The design and management of coastal engineering, like harbors and coastal defense structures, requires the simulation of hydrodynamic phenomena. This special issue collects five original papers that address state of the art numerical simulations of wave fields and wave-induced velocity fields in coastal areas. The first paper proposes a turbulence model for wave breaking simulation, which is expressed in terms of turbulent kinetic energy and dissipation rate of turbulent kinetic energy (k − e); the proposed turbulence model is a modification of the standard k − e turbulence models. The second paper investigates modalities by which wind interacts with wave motion, modifying the wave propagation dynamic. The third paper proposes a study on waves overtopping over coastal barriers. The fourth paper details the numerical simulation of a tsunami wave that propagates over an artificial reservoir, caused by a landslide that creates a solid mass to detach from the slopes and to slide into the reservoir. The fifth paper examines an application case concerning Cetraro harbor (Italy), which is carried out using three-dimensional numerical simulations of wave motion.

沿海地区波场和洋流的数值模拟

沿海工程的设计和管理，如港口和海防结构，需要模拟水动力现象。本期特刊收集了五篇原始论文，这些论文涉及沿海地区波浪场和波浪诱发速度场的最新数值模拟。第一篇论文提出了一种用于破浪模拟的湍流模型，用湍流动能和湍流动能耗散率(k-e)表示；提议的湍流模型是对标准 k-e 湍流模型的修改。第二篇论文研究了风与波浪运动相互作用的方式，从而改变了波浪的传播动态。第三篇论文提出了一项关于海浪越过海岸屏障的研究。第四篇论文详细介绍了在人工水库上传播的海啸波的数值模拟，这是由山体滑坡引起的，产生的固体物质从斜坡上脱离并滑入水库。第 5 篇论文研究了一个有关 Cetraro 港口（意大利）的应用案例，该案例是使用波浪运动的三维数值模拟进行的。
