在这项工作中，波的植被场的转换模型。该公式包括波浪阻尼和波浪破碎植被场在不同的深度。基于拖曳力的非线性公式，考虑植被场的几何和物理特性，可以模拟单色波或不规则波的变换。该模型依赖于一个单一的参数类似的阻力系数，这是参数化的局部Keulegan-Carpenter数的函数为一个特定类型的植物。鉴于这种参数化，确定与实验室实验为每种植物类型，该模型是能够再现的均方根波高转换实验数据中观察到的合理的准确性。(C)2004 Elsevier B.V保留所有权利。
In this work, a model for wave transformation on vegetation fields is presented. The formulation includes wave damping and wave breaking over vegetation fields at variable depths. Based on a nonlinear formulation of the drag force, either the transformation of monochromatic waves or irregular waves can be modelled considering geometric and physical characteristics of the vegetation field. The model depends on a single parameter similar to the drag coefficient, which is parameterized as a function of the local Keulegan-Carpenter number for a specific type of plant. Given this parameterization, determined with laboratory experiments for each plant type, the model is able to reproduce the root-mean-square wave height transformation observed in experimental data with reasonable accuracy.
