Special Issue Information

Dear Colleagues,

Wind waves and swell play a decisive role in a number of oceanic and coastal issues, including the design of coastal and port protection structures, the exploitation of marine renewable energies, sediment transport and morphodynamic changes, the occurrence of extreme waves (rogue waves), the transport and dispersion of pollutants, etc.

Many physical processes affect ocean wave fields from the wind generation area in deep water to the shore or to coastal structures. During their propagation, over potentially long distances, wave trains are modified by interaction with the atmosphere, nonlinear wave–wave interactions, dissipation by white-capping, bottom friction or breaking, shoaling, refraction, wave–bottom interactions, as well as diffraction and reflection in the presence of islands, breakwaters, shoals or underwater landforms. Wave fields also interact with ambient flows, due to the tide, a river outlet, or ocean circulation currents.

The development of mathematical models capable of representing all these physical processes on waves, or at least the dominant phenomena, remains a subject of research that is still widely open. Different types of mathematical models exist, based on a phase-resolving or phase-averaged approach. These models introduce more or less simplified representations of the real sea-states, more or less strong approximations on the dispersive and nonlinear properties of waves, and the representation of certain physical processes or interactions with an ambient current field is more or less simplified or parameterized. Regarding the numerical methods, a range of techniques are employed to solve these models, e.g., finite difference, finite volume, finite element, and spectral methods.

The purpose of this Special Issue is to present the most recent advances in the field of mathematical modeling and numerical simulation of water waves, from the ocean domain to the coastal and port domains. Different spatial and temporal scales will be addressed, namely, oceanic domain, nearshore domain, coastal and coastal zone, and harbor domain. The presentation of novel mathematical models is encouraged, as well as the development of efficient and accurate numerical methods to simulate these models, with applications to real cases from the ocean to the shore.

Coastal plants can significantly dissipate water wave energy and services as a part of shoreline protection. Using plants as a natural buffer from wave impacts remains an attractive possibility. In this paper, we present a numerical investigation on the effects of the emerged vegetation on non-breaking, breaking and broken wave propagation through vegetation over flat and sloping beds using the Reynolds-average Navier-Stokes (RANS) equations coupled with a volume of fluid (VOF) surface capturing method. The multiphase two-equation k-ω SST turbulence model is adopted to simulate wave breaking and takes into account the effects enhanced by vegetation. The numerical model is validated with existing data from several laboratory experiments. The sensitivities of wave height evolution due to wave conditions and vegetation characteristics with variable bathymetry have been investigated. The results show good agreement with measured data. For non-breaking waves, the wave reflection due to the vegetation can increase wave height in front of the vegetation. For breaking waves, it is shown that the wave breaking behavior can be different when the vegetation is in the surf zone. The wave breaking point is slightly earlier and the wave height at the breaking point is smaller with the vegetation. For broken waves, the vegetation has little effect on the wave height before the breaking point. Meanwhile, the inertia force is important within denser vegetation and is intended to decrease the wave damping of the vegetation. Overall, the present model has good performance in simulating non-breaking, breaking and broken wave interaction with the emerged vegetation and can achieve a better understanding of wave propagation over the emerged vegetation.
