Abstract
In recent years, the failure of many large conventional type breakwater structures has led to a careful examination of the physical processes of wavestructure interaction. Although naturally armouring structures, which gain their stability as a consequence of profile readjustment due to wave action, have been around in various forms for hundreds of years, the high incidence of failure of conventional structures has led to their increased use in the past decade. The interaction of an incident wave with a rubblemound breakwater results in complex flow patterns involving unsteady non-uniform flow (Hall (1987)). In most cases, it is desirable to construct a breakwater which works in harmony with the flow field; that is to construct a structure with a geometry and armour stone weight gradation which results in natural profile readjustment and subsequent minimization of the applied hydrodynamic loadings.
