Book Description
This report represents a review and conclusion of several studies conducted at the University of Delaware with the aim of providing numerical model for calculating nearshore wave-induces currents and mean water level fluctuations. The purpose of constructing a numerical model rests on the need to extend our predictive capabilities into situations which lie beyond the scope of analytic methods. In the end, all numerical models, as well as analytical formulations, are limited in scope by the simplifying assumptions incorporated in their theoretical framework; in this regard, the present models represent an attempt to extend present analytic treatments to the case of a complex topography in two dimensions. The models do not consider the associated sediment transport problem, although this capability can be added. Also, the models require that the incident wave field be regarded as monochromatic, or, after some model modifications, narrow banded enough to be represented as a modulated wave train at a single carrier frequency.

Book Description
Ocean wave propagation is heavily affected by bathymetric variation, particularly in the nearshore areas. In this report, the theoretical basis behind the mild slope equation, which is often used for modeling wave propagation, is discussed. In particular, the theory and technical details of the models REF/DIF1, REF/DIF-S, and RCPWAVE are defined. (REF/DIF-S is an irregular wave version of REF/DIF1.) Two different modifications of the mild slope equation that simplify the modeling of wave propagation for general areas: the parabolic approximation, which is used in the model REF/DIF1 and REF/DIF-S; and the eikonal-transport equations, used in RCPWAVE are examined. The consequences of using either modification is also discussed. Incorporation of relevant physical effects (e.g., wave breaking, bottom friction, etc.) that affect wave propagation in the nearshore area is illustrated.

Numerical Modeling of Water Waves

Category : Technology & Engineering

Pages : 499
Book Description
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.
