Numerical Investigation on the Influence of Breakwater and the Sediment Transport in Shantou Offshore Area

The coastline of Shantou is tortuous, while the hydrodynamic environment complicated. In this paper, model established by FVCOM (Finite Volume Coastal Ocean Model); open boundary conditions such as water level, river, and wind field are input; verified tidal harmonic function. According to previous research, typhoon with a 10-year return period selected for storm surge simulation. When there bank, accumulated on land cannot enter ocean due block bank but accumulates inner side resulting in higher water, less than 0.5 m. aspect sediment deposition, transport analyze deposition Port its surrounding waters. Some reasonable suggestions put forward Shantou. simulation results, following conclusions can be drawn: (1) case 10 years, effectively protect inland. Still, will collect near bank. (2) offshore level rise 0.4 m after adding (3) Bay mainly comes from caused tides, largest sedimentation occurs main channel.
