Wave Numerical Simulation Study on Wave Run-up Considered Complicated Terrain

Wave run-up is an important factor in determining the top elevation of the seawall, revetment and other coastal engineering, It not only affects the cost of the project directly, but also relates to the project's safety, Previous study on breakwater are mostly focused on a single mild slope or steep slope, but a widely accepted model for simulating the wave run-up in complex terrain conditions have yet to be developed. In this paper, it is the first time to use one-dimensional BW model with MIKE21 to simulate wave run-up in regular and irregular wave spectrum respectively, and verifies the numerical results by physical model test results. Then a wave run-up simulation of one-dimensional in complicated terrain is applied to nuclear power projects in Hainan Changjiang. It not only provides a scientific basis for hainan changjiang nuclear project safety design on bank protection, but also provides a applicable and practical method for the research in wave run-up with complicated terrain.
