摘要：A 1 D wave breaking model is developed based on an existing set of second-order fully nonlinearity Boussinesq equations. The discretized equations are solved numerically on a staggered grid using a higher-order finite difference scheme. The non-reflective boundary condition for incident wave is achieved by deriving a standing wave solution of the equations and using a relaxation wave generation technique. The 1 D wave breaking model is used to solve the problem of water sloshing in a closed container. The shoaling of a solitary wave on a plane beach is simulated by the model in an effort to illustrate the importance of retaining full nonlinearity. The shoaling and breaking of regular waves on a sloping plane beach is studied numerically using the model. The result shows that there is a satisfactory agreement between the numerical simulation and the experimental data, which demonstrates the effectiveness of the 1 D wave breaking model.
