Book Description
A finite difference model for predicting the nearshore circulation due to wind and waves is presented which attempts to solve the same problem as an earlier model created by Birkemeier and Dalrymple (1975). Their model iteratively solved the linear set of conservation equations of both mass and momentum, which were time averaged (over one wave period) and depth integrated, for mean velocities and free surface displacements. The wave characteristics used in the momentum equations were found using the wave refraction and shoaling routines, including wave-current interaction, developed by Noda, et al. (1974). The model also included a linear bottom friction formulation as well as a surface wind stress capability. The present model discussed herein includes the addition of convective accelerations, horizontal mixing and a quadratic bottom friction term in the conservation of momentum equations. This bottom friction term is 'exact' in the sense that it includes the velocity vectors due to both mean and wave-induced currents. The model is applied to the cases of a single wave train impinging on a plane beach, a barred profile, and a bottom with a periodically spaced rip channel.

Book Description
Simulating Nearshore Environments provides computer procedures that realistically represent nearshore processes and supplement or replace trial and error methodology. The procedures simulate transport by waves and fluvial processes on beaches and deltas at various scales. They will aid coastal engineers, oceanographers and sedimentary geologists who focus on both modern and ancient nearshore deposits. How do you simulate nearshore processes using a computer? Can evolving deltaic and coastal environments be simulated realistically by mathematically representing the physical processes that create them? Once the physics and mathematical formulation are described, what are the techniques for transforming them into computer programs? The authors deal with all these aspects and take a "how to" approach in guiding the reader through the development of computer models for simulating sediment transport in coastal environments. In addition to describing the devised computer programs, the book provides a basis for those wishing to formulate their own mathematical models for simulating nearshore processes.

Book Description
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)

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated 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 ac tivity 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 concerned if the printing and distribution of the volume were handled by an international 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 Corporation 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 25 (thesis year 1980) a total of 10,308 theses titles from 27 Canadian and 214 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 25 reports theses submitted in 1980, on occasion, certain universities do report theses submitted in previous years but not reported at the time.

Book Description
This book represents the efforts of over a hundred individuals who planned and executed the NSTS field experiments, analyzed the billions of data points, and distilled their findings and insights into the summaries found here. Because these experiments were of a scope that will seldom, if ever, be duplicated, and because the program brought together many of the foremost field experimentalists in this country, we all felt from the beginning that it was important to preserve the outcome. This was done in two ways. First, the raw data were made available to any interested investigator within 18 months of the completion of each experiment. Secondly, both the methodology of the experiments and the findings from them were codified in the form of a monograph. This book is that result. I have had the occasion recently (Sediments '87 Proceedings, Vol. 1, pp. 642-651) to assess the NSTS performance. I found that we made giant strides in our understanding of the surf zone hydrodynamics --far more than our fondest expectations at the beginning. We were able to do less than we had hoped about the response of the sediment, largely because of a limited ability to measure it at a point. As I reported in the Sediments '87 assessment, we established a new state of the art in measurement techniques and we demonstrated the effectiveness of large, multi-investigator, instrument-intensive experiments for studying nearshore processes.

Book Description
This book places research into worldwide beach environments in its geomorphological context. Having introduced the systems approach to environmental modelling, and identified the groups of processes operating on beaches, the text is structured in five parts: the first three sections provide a sequential account of the effects of these processes on the beach system; part four focuses on theory relevant to landform stability, then reviews existing empirical, analytical and numerical models; and the final section introduces a computer model and shows its application to the process functions developed earlier.
