Available in PDF, EPUB and Kindle. Book excerpt: This report represents a review and conclusion of several studies conducted at the University of Delaware with the aim of providing numerical model for calculating nearshore wave-induces currents and mean water level fluctuations. The purpose of constructing a numerical model rests on the need to extend our predictive capabilities into situations which lie beyond the scope of analytic methods. In the end, all numerical models, as well as analytical formulations, are limited in scope by the simplifying assumptions incorporated in their theoretical framework; in this regard, the present models represent an attempt to extend present analytic treatments to the case of a complex topography in two dimensions. The models do not consider the associated sediment transport problem, although this capability can be added. Also, the models require that the incident wave field be regarded as monochromatic, or, after some model modifications, narrow banded enough to be represented as a modulated wave train at a single carrier frequency.

Available in PDF, EPUB and Kindle. Book excerpt: In this chapter the theoretical framework for the development of time averaged governing equations for the problem of waves and currents in the nearshore zone is outlined. The development of the numerical circulation models in either the 'linear' or 'nonlinear' form is then described in Chapter III based on the theoretical framework. In general, the development of each model has been described in previous technical reports; the linear model in Birkemeier and Dalrymple (1976), and the nonlinear model in Ebersole and Dalrymple (1979). For this reason, some of the derivations and intermediate steps needed to develop the governing equations are not described in detail in the present report. The reader can refer to the previous work for missing details. However, both models now include the option of calculating wave energy decay due to interaction with the bottom, which has not been included in previous reports. The theory and implementation of this option is described in detail. (Author).

Download or read book An Evaluation of Two Cross-shore Numerical Models in Predicting Subaerial Beach Morphology written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical modeling in the nearshore region has become an important tool in both planning and design for coastal engineers. In recent decades, the complexity of these models has increased as our knowledge of existing processes has matured. However, gaps still remain between what we as engineers understand about the nearshore environment and what actually exists. Due to these uncertainties, modelers have taken different approaches to simulate sediment transport. The objective of this thesis is to evaluate the ability of two cross-shore numerical models, SBEACH and COSMOS, in their ability to predict subaerial beach profile change resulting from storm events. The predicted profiles from each model were compared to actual measured post-storm profiles. Quantitative comparison of results from both models was preformed using BMAP (Beach Morphology Analysis Package). A rating of good, fair, or poor was assigned to the models based on how closely each predicted the measured subaerial profile change. The waterline recession was also analyzed and a rating of reasonable or unreasonable was assigned to each model based on its predicted value. The fundamental difference between the two models is in regards to sediment transport. The SBEACH model predicts sediment transport rates as a function of wave energy dissipation. The COSMOS model utilizes the energetics approach where sediment transport is dependent on mean velocity currents in both the bed and the suspended boundary layers. The results presented within this report show that SBEACH performed equally as well or better in each case. The COSMOS model consistently over predicted erosion on the beach face and recession of the waterline. For the study sites where data was collected for this research, SBEACH is the recommended model by the author.
Book Synopsis Advances in Coastal Modeling by : V.C. Lakhan
Download or read book Advances in Coastal Modeling written by V.C. Lakhan and published by Elsevier. This book was released on 2003-10-24 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book unifies and enhances the accessibility of contemporary scholarly research on advances in coastal modeling. A comprehensive spectrum of innovative models addresses the wide diversity and multifaceted aspects of coastal research on the complex natural processes, dynamics, interactions and responses of the coastal supersystem and its associated subsystems. The twenty-one chapters, contributed by internationally recognized coastal experts from fourteen countries, provide invaluable insights on the recent advances and present state-of-the-art knowledge on coastal models which are essential for not only illuminating the governing coastal process and various characteristics, but also for understanding and predicting the dynamics at work in the coastal system. One of the unique strengths of the book is the impressive and encompassing presentation of current functional and operational coastal models for all those concerned with and interested in the modeling of seas, oceans and coasts. In addition to chapters modeling the dynamic natural processes of waves, currents, circulatory flows and sediment transport there are also chapters that focus on the modeling of beaches, shorelines, tidal basins and shore platforms. The substantial scope of the book is further strengthened with chapters concentrating on the effects of coastal structures on nearshore flows, coastal water quality, coastal pollution, coastal ecological modeling, statistical data modeling, and coupling of coastal models with geographical information systems.

Book Synopsis Mechanics of Coastal Sediment Transport by : J?rgen Freds?e
Download or read book Mechanics of Coastal Sediment Transport written by J?rgen Freds?e and published by World Scientific. This book was released on 1992 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the subject of sediment transport in the marine environment, covering transport of non-cohesive sediment by waves and current in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required. It is intended for M.Sc. and Ph.D. students. The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. It does not present a large number of different formulae for the sediment transport rates under various conditions. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described; in the second, sediment transport and morphological development are treated. The hydrodynamic part contains a review of elementary theory for water waves, chapters on the turbulent wave boundary layer and the turbulent interaction between waves and currents, and finally, surf zone hydrodynamics and wave driven currents. The part on sediment transport introduces the basic concepts (critical bed shear stress, bed load, suspended load and sheet layer, near-bed concentration, effect of sloping bed); it treats suspended sediment in waves and current and in the surf zone, and current and wave-generated bed forms. Finally, the modelling of cross-shore and long-shore sediment transport is described together with the development, of coastal profiles and coastlines.
