Book Description
A research program is underway at NRL to develop new methods for the numerical calculation of surface wave effects on marine structures. Sufficient progress has been made with one particular NRL-developed computer code, SPLISH, to demonstrate the attractiveness of numerical calculations for problems such as the wave flow over a submerged structure. A brief description is given in this report of the numerical method and of some recent computational results. The present results demonstrate that realistic time-varying local flow fields, pressures and forces on a near structure such as the half-cylinder on the ocean floor can be determined from numerical calculations for certain conditions. Comparisons between the numerical results from SPLISH and recent linear and fifth-order solutions for wave flow over a bottom seated half-cylinder show good agreement as do comparisons between the numerical results and experiments in a wave channel.

Book Description
The increase in exploration and exploitation of ocean resources, maritime trade and ocean energy have led to development of new concepts in the study of coastal and marine structures. These developments necessitate comprehensive and in-depth knowledge of ocean wave behavior in the offshore as well as in the nearshore, such as the phenomena of wave generation, propagation, deformation and its effects, which help to enlighten our understanding of its influence on coastal and offshore structures.Ocean Wave Dynamics for Coastal and Marine Structures is a recommended textbook for students and researchers in ocean sciences, engineering and related topics. It offers application of theoretical formulae to practical relevance through problem solving. This book will also be invaluable for professionals in ports, offshore and marine industries as well as consulting companies.

Book Description
Wave Mechanics and Wave Loads on Marine Structures provides a new perspective on the calculation of wave forces on ocean structures, unifying the deterministic and probabilistic approaches to wave theory and combining the methods used in field and experimental measurement.Presenting his quasi-determinism (QD) theory and approach of using small-scale field experiments (SSFEs), author Paolo Boccotti simplifies the findings and techniques honed in his ground-breaking work to provide engineers and researchers with practical new methods of analysis. Including numerous worked examples and case studies, Wave Mechanics and Wave Loads on Marine Structures also discusses and provides useful FORTRAN programs, including a subroutine for calculating particle velocity and acceleration in wave groups, and programs for calculating wave loads on several kinds of structures. Solves the conceptual separation of deterministic and stochastic approaches to wave theory seen in other resources through the application of quasi-determinism (QD) theory Combines the distinct experimental activities of field measurements and wave tank experiment using small-scale field experiments (SSFEs) Simplifies and applies the ground-breaking work and techniques of this leading expert in wave theory and marine construction

Book Description
This book focuses on: (1) the physics of the fundamental dynamics of fluids and of semi-immersed Lagrangian solid bodies that are responding to wave-induced loads; (2) the scaling of dimensional equations and boundary value problems in order to determine a small dimensionless parameter ε that may be applied to linearize the equations and the boundary value problems so as to obtain a linear system; (3) the replacement of differential and integral calculus with algebraic equations that require only algebraic substitutions instead of differentiations and integrations; and (4) the importance of comparing numerical and analytical computations with data from laboratories and/or nature.

Book Description
This book is intended as a handbook for professionals and researchers in the areas of Physical Oceanography, Ocean and Coastal Engineering and as a text for graduate students in these fields. It presents a comprehensive study on surface ocean waves induced by wind, including basic mathematical principles, physical description of the observed phenomena, practical forecasting techniques of various wave parameters and applications in ocean and coastal engineering, all from the probabilistic and spectral points of view. The book commences with a description of mechanisms of surface wave generation by wind and its modern modeling techniques. The stochastic and probabilistic terminology is introduced and the basic statistical and spectral properties of ocean waves are developed and discussed in detail. The bulk of material deals with the prediction techniques for waves in deep and coastal waters for simple and complex ocean basins and complex bathymetry. The various prediction methods, currently used in oceanography and ocean engineering, are described and the examples of practical calculations illustrate the basic text. An appendix provides a description of the modern methods of wave measurement, including the remote sensing techniques. Also the wave simulation methods and random data analysis techniques are discussed. In the book a lot of discoveries of the Russian and East European scientists, largely unknown in the Western literature due to the language barrier, are referred to.

Book Description
This book is an expanded version of The Applied Dynamics of Ocean Surface Waves. It presents theoretical topics on ocean wave dynamics, including basic principles and applications in coastal and offshore engineering as well as coastal oceanography. Advanced analytical and numerical techniques are applied, such as singular perturbations. In this expanded edition, two chapters on recent developments have been added: one is on multiple scattering by periodic or random bathymetry, and the other is on Zakharov's theory of broad spectrum wave fields. New sections include topics on infragravity waves, upstream solitons, Venice storm gates, etc. In addition, there are many new exercises. Theory and Applications of Ocean Surface Waves will be invaluable for graduate students and researchers in coastal and ocean engineering, geophysical fluid dynamicists interested in water waves, and theoretical scientists and applied mathematicians wishing to develop new techniques for challenging problems or to apply techniques existing elsewhere.

Book Description
New Edition: Ocean Surface Waves: Their Physics and Prediction (3rd Edition)The book is an extended and updated edition of the book published in 1996 under the same title (World Scientific, ISBN 9810216866). It contains a very comprehensive and extensive study on surface ocean waves induced by wind, earthquakes and possible landslides and asteroids impacts. The basic mathematical principles, physical description of the observed phenomena, practical forecasting techniques of the various wave parameters and extended application in ocean and coastal engineering, are discussed from the stochastic point of view.All chapters were completely rewritten and supplemented with many new discoveries which were published since the first edition in 1996. In particular, new chapters are added on very interesting and contemporary topics such as: wave breaking mechanisms in deep- and shallow water, freak waves, tsunami, water circulation in porous sea bottom induced by surface waves, and waves propagation through mangrove forests.In terms of numerical modeling, the state of the art of the modern methodology of wave prediction models WAM and SWAN, as well as of the high sophisticated satellite methods of waves measurement and modern methods of signal processing, including wavelets approach and Hilbert Transform approach are presented. The book is supplemented with an extended list of relevant and extended, contemporary bibliography, subject index and author index.
