Download or read book Shore Wave Modulation Due to Infragravity Waves in the Nearshore Zone with Applications written by Saad M. M. Abdelrahman and published by . This book was released on 1986 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The omni-present low frequency wave motion (30-300 sec) contains a substantial fraction of the total wave energy inside the surf zone. A more complete description of nearshore wave processes considers incident short period waves superposed on, and interacting with, long standing waves. The wind waves are modulated in amplitude, wavenumber and direction due to relatively slowly varying depth changes caused by the long waves. The energy in the wind wave band is enhanced by side band growth at the sum and difference frequencies of short and long waves (order 15% at the shoreline). The modulation is identified in the analysis of field data as a positive correlation between the long waves and the wind wave envelope near the shoreline. Considering oblique incident waves, a steady longshore current showing a non-vanishing current at the shoreline is found as a result of the non-linear interaction between monochromatic incident and infragravity waves. An analytical solution describing the unsteadiness of the longshore current is developed. Keywords include: Infragravity, Longshore Current, Sediment transport, and Surf zone dynamics. (Theses).

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the present state of knowledge on infragravity wave motions (nominally 0.003 to 0.05 Hz). Theoretical and observational studies are presented. Most of the studies discussed herein have been published elsewhere, however a few studies discussed in chapter 4 are presented for the first time in this report Measurements of nearshore waves and currents have shown that a significant amount of the total energy can be contained in the infragravity band, and on highly dissipative beaches the infragravity wave variance often dominates over energy in the incident wave band(0.05 to 0.3 Hz). An 8-month data set of infragravity variance measured at 8-m-depth at the shoreline (runup) was compared with incident wave variance. Analysis of the 8-m-depth data showed that high mode edge waves account for about 50 percent of the total infragravity variance, and as high as 80 percent at times. Significant edge wave heights greater than 20 cm were observed at the 8-m depth. Infragravity wave variance was shown to have a higher correlation with swell variance (C = 0.95) than with sea variance (C = 0.61). This report was motivated, in part, by the need to determine the significance of infragravity waves on coastal erosion and structure damage and by the desire to improve coastal engineering solutions to problems associated with nearshore processes.

This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 thougtit 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 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

Download or read book Shore Processes and their Palaeoenvironmental Applications written by Edward J. Anthony and published by Elsevier. This book was released on 2008-11-21 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last five years have been marked by rapid technological and analytical developments in the study of shore processes and in the comprehension of shore deposits and forms, and shoreline change over time. These developments have generated a considerable body of literature in a wide range of professional journals, thus illustrating the cross-disciplinary nature of shore processes and the palaeo-environmental dimension of shore change. The justification of the book lies in bringing together these developments using an objective approach that synthesises current advances, technical progress in the analysis of shores and shore processes, contradictory interpretations, and potential advances using future-generation developments in techniques. The book provides a comprehensive state-of-the-art presentation of shore processes and deposits across ranges of wave energy and tide-range environments, sediment supply and textural conditions, sea-level change, exceptional events and longer-term climate change, based on the most recently published literature in the marine sciences. The book insists on the nested time and spatial scales through which are inter-linked shore processes and deposits, thus providing a better understanding of the way shores change over time. The approach is thus cross-disciplinary, and gap-bridging between processes and deposits, between analytical techniques, and between timescales. The audience is from graduate level upwards, and the book is intended as a comprehensive reference source for professionals in a wide range of coastal science fields (geologists, sedimentologists, geomorphologists, oceanographers, engineers, managers, archaeologists...). * Aimed at graduates and specialists interested in coastal science * Presents background research, recent developments and future trends * Written by a leading scholar and industry expert
Download or read book A Guide to Modeling Coastal Morphology written by Dano Roelvink and published by World Scientific. This book was released on 2012 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Process-based morphodynamic modelling is one of the relatively new tools at the disposal of coastal scientists, engineers and managers. On paper, it offers the possibility to analyse morphological processes and to investigate the effects of various measures one might consider to alleviate some problems. For these to be applied in practice, a model should be relatively straightforward to set up. It should be accurate enough to represent the details of interest, it should run long enough and robustly to see the real effects happen, and the physical processes represented in such a way that the sediment generally goes in the right direction at the right rate. Next, practitioners must be able to judge if the patterns and outcomes of the model are realistic and finally, translate these colour pictures and vector plots to integrated parameters that are relevant to the client or end user. In a nutshell, this book provides an in-depth review of ways to model coastal processes, including many hands-on exercises.
