NUMERICAL MODELING OF WATER WAVES

by
Dr. Charles L. Mader

SECOND EDITION ISBN - 0-8493-2311-8

CRC Press, Boca Raton, Florida

This second edition of Numerical Modeling of Water Waves describes the technological revolution that has occurred in numerical modeling of water waves during the last decade. A CD-ROM with many of the FORTRAN codes of the numerical methods for solving water wave problems and computer animations of the problems that have been solved using the codes is included with the book. Several PowerPoint presentations describing the modeling results are on the CD-ROM called the NMWW CD-ROM in the rest of the book.

The objective of this book is to describe the numerical methods for modeling water waves that have been developed primarily at the Los Alamos National Laboratory over the last four decades and to describe some examples of the applications of these methods. Some of the applications of the numerical modeling methods were performed while the author was working at the Joint Institute for Marine and Atmospheric Research at the University of Hawaii, some as Mader Consulting Co. research projects, and the rest as a Fellow of the LosAlamos National Laboratory.

Although the two- and three-dimensional numerical methods for modeling water waves had been available in the 1980's for several decades, they had seldom been used. A major obstacle to their use was the need for access to large and expensive computers. By the 1980's, inexpensive personal computers were adequate for many applications of these numerical methods.

In this book, the basic fluid dynamics associated with water waves are described. The common water wave theories are reviewed in Chapter 1. A computer code called WAVE for personal computers that calculates the wave properties for Airy, third-order Stokes, and Laitone solitary gravity waves is available on the NMWW CD-ROM. The incompressible fluid dynamics model used for shallow water, long waves is described in Chapter 2. A computer code for personal computers using the shallow water model is called SWAN and is available on the NMWW CD-ROM. The SWAN code is used to model the 1946, 1960 and 1964 earthquake generated Hilo, Hawaii tsunamis, the 1964 Crescent City, California tsunami and the 1994 underwater landslide generated Skagway, Alaska tsunami.
