed for
different antifer unit placement methods.
