植被对水波传播有重要影响，基于抛物型缓坡方程建立了近岸水波在植被场中传播的模型，模型中考虑了波浪破碎引起的折射、绕射和波浪能量耗散以及植被效应，并对模型进行了验证，分析了植被对水波传播的影响。数值结果表明，植被对近岸水波传播有重要影响，波高随植物密度和植物高度的增加而衰减，植被引起的水波能量耗散与波浪周期有关。
The vegetation has important impact on the propagation of water waves.The model for coastal water wave propagation in vegetation field was built based on the parabolic mild slope equation,in which the refraction,diffraction and wave energy dissipation due to wave breaking and vegetation effect were considered.The model was validated,and the vegetation impacts on water wave propagation were also analyzed by the model.It was shown by numerical results that the vegetation has important impacts on coastal water wave propagation,and the wave height attenuated with the increase of plant density,as well as plant height,and the water wave energy dissipation due to vegetation was also related to wave period.
