植被对传播水波的减振作用已被许多研究人员所研究。本文通过数值模拟研究了植被减振对孤立水波爬升的影响。该数值模式是基于Morison的植物诱导惯性应力和阻力应力公式在非线性浅水方程中的实现。数值模型在笛卡尔剖分网格上用有限体积法求解。通过与试验结果的对比，验证了数值方案的准确性和模型中植被项的影响。然后将该模型应用于模拟孤立波在有植被的平坦斜坡上的传播。通过对不同植被类型的数值计算结果的比较，研究了孤立波爬升对植物高度、直径和树干密度的敏感性。数值结果表明，植被能有效地降低孤波传播速度，且随着植物水中高度、直径和茎密度的增加，孤波爬升速度减小。
Vegetation damping effects on propagating water waves have been investigated by many researchers. This paper investigates the effects of damping due to vegetation on solitary water wave run-up via numerical simulation. The numerical model is based on an implementation of Morison's formulation for vegetation induced inertia and drag stresses in the nonlinear shallow water equations. The numerical model is solved via a finite volume method on a Cartesian cut cell mesh. The accuracy of the numerical scheme and the effects of the vegetation terms in the present model are validated by comparison with experiment results. The model is then applied to simulate a solitary wave propagating on a plane slope with vegetation. The sensitivity of solitary wave run-up to plant height, diameter and stem density is investigated by comparison of the numerical results for different patterns of vegetation. The numerical results show that vegetation can effectively reduce solitary wave propagation velocity and that solitary wave run-up is decreased with increase of plant height in water and also diameter and stem density.
