"This book contains the papers presented at the Second International Conference on Computer Modelling of Seas and Coastal Regions, held in Cancun, Mexico, in September 1995. The conference attracted contributions from many different countries, covering a multitude of topics and techniques in the areas of shallow water models, pollutant transport and dispersion, wave propagation, coastal erosion, littoral drift, tidal simulation, storm surges, estuaries, and coastal lakes and lagoons."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

This book Computer Modelling of Seas and Coastal Regions is the first volume of the two volume proceedings of the International Conference on Computer Modelling of Seas and Coastal Regions and Boundary Elements and Fluid Dynamics, held in Southampton, U.K., in April 1992. The importance of accurate modelling of seas and coastal regions is empha sized by the need for predicting their behaviour under extreme conditions. Problems, such as pollution of these areas, have become a major interna tional concern and the related environmental problems need further study using techniques which can be used to determine the ways in which the water systems respond to different effects and try to minimize the damage. They can also lead to the development of early warning systems in combina tion with remote sensing equipment and experimental sampling techniques. Furthermore, once a disaster occurs, the model can be used to optimize the use of the available resources. The conference addresses coastal region modelling both under normal and extreme conditions, with special reference to practical problems, currently being experienced around the world. Many of the delegates are actively involved in the modelling of seas and coastal regions. This volume includes sections on waves, tides, shallow water circulation and channel flow, siltation and sedimentation, pollution problems, and computu tational techniques. The organizer would like to thank the International Scientific Advisory Committee, the conference delegates and all those who have actively sup ported the meeting.

Aiming to address the subject of computer modelling of seas and coastal regions under normal and extreme conditions, this volume examines the computer modelling of seas and coastal regions.

The importance of accurately modelling seas and coastal regions is emphasized by the need for a better understanding of their normal behaviour and response to extreme conditions. Pollution of these areas has become a major international concern and the related environmental problems need further study to design remedial actions. Computer models are an efficient tool to determine the water systems, in combination with remote sensing equipment and experimental sampling techniques.

In many areas nutrient loadings to aquatic ecosystems have increased considerably as a result of population growth, industrial development and urbanisation. This has resulted in enhanced growth of phytoplankton, shifts in composition of the plankton community and changes in the structure of ecosystems, which are often considered to be objectionable. To help understanding these processes and to predict future conditions, a mathematical model, BLOOM, has been developed and applied since 1977. It simulates the biomass and composition of phytoplankton and macro algae in relation to the amount of nutrients, the under water light climate and grazing.

This volume presents the proceedings of an international conference organised by the Institution of Civil Engineers together with the Institution of Engineering in Ireland. It draws together the practical experiences gained by practising geotechnical engineers on such projects as the resund Tunnel, Hong Kongs Western Harbour Crossing, the Medway Tunnel and the River Lee Tunnel in Cork.All aspects of immersed tube tunnel projects are discussed, from the geotechnical and hydraulic characteristics of tunnel sites, through the planning and design phases to the actual construction of tunnels.

This new Encyclopedia of Coastal Science stands as the latest authoritative source in the field of coastal studies, making it the standard reference work for specialists and the interested lay person. Unique in its interdisciplinary approach. This Encyclopedia features contributions by 245 well-known international specialists in their respective fields and is abundantly illustrated with line-drawings and photographs. Not only does this volume offer an extensive number of entries, it also includes various appendices, an illustrated glossary of coastal morphology and extensive bibliographic listings.

Global warming, melting polar caps, rising sea levels and intensifying wave-current action, factors responsible for the alarming phenomena of coastal erosion on the one hand and adverse environmental impacts and the high cost of 'hard' protection schemes, on the other, have created interest in the detailed examination of the potential and range of applicability of the emerging and promising category of 'soft' shore protection methods. 'Soft' methods such as beach nourishment, submerged breakwaters, artificial reefs, gravity drain systems, floating breakwaters, plantations of hydrophylous shrubs or even dry branches, applied mostly during the past 20 years, are recognised as possessing technical, environmental and financial advantageous properties deserving more attention and further developmental experimentation than has occured hitherto. On the other hand, 'hard' shore protection methods such as seawalls, groins and detached breakwaters, artefacts borrowed from port design and construction technology, no matter how well designed and well implemented they may be, can hardly avoid intensification of the consequential erosive, often devastating, effects on the down-drift shores. Moreover, they often do not constitute environmentally and financially attractive solutions for long stretches of eroding shoreline. Engineers and scientists practising design and implementation of shore defence schemes have been aware for many years of the public demand for improved shore protection technologies. They are encouraging efforts that promise enrichment of those environmentally sound and financially attractive methods that can be safely applied.

Sediment Transport in Aquatic Environments is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes. However, the physical sedimentary processes can vary quite considerably depending upon whether the local sediments are fully cohesive, non-cohesive, or a mixture of both types. For this reason for more than half a century, scientists, engineers, hydrologists and mathematicians have all been continuing to conduct research into the many aspects which influence sediment transport. These issues range from processes such as erosion and deposition to how sediment process observations can be applied in sediment transport modeling frameworks. This book reports the findings from recent research in applied sediment transport which has been conducted in a wide range of aquatic environments. The research was carried out by researchers who specialize in the transport of sediments and related issues. I highly recommend this textbook to both scientists and engineers who deal with sediment transport issues.
