- This paper presents a mathematical model which computes the hydrodynamic characteristics of a curtainwall-pile breakwater using circular piles, by modifying the model developed for rectangular piles by Suh et al. in 2006. To examine the validity of the model, laboratory experiments have been conducted for curtainwall-pile breakwaters with various values of draft of curtain wall, spacing between piles, and wave height and period. Comparisons between measurement and prediction show that the mathematical model adequately reproduces most of the important features of the experimental results. The mathematical model based on linear wave theory tends to over-predict the reflection coefficient as the wave height increases. As the draft of the curtain wall increases and the porosity between piles decreases, the reflection and transmission coefficient increases and decreases, respectively, as expected. As the relative water depth increases, however, the effect of porosity disappears because the wave motion is minimal in the lower part of a water column for short waves.
