The ability to predict the movement of cohesive sediment within coastal, estuarine or inland waters has a significant economic and ecological importance in the development of new engineering works and the maintenance of existing installations. Dynamics of estuarine muds clearly describes the most up-to-date developments in this field and contains information about improved procedures and how they can be applied to a variety of engineering projects. Drawing on a wide range of new data and new concepts in mud research, this concise volume presents the main processes of cohesive sediment behaviour, namely, erosion, transport, deposition and consolidation. It includes subsections on Knowledge, intended to show the practising engineer which parameters are important in each of the processes and Procedure, which will enable broad estimates of erosion, transport, deposition and consolidation to be made based on knowledge of the site conditions. Dynamics of estuarine muds is essential reading for the practising engineer who is involved in coastal, estuarine or inland water construction. A companion volume to Dynamics of marine sands, this excellent book provides invaluable information about this complex topic in a readily accessible manner.

The background for the Workshop on Cohesive Sediment Dynamics - . !!!!!. Special Reference to Physical Processes in Estuaries is briefly outlined in Chapter I. Here I wish to acknowledge those whose support I consider to be pivotal to this under taking. My deepest appreciation goes to Cynthia Vey, whose organizational skills and dedicated effort made the completion of this volume possible. Thanks are also due to Gail Terry for workshop organization, Jean Branson for word processing and Lillean Pieter for helping with drawings. Finally, I must express my sincere appreciation to Arthur Ezra 9f the National Science Foundation for providing support (through Grant No. CEE-8401185) for the workshop, and to Hsiang Wang for depart mental encouragement. With deepest regret, I must note the untimely death of Ranjan Ariathurai, 39, on June 5, 1985, before this volume could be published. He was a guiding force to many within the small group of researchers in cohesive sediment dynamics, and his professional brilliance and inspirational personal qualities constituted the true spirit . behind the workshop. I trust this volume will serve, albeit in a small way, as a fitting memory to this spirit, and to the remarkable professional contributions Ranjan made during his short career. Professor Ray B.

This volume is the product of the International Conference on Cohesive Sediment Transport (INTERCOH 2003) held at the Virginia Institute of Marine Science, U.S.A., during October 1-4, 2003. The topics included in this monograph range from basic research on cohesive sediment dynamics to practical applications. Also included with this book is a database that contains all experimental results as well as a comparison of numerical simulation results supported by the COSINUS project. * Provides fundamental knowledge of the dynamics of cohesive sediments * Presents practical applications of new finds on sedimentary processes * Includes valuable ready-for-use data

Covers the movement of mud, sand, and gravel on the continental shelf in the nearshore zone, on beaches, and in estuaries. A multi-disciplinary treatment integrating marine geology, oceanography, and engineering. Presents concepts in engineering sediment distribution patterns that improve the prediction of erosion and deposition rates. Reviews background material as well as the results of recent research.

The practical engineer looking for an urgent solution to a sediment-related project often finds that the results of the relevant academic research are published in unfamiliar language in publications that are not easily available. Dynamics of marine sands bridges the gap between academic research and practical applications by summarising the research results in a unified form, backed up with worked examples and case studies. This comprehensive new book presents methods for calculating the various hydrodynamic and sediment dynamic quantities necessary for marine sediment transport applications, and recommends the most appropriate methods to use for engineering projects.

Estuarine Ecohydrology focuses on the principal components of an estuary. The book demonstrates how one can quantify an estuarine ecosystem's ability to cope with human stresses. The theories, models, and real-world solutions covered will serve as a toolkit for designing a management plan for the ecologically sustainable development of an estuary. This book is organized into seven chapters dealing with topics such as estuarine water circulation; estuarine sediment dynamics; tidal wetlands; estuarine food webs; and ecohydrology models and solutions. Although each chapter contains rigorous specialist knowledge, it is presented in an accessible way that encourages multi-disciplinary collaboration between such fields as hydrology, ecology and mathematical modeling. Estuarine Ecohydrology is appropriate for use as a textbook and as a reference for researchers; advanced undergraduate and graduate students in marine biology, oceanography, coastal management, and coastal engineering; coastal developers; resources managers, shipping operators; and those involved in estuarine fisheries and sustainable development communities. * Appropriate for use as a textbook and as a reference * Focuses on the principal components of an estuary * Presents theories, models, and real-world solutions to serve as a toolkit for designing a management plan for the ecologically sustainable development of an estuary
