Analyses are presented of two-dimensional laboratory measurements of the forces induced by breaking waves on a vertical barrier placed on a plane with a one-to-ten slope. When a wave breaks on the barrier its momentum, calculated by use of the solitary wave theory, is found to be in substantial agreement with the impulse (force times time) on the barrier, measured from the initial impact to the time of momentum reversed (maximum of rise).

Analyses are presented of two-dimensional laboratory measurements of the forces induced by breaking waves on a vertical barrier placed on a plane with a one-to-ten slope. The deepwater wave heights ranged from 0.2 to 0.6 foot and their periods ranged from 1.9 to 3.3 seconds. The ratio between the depth of water in front of the barrier and the deepwater wave length was approximately 0.0115. The forces on the barrier in this study are usually characterized by a peak, which occurs immediately after the initial impact. The impulse of the peak is usually a small percentage of the cumulative impulse up to the time of momentum reversal. After this short-duration peak, the force decreases exponentially until after an appreciable part of the wave period - about one-sixth, depending on the wave steepness - when it rises again to a (second) maximum which occurs at the time of momentum reversal. This maximum in the force is approximately equal to the average force from the time of initial impact to the time of this maximum of rise (momentum reversal). (Author).

Weggel's (1981) method for calculating water wave forces on smooth, vertical walls is experimentally verified for an intermediate-length, non-breaking wave which approaches the structure at several small angles of incidence. Mach-stem reflection data is verified with respect to results from Perroud (1957) and Nielsen (1962). Cnoidal wave theory is applied to measured wave data to create pressure distributions, which are verified by measured pressure values. The cnoidal pressure distributions are graphically integrated to produce force values which are compared to values generated by Weggel's method. (Author).

The purpose of the paper is to examine theories and data related to wave pressures induced on a vertical seawall by the impingement of water waves which have broken seaward of the wall. The report compares the six articles found by the writer, which relate directly to this subject. Each of the independent studies is reviewed briefly in regard to its purpose, test procedure, theory proposed, test results and conclusions. Comparison of data and theory of the studies is then made.

The present edition, with new title Coastal Engineering, is the enlarged and updated volume of the book origin-ally published under the title Coastal Hydrodynamics in 2012. The book provides an overview of world population and ocean resources, natural threats and man-made hazards, and their impact on coastal environment. It discusses the fundamentals of wind, waves, tides and fluid flow and describes commonly adopted wave theories in coastal engineering. The text explains the methods for estimating wave forces on coastal structures, procedures for the analysis of wave data, and sediment transport. Apart from the estimation of beach profile evolution and shoreline change, the book discusses key aspects related to the design of different coastal structures. NEW TO THE SECOND EDITION • Includes two new chapters on Beach Profile and Shoreline Evolution and Design of Breakwaters and Coastal Protective Structures • Colour photographs are appended at the end of the book KEY FEATURES • Worked-out examples will benefit the reader to understand and solve variety of coastal engineering problems. • Exercises given at the end of each chapter would benefit the reader to get exposed to a variety of practical problems related to coastal engineering. TARGET AUDIENCE • B.Tech./M.Tech. (Ocean Engineering/ Marine Engineering)
