The evaluation of wave run-up on beaches is of significant importance since it is used in different coastal engineering and management applications, including the assessment of beach morphology, the determination of erosion and flooding risk, and the design and maintenance of coastal structures. The main aim of this paper is to present a new method of wave run-up prediction, which is intended to be applicable to the various types of natural beaches. A single formulation was established for beaches, which were categorised as dissipative, reflective and intermediate. This comprehensive parametric run-up model, which included both wave set-up and swash excursion, was specifically developed to represent the wide-ranging conditions experienced in the swash zone in terms of beach conditions. The run-up model included a means to account for obliquely incident waves, varying foreshore sediment characteristics and the infiltration/exfiltration processes during swash events; it also used fitting parameters to account for other site-specific conditions. The novel run-up model produced comparable results to other parametric models, and showed good correlation with laboratory data and limited field data. However, while the model was deemed suitable to be adopted at varying coastal sites, field data are required for implementation to yield meaningful output.

预测天然海滩波浪上升的新方法

海滩上的波浪爬升评估具有重要意义，因为它用于不同的海岸工程和管理应用，包括海滩形态的评估、侵蚀和洪水风险的确定以及海岸结构的设计和维护。本文的主要目的是提出一种新的波浪爬升预测方法，旨在适用于各种类型的天然海滩。为海滩建立了一个单一的公式，分为耗散海滩、反射海滩和中间海滩。这种综合参数化爬升模型包括波浪设置和冲刷偏移，是专门为代表冲刷区在海滩条件方面经历的广泛条件而开发的。启动模型包括考虑倾斜入射波浪、变化的前滩沉积物特征以及冲刷事件期间的渗透/渗出过程的方法；它还使用拟合参数来考虑其他特定地点的条件。新的启动模型产生了与其他参数模型相当的结果，并且与实验室数据和有限的现场数据显示出良好的相关性。然而，虽然该模型被认为适合在不同的沿海地点采用，但实施时需要现场数据才能产生有意义的产出。并与实验室数据和有限的现场数据显示出良好的相关性。然而，虽然该模型被认为适合在不同的沿海地点采用，但实施时需要现场数据才能产生有意义的产出。并与实验室数据和有限的现场数据显示出良好的相关性。然而，虽然该模型被认为适合在不同的沿海地点采用，但实施时需要现场数据才能产生有意义的产出。
