This paper discusses the stability under wave action of breakwaters, seawalls or harbour walls formed by un-grouted stone or concrete blockwork. The loading on blockwork caused by the interaction between wave action and 'internal flows' in the hearting of the breakwater is calculated. Two loading cases were investigated for two different breakwaters: loading by wave impact; and loads at wave run-down. For the situations simulated, the response to wave impact loads was more or less independent of the permeabilities of the exterior blockwork and of the hearting or core of the structure. Loading during wave rundown is shown to be highly dependent on these structural parameters.
