This book is a useful source of ideas and information for scientists whose work involves understanding and modelling turbulent flows with free surfaces. It has the following merits: (1) It provides a framework for developing the analysis of this field, which, although important, has received only limited study; (2) It recognizes the importance of the two-phase nature of strongly disturbed free surface flows, with both natural and technological applications; (3) It suggests possible lines of future research (especially experimental) to quantify the characteristics of flow regimes which are mainly known qualitatively at present.

Free-surface flow (or wave) interaction with vegetation is a complex subject. In order to understand the underlying physical processes either physical experiments or numerical simulations, or ideally in complement, can be employed. Both approaches face lots of challenges. For example in experiments, the research question is how to scale-down appropriately the large-scale physics and how to interpret the experimental data. In numerical simulations, how to approximate numerically the complex wave-multiple rigid or flexible structures (vegetal stems) including the resolution of turbulence at all spatial and temporal scales.This book reviews the state of the art of the research in the area of wave-vegetation interaction for coastal applications using numerical and experimental approaches. The reference text will be useful to students, early-career researchers, teachers and practicing engineers in the field of ocean engineering, civil engineering and climate change.
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.

Comprising the Proceedings of the International Workshop on State-of-the-Art Hydraulic Engineering held in Bari, Italy on 16-19 February 2004, this volume presents an in-depth investigation of the energy loss of skimming flows under a range of discharges, step and dam heights, and channel slopes. Including a wealth of information, the volume is div
Most of the Earth's surface is covered by water. Many aspects of our everyday lives and activities may be affected by water waves in some way. Sometimes, the waves can cause disaster. One of the examples was the tsunami that occurred in the Indian Ocean on 26 December 2004. This indicates how important it is for us to fully understand water waves, in particular the very large ones. One way to do so is to perform numerical simulation based on the nonlinear theory. Considerable research advances have been made in this area over the past decade by developing various numerical methods and applying them to emerging problems: however, until now there has been no comprehensive book to reflect these advances. This unique volume aims to bridge this gap.

This book provides a comprehensive description of the latest theory-supported numerical technologies, as well as scientific and engineering applications for water surface waves. Its contents are crafted to cater to a step-by-step learning of computational wave dynamics and ocean wave modeling. It provides a comprehensive description from underlying theories of free-surface flows, to practical computational applications for coastal and ocean engineering on the basis of computational fluid dynamics (CFD).The text may be used as a textbook for advanced undergraduate students and graduate students to understand the theoretical background of wave computations, and the recent progress of computational techniques for free-surface and interfacial flows, such as Volume of Fluid (VOF), Constrained Interpolation Profile (CIP), Lagrangian Particle (SPH, MPS), Distinct Element (DEM) and Euler-Lagrange Hybrid Methods.It is also suitable for researchers and engineers who wish to apply CFD techniques to ocean modeling and practical coastal problems involving sediment transport, wave-structure interaction and surf zone flows.
