Book Description
Hurricane Bob moved up the US east coast and crossed over southern New England and the Gulf of Maine (with peak marine winds up to 100 mph) on 19-20 August 1991, causing significant damage along the coast and shelf. A three-dimensional fully wave-current coupled Finite-Volume Community Ocean Model (FVCOM) system was developed and applied to simulate and examine the coastal ocean responses to Hurricane Bob, Results from process study-oriented experiments show that wave-current interaction caused a significant change of the current direction and mixing, but had relatively little contribution to the maximum sea level along the coast. Diagnostic analyses suggest that the contribution of hurricane-derived wave-current interaction to the net water flux varies in space and time. the hurricane-induced wave-current interaction could generate strong vertical current shear in the stratified areas, leading to strong offshore transport near the bottom and enhanced water mixing over the continental shelf. Stratification also could result in a significant difference of water currents around islands where the water is not vertically well mixed.

Book Description
Hurricane Bob moved up the U.S. east coast and crossed over southern New England and the Gulf of Maine [with peak marine winds up to 54 m/s (100 mph)] on 19-20 August 1991, causing significant damage along the coast and shelf. A 3-D fully wave-current coupled finite-volume community ocean model system was developed and applied to simulate and examine the coastal ocean responses to Hurricane Bob. Results from process study-oriented experiments showed that the impact of wave-current interaction on surge elevation varied in space and time, more significant over the shelf than inside the inner bays. While sea level change along the coast was mainly driven by the water flux controlled by barotropic dynamics and the vertically integrated highest water transports were essentially the same for cases with and without water stratification, the hurricane-induced wave-current interaction could generate strong vertical current shear in the stratified areas, leading to a strong offshore transport near the bottom and vertical turbulent mixing over the continental shelf. Stratification could also result in a significant difference of water currents around islands where the water is not vertically well mixed.

Book Description
In this Special Issue, seven high-quality papers covering the application and development of many high-end techniques for studies on storm tides, surges, and waves have been published, for instance, the employment of an artificial neural network for predicting coastal freak waves [1]; a reproduction of super typhoon-created extreme waves [2]; a numerical analysis of nonlinear interactions for storm waves, tides, and currents [3]; wave simulation for an island using a circulation–wave coupled model [4]; an analysis of typhoon-induced waves along typhoon tracks in the western North Pacific Ocean [5]; an understanding of how a storm surge prevents or severely restricts aeolian supply [6]; and an investigation of coastal settlements and an assessment of their vulnerability [7].

Book Description
The main task of this study focuses on studying the effect of wave-current interaction on currents, storm surge and inundation as well as effects of depth-induced wave breaking, wind field and current on waves by using numerical models. The results show that it is important to incorporate the wave-current interaction effect into coastal circulation, storm surge and inundation models. At the same time, it should consider effects of depth-induced wave breaking, wind field, currents and sea surface elevation in prediction of waves. Specially, we found that: (1) Depth-induced wave breaking plays an important role in wave field in shallow water areas; (2) To more properly model the hurricane induced wave field, it is important to consider the asymmetric structure of the hurricane wind field, the changes in the hurricane translation time history, and the incorporation background wind field into hurricane wind field; (3) For SWH, it will be decreased when waves propagate in the following current direction. On the other hand, current will increase the SWH when waves propagate countercurrent direction. The change of wave propagation direction after crossing Gulf Stream depends not only on refraction, but also on others (e.g. trap waves effect). (4) It is important to introduce wave-current effects into any storm surge and inundation prediction modeling system. Specially, the consideration of wave-induced wind stress, bottom shear stress, and 3-D radiation stress in storm surge and inundation modeling can significantly improve the correctness of the prediction.

Book Description
The aim of this book is to present modern tidal ideas to those who are not tidal specialists, but for whom some knowledge of tides is involved in their professional or scientific field. These include hydrographers, marine and coastal engineers, geologists who specialize in beach or marine sedimentation processes, and biologists concerned with the ways in which living organisms adapt to the rhythms of the sea. Modern practical studies are concerned with problems of marine transport, coastal erosion and the design of coastal defences against flooding. Interest in mean sea-level changes has recently been focused on the possibility of significant increases over the coming century as a result of global warming. Examples of applications from North America, Europe and other parts of the world are included.

Book Description
This book was published in 2004. The Interaction of Ocean Waves and Wind describes in detail the two-way interaction between wind and ocean waves and shows how ocean waves affect weather forecasting on timescales of 5 to 90 days. Winds generate ocean waves, but at the same time airflow is modified due to the loss of energy and momentum to the waves; thus, momentum loss from the atmosphere to the ocean depends on the state of the waves. This volume discusses ocean wave evolution according to the energy balance equation. An extensive overview of nonlinear transfer is given, and as a by-product the role of four-wave interactions in the generation of extreme events, such as freak waves, is discussed. Effects on ocean circulation are described. Coupled ocean-wave, atmosphere modelling gives improved weather and wave forecasts. This volume will interest ocean wave modellers, physicists and applied mathematicians, and engineers interested in shipping and coastal protection.
