近岸结构物（如平行海岸防波堤）越浪可显著改变结构物周围的水流环流和沉积物输运模式，进而影响近岸地区连岛和凸起的形成。本文介绍了一个波浪越浪模块到现有的深度平均海岸形态模式：COAST 2D和模型应用程序的实施，调查一组海岸平行防波堤周围的水动力学和形态动力学的波浪越浪的影响。对一系列的实验室条件下，该模型的流体动力学方面进行了验证。然后，该模型被应用到一个研究网站在海帕林，诺福克，英国，其中9个海岸平行分段防波堤，包括4个表面穿透和5个低顶防波堤，在2006年11月的风暴条件。模型结果与实验室数据和现场测量进行了比较，显示出良好的协议的流体动力学和形态变化。进一步分析了越浪对近岸水动力和地形动力的影响，结果表明，在风暴潮和大潮汐条件下，越浪对这种复杂防波堤方案的近岸环流、泥沙输移以及由此产生的地形变化有着重要的影响。结果表明，包括在建模近岸形态动力学与沿海结构的存在下，越浪的重要性。
Wave overtopping nearshore coastal structures, such as shore-parallel breakwaters, can significantly alter the current circulation and sediment transport patterns around the structures, which in turn affects the formation of tombolos and salients in the nearshore area. This paper describes the implementation of a wave overtopping module into an existing depth-averaged coastal morphological mode: COAST2D and model applications to investigate the effect of wave overtopping on the hydrodynamics and morphodynamics around a group of shore-parallel breakwaters. The hydrodynamic aspects of the model were validated against a series of laboratory conditions. The model was then applied to a study site at Sea Palling, Norfolk, UK, where 9 shore-parallel segmented breakwaters including 4 surface-piercing and 5 low-crested breakwaters are present, for the storm conditions in Nov 2006. The model results were compared with laboratory data and field measurements, showing a good agreement on both hydrodynamics and morphological changes. Further analysis of wave overtopping effect on the nearshore hydrodynamics and morphodynamics reveals that wave overtopping has significant impacts on the nearshore circulation, sediment transport and the resulting morphological changes within such a complex breakwater scheme under the storm and macro-tide conditions. The results indicate the importance of including the wave overtopping in modelling nearshore morphodynamics with the presence of coastal structures.
