亨特方程提供了一种估算破碎波爬高的简单方法。然而,破碎波也会引起斜坡上的立波。亨特方程的修改主张占波设置的存在。模型试验的数据提供了对修改的支持,这些试验涉及随机波接近1:5、1:10、1:20和1:30的光滑、不可渗透的斜坡。给出了修正方程中使用的系数,这些系数允许估计显著的助跑和其他特征值。
Hunt’s equation provides a simple means of estimating the runup of breaking waves. However, breaking waves also induce setup on a slope. A modification to Hunt’s equation is advocated which accounts for the presence of wave setup. Support for the modification is provided by data from model tests involving random waves approaching smooth, impermeable slopes of 1:5, 1:10, 1:20, and 1:30. Coefficients to be used in the modified equation are given which allow the significant runup and other characteristic values to be estimated.
