Book Description
Nineteen papers representing the results of a project funded by the Commission of the European Communities to study macrotidal estuaries from the Elbe to the Tagus in a comparative and coherent manner by way of a standardized methodology. The papers address topics in primary production, bacterial processes, zooplankton, hyperbenthos, meiobenthos, macrobenthos, and modeling. A major result of the comparison is that salinity gradients explain species succession within each estuary, yet similar succession series are found at different salinity levels in different estuaries. The volume is reprinted from Hydrobiologia, v.311, 1995. Includes graphs and maps. Lacks an index. Annotation copyright by Book News, Inc., Portland, OR

Book Description
"This book is a valuable theoretical resource for graduate students specialising in estuary processes and for researchers in related disciplines. It is also a useful guide for practitioners and consultants with its wide range of analytical equations, describing hydraulic, mixing and salt intrusion processes in estuaries."--Jacket.

Book Description
The book describes an integrated theory that links estuary shape to tidal hydraulics, tidal mixing and salt intrusion. The shape of an alluvial estuary is characterised by exponentially varying width and the absence of bottom slope. This topography is closely related to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal excursion, phase lag, tidal damping, tidal amplification), wave celerity, lateral and vertical mixing and salt intrusion. The book presents a review of the state of the art, a comprehensive theoretical background and ample case illustrations from all over the world. It provides tools with which human interference in estuary dynamics can be described and predicted, resulting from, for instance: upstream fresh water abstraction, dredging, climate change or sea-level rise. In describing the interactions between tide, topography, water quality and river discharge, it provides useful information for hydraulic engineers, morphologists, ecologists and people concerned with water quality in alluvial estuaries.Although the book can be used as a text book, it is mainly a monograph aimed at graduate students and researchers.* Provides new integrated theory for tidal hydraulics, tidal mixing and salt intrusion in alluvial estuaries* Presents a consistent set of analytical equations to compute tidal movement, tidal mixing and salt intrusion, derived from the fundamental laws of conservation of mass and momentum* Serves as a practical guide with many illustrations of applications in real estuaries

Book Description
This volume focuses on the nutrient and organic matter inputs in estuaries and other coastal ecosystems, their effects on geochemistry and community structure and possibilities for recovery of the systems to a trophic state that is beneficial for man and nature. The book provides many examples of the effects of the enhanced supply of nutrients and organic matter on the chemical features of the water and on the structure, metabolism and trophic pathways of the biological communities. Also included are several case studies providing considerable insight into the response of the different coastal ecosystems to long term changes in the trophic state of the water. Current knowledge on modeling as a tool to manage the trophic state of the coastal ecosystems is also dealt with, making this book one of interests to scientist and students as well as managers.

Book Description
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

Book Description
Multi-channel estuaries, such as the Mekong Delta in Vietnam and the Scheldt in the Netherlands, have characteristics of both the river and the sea, forming an environment influenced by tidal movements of the sea and freshwater flow of the river. This study discusses a predictive analytical approach for salinity intrusion and discharge estimate in multi-channel estuaries. The new approach agrees with 1-D hydrodynamic models and observations, indicating its applicability in practice. It has successfully developed a new theory and a new equation to quantify tidal pumping due to ebb-flood channel residual circulation and the related salt dispersion.
