Estuaries is a comprehensive introductory text emphasizing the physical processes involved in the mixing of sea and river water and the transport of fine sediments within the complex estuarine topographic context. The theoretical and mathematical formulation of these processes are treated at a fairly elementary level, and are used to develop a foundation for more extensive study. The second edition retains the classical approaches to the tidally averaged circulation and mixing conditions but broadens them to consider recent advances in the understanding of processes occurring within the tide. The scope has also been widened to include more detail on the morphology of estuaries and their development, the fluxes of suspended fine sediments, and the generation and maintenance of turbidity maximum. The book provides an excellent introduction for research students in oceanography, environmental science, geography, geology, and water and coastal engineering. It will also be useful as a reference book for those working in water quality, morphological modelling and estuarine environmental management.

Jim Green 1.1 THE THAMES ESTUARY:A PERSONAL VIEW For almost 50 years I have lived close to the Thames estuary (Figure 1.1). In the early 1950s, from our flat in Pimlico, we could walk along the embankment opposite Battersea Power Station. At low tide, the exposed mud had large red patches caused by the haemoglobin in innumerable tubificid worms. These formed the basis of a minor trade. Men with waders and sieves would collect the worms and sell them to the aquarium trade as food for fishes.The superabundance of these worms depended on the gross organic pollution of this reach of the Thames. Towards the end of the 1950s we moved to Teddington, within a few minutes' walk from the lock. Casual observation of the birds on the river indicates an increase in the piscivores over the last 20 years.Cormorants tPhalacrocorax carbo) are regularly seen, and grey herons (Ardea cinerea) are more abundant. On a good day it is possible to see up to eight herons around the weir and below the lock. Another bird that is now common­ place in the area is the great-crested grebe (Podiceps cristatus).The regular mallard (Anas platyrhynchos)and Canada geese (Branta canadensis)are some­ times joined by tufted duck (Aythafuligula)and mandarin (Aixgalericulata).

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

Acknowledging the present inability to determine objectively the status and trends among estuarine ecosystems, the environmental research community has recently stepped up efforts to develop and evaluate meaningful estuarine indicators. This goal requires the effort of researchers from a broad spectrum of disciplines. In order to expedite this initiative, many of the world's leading estuarine scientists came together to present their views at the 2003 Estuarine Indicators Workshop. Derived from this conference of leading estuarine scientists, Estuarine Indicators presents the principles, concepts, practical use, and application of indicators in estuarine research and management practices. Topics include: the theory behind environmental indicators and their presumed attributes; the methods and protocols of indicator development and evaluation; a presentation of effective and ineffective indicator examples; and discussions of the future directions in research and management practices. This is an ideal reference for researchers, scientists, and students from any field dealing with estuaries and estuarine ecosystems. Its introductory-level chapters are accessible to novices and seasoned experts alike, and the applications and interpretation of research data suit the needs of environmental managers. This is a truly multidisciplinary, comprehensive compendium upon which future research will undoubtedly be built.

The ongoing growth of human populations within US coastal regions continues to increase habitat loss, eutrophication, organic loading, overfishing, and other anthropogenic stressors in estuarine waters. The National Estuarine Research Reserve System (NERRS) is a federally funded initiative that addresses these critical estuarine problems and coastal resource issues at 25 sites in 21 states. Now estuarine and watershed scientists, resource managers, community planners, and other professionals dealing with coastal zone issues have an expert resource describing the NERRS program, organization, goals, and management strategy. Estuarine Research, Monitoring, and Restoration first defines the components and technical aspects of the NERRS program, then provides valuable insight into the program through the presentation of six case studies of NERRS sites. This book examines estuarine problems including degraded water quality, reduction of biodiversity, and problematic invasive species, then analyzes the human impacts affecting estuaries. The comprehensive analysis of the six estuarine reserve locations characterizes each region's physical, chemical, and biological conditions from the perspective of the NERRS program. These case studies include a cross section of sites from three coasts, each study emphasizing the importance of unified efforts of government and citizens to successfully maintain the ecology of these critical areas.
