Book Description
A method using a digital computer and an incremental plotter for calculating and plotting wave rays is described. Given a grid of depth values, the initial position of a wave ray, and the direction of travel and the period of the wave, successive points along the ray path are calculated. For each point on the path, water depth and bottom slope are estimated from the depth grid by linear interpolation, wave speed and curvature are computed according to classic theory, and the location of the next successive point is approximated by an iteration procedure. The numerical results may be plotted automatically. An example of the results, obtained from an application of the method to Virginia Beach, Virginia, is presented. Unless the bathymetry of an area is unusually smooth, this method calculates and plots wave rays faster than they can be manually constructed. (Author).

Book Description
This book is intended as an introduction to classical water wave theory for the college senior or first year graduate student. The material is self-contained; almost all mathematical and engineering concepts are presented or derived in the text, thus making the book accessible to practicing engineers as well.The book commences with a review of fluid mechanics and basic vector concepts. The formulation and solution of the governing boundary value problem for small amplitude waves are developed and the kinematic and pressure fields for short and long waves are explored. The transformation of waves due to variations in depth and their interactions with structures are derived. Wavemaker theories and the statistics of ocean waves are reviewed. The application of the water particle motions and pressure fields are applied to the calculation of wave forces on small and large objects. Extension of the linear theory results to several nonlinear wave properties is presented. Each chapter concludes with a set of homework problems exercising and sometimes extending the material presented in the chapter. An appendix provides a description of nine experiments which can be performed, with little additional equipment, in most wave tank facilities.

Book Description
This book discusses coastal defense measures, which have not improved in the past few decades, and better alternatives. It emphasizes on the existence of stable bays in coastal geomorphology and their use in coastal stabilization. The conventional measures for saving beaches, such as seawalls, groins, offshore breakwaters, and renourishment, are discussed in detail, followed by an alternative known as headland control. Many types of coast, and the respective defense measures, are discussed, especially for eroding beaches downcoast of harbors with long breakwaters. The formation of offshore bars during storms is examined and the design of stable recreational beaches is demonstrated. Practical design problems are discussed in all cases. Many issues requiring attention in coastal engineering are also outlined.
