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.

This book provides an introduction to the complex system functions, variability and human interference in ecosystem between the continent and the ocean. It focuses on circulation, transport and mixing of estuarine and coastal water masses, which is ultimately related to an understanding of the hydrographic and hydrodynamic characteristics (salinity, temperature, density and circulation), mixing processes (advection and diffusion), transport timescales such as the residence time and the exposure time. In the area of physical oceanography, experiments using these water bodies as a natural laboratory and interpreting their circulation and mixing processes using theoretical and semi-theoretical knowledge are of fundamental importance. Small-scale physical models may also be used together with analytical and numerical models. The book highlights the fact that research and theory are interactive, and the results provide the fundamentals for the development of the estuarine research.

In Physical Processes in Estuaries the present day knowledge of the physics of transport phenomena in estuaries and their mathematical treatment is summarized: It is divided into following parts: - Water movements in estuaries - Estuarine fronts and river plumes - Internal waves and interface stability - Fine sediment transport, aggregation of particles, settling velocity of mud flocs - Sedimentation and erosion of fine sediments. For each topic an up-to-date review and recommendations for future research are given, followed by results of original studies. Since estuarine environments are the first to be threatened by urbanization and industrial exploitation this book is an important tool for students and researchers of environmental problems as well as for consultants and water authorities.

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 a unique environment influenced by tidal movements of the sea and freshwater flow of the river. This study addresses a number of knowledge gaps in multi-channel estuaries by developing a predictive analytical approach for salinity intrusion and discharge estimate in multi-channel estuaries. The new approach agrees well with 1-D hydrodynamic models and observations, indicating its applicability in practice. Most importantly, the study 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.

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

Estuarine Processes, Volume II: Circulation, Sediments, and Transfer of Material in the Estuary provides information pertinent to estuarine processes and focuses on dynamic interactions at several levels of organization. This book describes the effects of physical alterations on estuarial hydraulics, dissolved and particulate material support, and on aquatic biota. Organized into six parts encompassing 27 chapters, this volume begins with an overview of the historic changes in salinity balance in the estuarial zone of the Sacramento-San Joaquin Delta. This text then reviews the effect of enlargement of artificial waterway of the Chesapeake and Delaware Canal, which has resulted in substantial alterations of the physical hydrography, biotic populations and chemical environment of the canal and its approaches. Other chapters consider the elements in a mathematical model for estuarial sediment transport. This book discusses as well sediment transport rates in coastal waters. The final chapter deals with accurate estimates of fish abundance for models of many estuarine processes. This book is a valuable resource for ecologists, environmentalists, and scientists.

Pollution of estuaries and coastal marine waters is of profound ecological and societal importance. These coastal environments serve as critical habitat for a multitude of organisms and are of great commercial and recreational value to humans. Designed to meet the research, monitoring, and assessment needs of scientists, administrators, planners, and managers, Pollution Impacts on Marine Biotic Communities is a uniquely comprehensive reference covering pollution in coastal marine and estuarine waters. The book provides a detailed look at the short- and long-term impacts of pollutants on these ecologically important regions. Case studies that reflect a broad range of pollution problems are analyzed, outlining the real-life issues and providing solutions to common problems. Despite being highly sensitive systems, estuarine and coastal marine environments have served as repositories for dredge spoils, sewage sludge, and industrial and municipal effluents for many decades. The adverse effects of these pollutants are only now being fully realized and understood. Pollution Impacts on Marine Biotic Communities includes a basic introduction to the subject of pollution in estuarine and marine environments and also a detailed examination of specific marine pollutants. Both the coverage and the format - which includes abundant illustrations and tables - make this book a valuable reference for scientists, administrators, and students engaged in coastal research and planning.

Accessible to advanced undergraduate students, Physical Oceanography: A Mathematical Introduction with MATLAB® demonstrates how to use the basic tenets of multivariate calculus to derive the governing equations of fluid dynamics in a rotating frame. It also explains how to use linear algebra and partial differential equations (PDEs) to solve basic initial-boundary value problems that have become the hallmark of physical oceanography. The book makes the most of MATLAB’s matrix algebraic functions, differential equation solvers, and visualization capabilities. Focusing on the interplay between applied mathematics and geophysical fluid dynamics, the text presents fundamental analytical and computational tools necessary for modeling ocean currents. In physical oceanography, the fluid flows of interest occur on a planet that rotates; this rotation can balance the forces acting on the fluid particles in such a delicate fashion to produce exquisite phenomena, such as the Gulf Stream, the Jet Stream, and internal waves. It is precisely because of the role that rotation plays in oceanography that the field is fundamentally different from the rectilinear fluid flows typically observed and measured in laboratories. Much of this text discusses how the existence of the Gulf Stream can be explained by the proper balance among the Coriolis force, wind stress, and molecular frictional forces. Through the use of MATLAB, the author takes a fresh look at advanced topics and fundamental problems that define physical oceanography today. The projects in each chapter incorporate a significant component of MATLAB programming. These projects can be used as capstone projects or honors theses for students inclined to pursue a special project in applied mathematics.
