外文摘要：This study aims to investigate the influence of submerged breakwater slopes on wave-current propagation characteristics under various wave-current conditions using a numerical wave tank model based on the finite volume method. The propagation and deformation of wave-current over submerged breakwaters are systematically calculated, with seaward slopes, incident wave amplitudes, and current velocities taken as key variables. Emphasis is placed on analyzing the free surface morphology and the corresponding spectral variation characteristics; meanwhile, the influence of slopes on wave-current propagation is explored in depth through the dimensionless analysis of free surface elevations. The findings indicate that the nonlinear deformation of the free surface during wave-current propagation is significantly affected by seaward slopes, wave amplitudes, and current velocities. The dimensionless analysis of the free surface elevations indicates that under wave-current coupling conditions with low velocities, the attenuation effect of seaward slopes on free surface elevation amplitudes can be neglected. However, as the current velocity increases, the influence of slope variations on free surface morphology and the peak-to-trough differences of free surface elevations becomes more pronounced. The capacity of the submerged breakwater to attenuate free surface amplitude strengthens as the wave amplitude increases.
