Abstract: This paper describes the hydrodynamic characteristics of a curtain-wall-pile breakwater, the upper part of which is a vertical wall and the lower part consists of an array of vertical piles. Mathematical models have been developed to compute wave transmission, reflection and run- up, and wave force acting on the breakwater for both regular and irregular waves. Large-scale laboratory experiments have also been conducted for curtain-wall-pile breakwaters with a constant spacing between piles but various drafts of the upper vertical wall. Comparisons between measurement and prediction show that the mathematical model adequately reproduces most of the important features of the experimental results for both regular and irregular waves. The curtain-wall-pile breakwater always gives smaller transmission and larger reflection than a curtain wall breakwater with the same draft as that of the upper wall, or a pile breakwater with the same porosity as that of the lower part, of the curtain-wall-pile breakwater.
