Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
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.

Book Description
Structural designs barely consider the dynamic scenario of a well-developed impinging wave hitting the structure. The usual area of focus is on static and stability factors (e.g. drag, inertia, resistive forces related to weight, buoyancy, sliding etc). Even the "Factor of Safety" which is regularly used in designs to account for unknown and/or unforeseen situations which might occur implies a degree of uncertainty about the dynamic scenario of breaking waves in the coastal environment. In the present study the hydrodynamics of a coastal structure-turbulent bore interaction was studied by examination (two-dimensional) of the singular case of a plunging breaking wave forming a well developed turbulent bore which impacted on a model sea wall structure. The turbulent bore impact event was found to display similar characteristics to the impact event of other wave shapes, in particular that of a plunging breaker. Examination of the impact event confirmed the conversion of nearly all horizontal velocity to vertical velocity during the "flip through" event. In accordance with theoretical expectations the location of maximum pressure was found to occur just below the still water level (SWL). Resulting pressure data in the present study consisted of two blunt spikes as opposed to the "church-roof" (high spike) shape seen in other results. The shape of the pressure data was attributed to the following: firstly, to the initial impact of the protruding jet of the breaking wave which causes the first maxima, secondly, to the sensor encountering the bulk of the entrapped air hence causing the drop in pressure between the blunt spikes and lastly, to the inherent hydrostatic pressure combined with the compression of the entrapped air bubbles, by the subsequent forward motion of the water within the wave, which causes the second maxima. The point of maximum pressure was found to always be within the second maxima. Observation of the turbulent bore-structure interaction showed that the consequential maximum pressure was a direct result of the compression of entrapped air by the weight of the water in the wave as it continued forward onto the structure combined with the inherent hydrostatic pressure of the wave. The project was conducted in an attempt to contribute to the vast knowledge of coastal structure-wave interactions and to add to the understanding of the physics and characteristics of breaking waves. Whilst numerous studies and experiments have been carried out on the phenomenon of breaking waves by previous researchers the current project highlights the advent of new equipment and technological advances in existing methods.

Book Description
Several analytical and experimental studies on the highest gravity water wave that can be reflected by a structure, the highest progressive wave in shallow water, and the highest wave that will break on a structure were analyzed. This resulted in diagrams for the selection of the design wave reflected by or breaking on a structure. It was found that the height of the design wave depends on the characteristics of the deepwater wave, the wave reflection coefficient of the structure, the water depth at the structure, and the bottom slope and depth contours seaward of the structure. For the wave reflection coefficients of seawalls and breakwaters, experimental data available were analyzed, and an analytical approach is presented. This analysis resulted in diagrams for the determination of the wave reflection coefficient, which was found to be a function of the wave steepness, the relative depth of water in front of the structure, the angle of wave approach to the structure, and the shape, slope, roughness, and permeability of the structure. Equations, developed to the second order of approximation, for calculating the wave pressures on seawalls and breakwaters caused by waves reflected by the structure are presented. The equations take into account the wave reflection coefficient, thus enabling the design engineer to calculate the wave pressures for totally as well as partially reflected waves. An example illustrating the method of selecting the design wave and calculating the wave pressures is presented. (Author).
