Abstract: The design and construction of a prototype mass armored breakwater is briefly described. The paper also explores the practicality of allowing the progressive interaction of design, physical model testing of design and construction to overcome the difficulties often encountered in the construction of rubble-mound structures when the rock source is undeveloped before construction is commenced. The results of the model testing, although somewhat limited to the solution of the specific problem, are further analysed to explore the relativity of high permeability in the design of structures of this type. This has resulted in the development of a computer model (HARBREM) which may be used as an initial design tool in the selection of armor sizes for physical testing. The development of this model is briefly described in the paper together with an example of model input and output.
