A Numerical Simulation on Three-Dimensional Hydrodynamic Characteristics of Wave Height and Flow around Asymmetric Submerged Breakwaters

초록

In case of constructing submerged breakwaters for the purpose of preventing coastal erosion, the number of submerged breakwaters,as well as their asymmetry is dependent on the field conditions. The aim of the present study was to examine the 3-D hydrodynamic characteristics (3-D wave field, wave height, mean water level, and mean flow) around the asymmetric submerged breakwaters using a 3-D numerical model,LES-WASS-3D, which was validated through a comparison with existing experimental data and showed fairly nice agreement. From the numerical results, the wave height, mean water level, and mean flow are discussed in relation with the variation in the breakwater length ratio.
