Abstract

In order to investigate the applicability of the water wave equation under the assumption of gentle slope on steep submerged breakwater, a finite difference calculation model was established for a group of double-layer Boussinesq water wave equations to numerically simulate the wave propagation process on the trapezoidal submerged breakwater with the slope of 1∶2 on both sides, and compared the calculated wave surface displacement and harmonic wave amplitude with the experimental data of trapezoidal submerged breakwater in literature, the results show higher coincidence. At the same time, the coincidence degree between the simulated wave surface displacement and the experimental data is more than 0.99,which indicates excellent linear and nonlinear performance of calculation model. The above results show that the model can be used to accurately simulate the propagation and deformation of non-linear waves on submerged breakwaters with slope less than 1∶2.
