Case studies and worked-out examples illustrate different concepts and methods Offers practical methods for Data Selection and Pre-Processing Provides simplified prediction tools for practical applications

This unique compendium introduces the field of numerical modelling of water waves. The topics included the most widely used water wave modelling approaches, presented in increasing order of complexity and categorized into phase-averaged and phase-resolving at the highest level.A comprehensive state-of-the-art review is provided for each chapter, comprising the historical development of the method, the most relevant models and their practical applications. A full description on the method's underlying assumptions and limitations are also provided. The final chapter features coupling among different models, outlining the different types of implementations, highlighting their pros and cons, and providing numerous relevant examples for full context.The useful reference text benefits professionals, researchers, academics, graduate and undergraduate students in wave mechanics in general and coastal and ocean engineering in particular.

Modelling large-scale wave fields and their interaction with coastal and offshore structures has become much more feasible over the last two decades with increases in computer speeds. Wave modelling can be viewed as an extension of wave theory, a mature and widely published field, applied to practical engineering through the use of computer tools. Information about the various wave models which have been developed is often widely scattered in the literature, and consequently this is one of the first books devoted to wave models and their applications. At the core of the book is an introduction to various types of wave models. For each model, the theoretical assumptions, the application range, and the advantages and limitations are elaborated. The combined use of different wave models from large-scale to local-scale is highlighted with a detailed discussion of the application and matching of boundary conditions. At the same time the book provides a grounding in hydrodynamics, wave theory, and numerical methods which underlie wave modelling. It presents the theoretical background and also shows how to use these models for achieving different engineering tasks, illustrated and reinforced with case study examples.

Numerical Modeling of Water Waves, Second Edition covers all aspects of this subject, from the basic fluid dynamics and the simplest models to the latest and most complex, including the first-ever description of techniques for modeling wave generation by explosions, projectile impacts, asteroids, and impact landslides. The book comes packaged with

Breakwaters are widely used to provide economical protection from waves in harbors and marinas. Also, the submerged breakwaters were extensively adopted to reduce wave motion in front of vertical wall breakwaters. In this study, the flow pattern is numerically simulated using FLOW-3D software. To model the flow field turbulence, the standard and RNG turbulence models are used. According the numerical results, the standard turbulence model had more accuracy than RNG turbulence model. Also, the Volume of Fluid is applied for modeling the variations of flow free surface. To validate the numerical results, Li and Fleming (2001) study results are used. According to numerical simulation results, the numerical model predicted the variation of free surface with reasonable accuracy. For example, the MAPE is computed 11.808% for numerical model. Also, the variations of other hydraulic and hydrodynamic parameters were examined. For instance, the maximum flow field pressure before and after break were calculated 4763 and 4923 pa, respectively.
