This paper aims to examine how the slope angle of wave dissipating work influences the hydraulic performance of horizontally-composite breakwaters under irregular wave action. The hydraulic performance, in terms of reflection coefficient, transmission coefficient and energy dissipation rate, is assessed through a numerical tool of CADMAS-SURF/2D (V5.1). When the slope of wave dissipating work became gentler, its reflection coefficient tended to become lower, and its transmission coefficient experienced only a slight reduction, while an increase in the energy dissipation rate was observed. The numerical results were verified using not only hydraulic model experimental results but also empirical formulas found in the literature.
