Coastal and ocean processes are heavily influenced by the kinematics of waves. In order to understand these processes, researchers place a variety of instruments in the sea in an attempt to measure the waves. These instruments all measure a small set of physical quantities at a small number of locations. The balance of the kinematics must be predicted through analysis of the measured records. Most of the currently used methods of analysis rely on the superposition of linear waves to recreate complex seas. These methods are compromised by linearizing approximations to the free surface boundary conditions. Fidelity in the interpretation of wave measurements is enhanced by insisting that the analysis satisfies the full nonlinear free surface boundary conditions. The Local Fourier method for irregular wave kinematics is introduced and expanded to include the interpretation of records from arrays of instruments. It is a local method, in that a separate solution is sought that fits the measured record(s) in a small local window in time, rather than attempting to find a single solution for a large segment of the record. Each window solution satisfies the full set of governing equations for gravity waves, including the nonlinear free surface boundary conditions. The solution in each window is a potential function whose form is based upon a Stokes style expansion for intersecting waves. The parameters of the potential function are found by a nonlinear optimization that seeks the solution that matches the measured record and satisfies the full free surface boundary conditions.

Water wave kinematics is a central field of study in ocean and coastal engineering. The wave forces on structures as well as sand erosion both on coastlines and in the ocean are to a large extent governed by the local distribution of velocities and accelerations of the water particles. Our knowledge of waves has generally been derived from measurements of the water surface elevations. The reason for this is that the surface elevations have been of primary interest and fairly cheap and reliable instruments have been developed for such measurements. The water wave kinematics has then been derived from the surface elevation information by various theories. However. the different theories for the calculation of water particle velocities and acceleration have turned out to give significant differences in the calculated responses of structures. In recent years new measurement techniques have made it possible to make accurate velocity measurements. Hence. the editors deemed it to be useful to bring together a group of experts working actively as researchers in the field of water wave kinematics. These experts included theoreticians as well as experimentalists on wave kinematics. It was also deemed useful to include experts on the response of structures to have their views from a structural engineering point of view on what information is really needed on water wave kinematics.

Hurricanes are one of the most adverse aspects of the ocean environment, with the potential to cause a disastrous event for marine systems in the ocean. Hurricane Generated Seas is an invaluable reference for all involved in the field of naval, ocean and coastal engineering. The work clarifies hurricane generated sea conditions necessary for the design and operation of marine systems in a seaway, and provides information for the protection of near shore / onshore structures and the environment at the time of hurricane landing. - Reveals Information vital for avoidance of disastrous events experienced by ships and offshore structures - Includes detailed analysis of hurricane sea wave data obtained by buoys

A Users Guide to Hydraulic Modelling and Experimentation provides a systematic, comprehensive summary of the progress made through HYDRALAB III . The book combines the expertise of many of the leading hydraulic experimentalists in Europe and identifies current best practice for carrying out state-of-the-art, modern laboratory investigations. In addition it gives an inventory and reviews recent advances in instrumentation and equipment that drive present and new developments in the subject. The Guide concentrates on four core areas – waves, breakwaters, sediments and the relatively-new (but rapidly-developing) cross-disciplinary area of hydrodynamics/ecology. Progress made through the ‘CoMIBBS’ component of HYDRALAB III provides the material for a chapter focussed on guidance, principles and practice for composite modelling. There is detailed consideration of scaling and the degree of relevance of laboratory/physical modelling approaches for specific contexts included in each of the individual chapters. The Guide includes outputs from the workshops and several of the innovative transnational access projects that have been supported within HYDRALAB III, as well as the focussed joint research activities SANDS and CoMIBBS. Its primary purpose is to serve as a shared resource to disseminate the outstanding advances achieved within HYDRALAB III but, even more than this, it is a tribute to the human and institutional collaborations that led to and sustained the research advances, the human relationships that were strengthened and initiated through joint participation in the Programme, and the training opportunities that participation provided to the many young researchers engaged in the projects.

Sixty peer-reviewed papers presented at the April-May 1998 symposium focus on the exchange of knowledge between academics and practitioners on subjects of crucial to the successful design of offshore and coastal structures and to the study of pollutant transport in ocean waters. The papers present recent advances in the understanding, measurement, and prediction of wave kinematics, wave dynamics, and wave loads acting on offshore and coastal structures, and include new theories, models, statistics, and measurements.

Science and Engineering of Freak Waves provides a holistic and interdisciplinary view of extreme ocean waves for both scientific and engineering applications. Readers will learn the fundamental theory of extreme waves and the implications they have on coastal structures and methods of prediction through chapters that review the definitions of extreme waves, their history and other important observations. After this, the book's authors describe the theory and modeling of extreme waves that occur in various situations. Final sections provide examples of the application of extreme wave research results to various engineering designs are presented. This book provides a comprehensive overview of the current status of our understandings on freak/rogue waves, the science of extreme waves, prediction, and their engineering applications. As such, it is a must read for physical oceanographers looking for a better understanding of prediction models and the history of these waves, and engineers looking for more information on preparedness and implications for offshore structures and shipping. - Presents the history of extreme wave research, including field observations, experiments, numerical modeling, data assimilation and theory - Includes numerous freak wave prediction systems and explains when and how they should be used - Showcases global case studies where prediction has or could have been used to increase preparedness - Provides sample codes so that readers can easily apply these methods to their own science
