DAMAGE FUNCTIONS FCR A RUBBLE-MOUND BREAKWATER UNDER THE EFFECT OF SWELLS

Juan B. Font

Abstract


In this paper experimental data are given to aid in the design of a rubble-mound breakwater The use of armor damage functions is supported rather than the use of the wave height for the no damage condition Damage curves defined experimentally are proposed, for both rocks and tetrapods, for different wave storm durations and for different placing tech niques A determinant influence of storm duration is found for advanced damage of the armor layers The experiments with different placing techniques showed that stability coefficients based upon the no damage criteria, do not give a reliable picture of the ultimace strength of a rubble-mound breakwater.
