外文摘要：Vegetation, that can mitigate the effects of natural disasters by reducing the intensity of storm surges and waves, plays a vital role in coastal protection. This study aims to thoroughly investigate the wave heights impact on the wave attenuation of rigid vegetation under extreme waves based on a SPH model. To validate the model, the numerical wave heights are examined in relation to the exact solutions and experimental data. With a maximum L2 error of 0.024 and maximum relative error of 4.5 %, the numerical results correspond well with the exact solutions. The transmitted and reflected wave peaks decrease as the Incident Wave Height (IWH) decreases. The transmission coefficient decreases while the dissipation and reflection coefficients increase with the IWH increases. The maximum values of these coefficients are 0.617, 0.530, and 0.774, respectively, and the minimum values are 0.347, 0.458, and 0.64. The relatively high dissipation coefficient indicates significant energy dissipation during the interaction involving plants and solitary waves. The standard deviations of the reflection, dissipation, and transmission coefficient are 0.03, 0.05, and 0.10, respectively, indicating that the influence of IWH on these coefficients increase in sequence. Polynomial fitting gives precise empirical quadratic functions with determination coefficients R2 = 0.991, 0.976, and 0.995 for the three coefficients.
