In the last decade a renewed interest has been shown for the berm breakwater concept. In the design of a berm breakwater many limit states have to be checked: stability of the armour layer in both cross and longshore directions, compliance of the secondary layers with filter rules, stability of the toe under wave attack, geotechnical stability, overtopping, etc. In this paper attention will be focussed on the stability of the outer armour. Special attention is given to the longshore transport case. It will be shown that only a probabilistic approach provides an insight into the sensitivity of the associated failure mechanism.
