【摘要】 通过在Boussinesq水波模型中引入拖曳应力项来考虑植被对波浪的衰减作用,建立了波浪在近岸刚性植被水域传播运动的数值模型。在对模型进行验证的基础上,模拟分析了植被特征参数与入射波要素对波浪传播运动的影响。数值模拟结果表明,波浪在近岸植被区传播时,随着植被密度和植被淹没高度的增加,波浪传播中波高衰减率增大、波能损耗率增大;随着入射波高的增加,波浪传播中波高衰减率增大、波能损耗率增大。更多还原

【Abstract】 The numerical model for wave propagation in rigid vegetation water was developed based on Boussinesq equation,in which the drag force due to vegetation was added.The model was verified by comparing the numerical and experimental results. The model was used to test the effects of vegetation parameters as well as the incident wave parameters on wave propagation.The numerical results indicates that the ratio of wave height attention and wave energy attention increase with the increasing of plant density and plant diameter,as well as the incident wave height.更多还原
