碩士 / 國立中興大學 / 土木工程學系所 / 101 / In this study, a numerical simulation was presented to investigate the variations of wave height and water level between a submerged breakwater and a vertical seawall. The study also investigated how different flow depths affected wave height, water level, and wave condition between a submerged breakwater and a vertical seawall. Application of Renormalized Group k-Ɛ turbulence model to simulate turbulent transmission of waves was used to solve the control equation of Reynolds Averaged Navier-Stokes Equation (RANS), selecting FLOW-3D fluid dynamics to calculate and analyze the simulation of the system. After comparison with Hur et al. (2003) experiment and simulation results, this simulation showed nice accuracy in water surface variation and horizontal velocity. The simulation results show that when the waves by the submerged breakwater, the water set-up behind submerged breakwater due to the wave breaking. In the Gateway between two submerged breakwater the rip current will produce due to the water set-up behind submerged breakwater. If the seawall existed, the water accumulates between a submerged breakwater and a seawall, establishing a higher mean water level.
