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.

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.

A large number of existing state-of-the-art numerical models were reviewed for the purpose of selecting an efficient model to be used for routine analysis of wave attenuation and mooring forces assiciated with a floating breadwater. The models reviewed came from five basic categories: Eigen Function Expansion Models, Green Function Models, Hybid Green Function Models, Finite Element Models and other models. The critical parameters in the selection process were (a) computational efficiency; (b) ability to accommodate three-dimensional spectra as the input wave; and (c) versatility relative to breakwater geometry and water depths. Based on these criteria, a Hybrid Green Function Model was selected as the optimum numerical model, followed by a Green Function Model. Recommendations are presented which include the acquisition and adaptation of the selected model and the comparison of output with corresponding prototype data. The two-dimensional model also was recommended for use as a fast diagnostic assessment tool. During test runs, investigators should pay special attention to the development of optimum procedures for determining the mooring force. Results of prototype tests performed by the Coastal Engineering Research Center and the Japanese Ministry of Transport can be used to support test runs.

This book discusses the numerical simulation of water waves, which combines mathematical theories and modern techniques of numerical simulation to solve the problems associated with waves in coastal, ocean, and environmental engineering. Bridging the gap between practical mathematics and engineering, the book describes wave mechanics, establishment of mathematical wave models, modern numerical simulation techniques, and applications of numerical models in engineering. It also explores environmental issues related to water waves in coastal regions, such as pollutant and sediment transport, and introduces numerical wave flumes and wave basins. The material is self-contained, with numerous illustrations and tables, and most of the mathematical and engineering concepts are presented or derived in the text. The book is intended for researchers, graduate students and engineers in the fields of hydraulic, coastal, ocean and environmental engineering with a background in fluid mechanics and numerical simulation methods.
