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

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

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.

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.

This landmark publication collates information and studies on the use of estuaries, and specific habitats within them, as nursery, feeding and refuge areas, and migration routes of marine and other fish, many of which are of commercial and conservation importance. The editors and authors of the book have carefully compiled a huge wealth of information from the work of 18 organizations across 11 countries, providing a unique collection of data never before brought together within the covers of one book. Chapters within this exceptional publication cover habitat use by fishes, recruitment and production in estuaries, links between fish and other trophic levels, endangered and rare species, estuarine development and restoration, environmental quality of estuaries and the management of estuarine fishes. The book notably contains extensive chapters on field methods and data analysis. Fishes in Estuaries is an essential tool and reference source for fisheries and environmental managers, fish biologists, environmental scientists, aquatic ecologists and conservation biologists. Libraries in all universities and research establishments where biological sciences are studied and taught should have copies of this book on their shelves, as should personnel employed in regulatory and consultant capacities, such as within rivers authorities, environment agencies and fish and wildlife departments. Comprehensive coverage of commercially exploited species. Internationally known and respected contributors. Multi-contributor approach providing very detailed coverage. Estuaries are a vitally important ecosystem.

The main objective of this research is to investigate the governing processes and characteristics that drive morphodynamic evolution in alluvial estuaries by application of a process-based numerical model (Delft3D). It is of utmost importance to understand estuarine processes so that impact of human interference (like dredging and land reclamation)
