Offshore And Coastal Modelling

The papers contained in this volume were presented orally at the seventh POLYMODEL conference, held at Sunderland Polytechnic in the United King dom in May 1984 and sponsored by Barclays Bank PLC and Imperial Chemical Industries Ltd. The conferences are organised annually by the North East of England Polytechnic's Mathematical Modelling and Computer Simulation Group - POLYMODEL. The Group is a non-profit making organisation based on the mathematics department of the three polytechnics in the region and has membership drawn from those educational institutions and from regional industry. Its objective is to promote research and collaboration in mathematical and computer-based modelling. After a short introductory chapter, the volume may be considered as dividing naturally into four parts. Chapters 2 to 5 constitute the first part on Tides, Storm Surges and Coastal Circulations which deals with the hydrodynamics of coastal seas. Chapters 6 to 11 concern Coastal Engine ering Modelling and discuss such coastal phenomena as beach erosion, sediment transport, and non-linear waves. The third part (Chapters 12 to 16) on Offshore Structures considers sea structures in general and the connections between the structures (hoses, moorings, pipelines) in particular. The last two chapters focus on Offshore Corrosion problems.

Modelling is now an accepted part in the understanding, prediction and planning of environmental strategies. Perfect for undergraduate students and non-specialist readers, Modelling Coastal and Marine Processes (2nd Edition) offers an introduction into how coastal and marine models are constructed and used. The mathematics, statistics and numerical techniques used are explained in the first few chapters, making this book accessible to those without a high-level maths background. Later chapters cover modelling sea bed friction, tides, shallow sea dynamics, and ecosystem dynamics. Importantly, there is also a chapter on modelling the impact of climate change on coastal and near shore processes. New to this revised edition is a chapter on tides, tsunamis and the prediction of sea level, and additional material on the new application of the numerical techniques: flux corrected transport, finite volumes and adaptive grids to coastal and marine modelling.

Modeling is a major tool for important environmental strategies. This book helps to understand and criticize the models of the shallow sea and coastal environments. It includes topics that cover the numerical schemes used, the modeling of the sea bed, modeling of shallow sea dynamics, and the modeling of ecosystems and animals.

This book systematizes the concepts of contemporary coastal zone management and suggests possible structural and non-structural management tools for decision-making processes. Some successful adaptation measures and case studies on oceanic processes and coastal protection are discussed. High-frequency communications in coastal and marine environments are also addressed.All chapters contribute relevant information and useful content to scientists and other readers interested or concerned about the lack of adequate management actions and the installation of appropriate protections or their ineffectiveness in containing coastal vulnerabilities and risks.

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.

Coastal engineering is a field which has grown in importance over the last forty years as mankind has utilised and become dependent on the coastlines of the world to a greater extent. The activities in the field include the study of wave dynamics, shoreline erosion and protection, harbor and breakwater design, dredging technology, estuary mechanics and storm surge calculations, as well as offshore structural design. In all of these areas the level of actvity is high and the state of art has imporved dramatically since the 1940's. An important aspect of all these areas of research is the use of model studies. This volume consists of a number of papers which cover various aspects of physical modelling in coastal engineering, including the generation of waves in the laboratory, the modelling of sediment transport and the application to various engineering problems. The intent is to provide the reader with an overview of the research actvities of indviduals who represent major laboratories in their countries: to include Denmark, Scotland, Canada, the People's Republic of China, England, the Netherlands and the U.S.

While the existing literature on offshore structures touch on model testing, a comprehensive text discussing the design, construction, instrumentation, testing and analysis of the physical model is lacking. This book fills that vacuum and provides, through its survey of the theoretical and practical aspects of physical modeling, an in-depth coverage of the technology of model testing. Its usefulness runs through the entire field of engineering, reaching far beyond its focus on offshore construction; and its breadth of scope should appeal not only to engineers and naval architects but to scientists interested in structural or hydraulic testing as well.

The breadth of material in each chapter is truly impressive and valuable; and the abundance of relevant references ... adds considerably to the value of the book. These references will be especially beneficial to those wishing to pursue the individual topics in more detail ... it will serve as a valuable reference to anyone working in this field. It is an important contribution to the field of offshore modelling.” Coastal Engineering
