Coastal and Estuarine Processes


Book Description

This book is an introductory treatment to coastal and estuarine processes for earth scientists or engineers. Suitable for a first course on the subject, it covers water waves, surf zone hydrodynamics, tides in oceans and estuaries, storm surges, estuarine mixing, basic sediment transport, coastal morphodynamics and coastal groundwater dynamics. The book contains a substantial amount of new material. For example, the explicit, analytical treatment of transient, forced long waves strongly enhances the discussion on tsunami, storm surges and surf beat. The treatment of turbulent mixing includes finite mixing length effects, which provide an explanation for differential diffusion of different sediment sizes in suspension. The recently discovered effects of acceleration skewness and boundary layer streaming are also included in the basic sediment transport models. In addition, the treatment of beach groundwater dynamics: The mechanisms by which waves as well as tides drive groundwater motion, builds the link between the previously unconnected fields of coastal hydraulics and regional groundwater modeling. To serve as an effective reference book for professionals, the book is fully indexed and comprehensively cross referenced.




Estuarine Ecology


Book Description

This textbook covers the physical and chemical aspects of estuaries, the biology and ecology of key organisms, the flow of organic matter through estuaries, and human interactions, such as the environmental impact of fisheries on estuaries and the effects of global climate change on these important ecosystems. Each chapter will begin with basic concepts and then move on to describing applications and current practice. This new edition is being authored by a team of world experts from the estuarine science community.







Estuarine and Wetland Processes


Book Description

Estuaries and Wetlands are important coastal resources which are subject to a great deal of environmental stress. Dredging, construction, creation of intertidal wetlands, regulation of fresh water flow, and pollution are just a few of the activities which affect these coastal systems. The need to predict the effects of these perturbations upon ecosystem dynamics, particularly estuarine fisheries, as well as on physical effects, such as sedimentation and salt intrusion, is of paramount importance. Prediction requires the use of models, but no model is likely to be satisfactory unless fundamental physical, chemical, sedimentological, and biological processes are quantitatively understood, and the appropriate time and space scales known. With these considerations in mind, the Environmental Laboratory, U. S. Army Engineer Haterways Experiment Station,* Vicksburg, Mississippi, sponsored a workshop on "Estuarine and Wetland Processes and Water Quality Modeling" held in New Orleans, June 1979. The contents of this volume have been selected from the workshop papers. The resulting book, perhaps more than any other symposium proceed ings on estuaries and wetlands, attempts to review important pro cesses and place them in a modeling context. There is also a distinct applied tinge to a number of the contributions since some of the research studies were motivated by environmental assessments. The difference in title between this volume and the workshop re flects more accurately the contents of the published papers.




Contemporary Issues in Estuarine Physics


Book Description

Estuaries are of high socioeconomic importance with twenty-two of the thirty-two largest cities in the world located on river estuaries. Estuaries bring together fluxes of fresh and saline water, as well as fluvial and marine sediments, and contain high biological diversity. Increasingly sophisticated field observation technology and numerical modeling have produced significant advances in our understanding of the physical properties of estuaries over the last decade. This book introduces a classification for estuaries before presenting the basic physics and hydrodynamics of estuarine circulation and the various factors that modify it in time and space. It then covers special topics at the forefront of research such as turbulence, fronts in estuaries and continental shelves, low inflow estuaries, and implications of estuarine transport for water quality. Written by leading authorities on estuarine and lagoon hydrodynamics, this volume provides a concise foundation for academic researchers, advanced students and coastal resource managers.




Ecology of Estuaries


Book Description

The principle objective of this book is to review the biological characteristics of estuaries. The volume has been as a text for undergraduates and graduate students as well as reference for scientists conducting research on estuarine systems. And the rapid development of estuarine ecology as a field of scientific inquiry reflects a growing awareness of the immense societal importance of a coastal ecosystem. While the volume of literature on estuaries amassed, scientists deemed it necessary to synthesize the field periodically. Consiquently, several books have been produced in recent years which examine variuous aspects of the disicpline.







Estuarine Ecohydrology


Book Description

Estuarine Ecohydrology, Second Edition, provides an ecohydrology viewpoint of an estuary as an ecosystem by focusing on its principal components, the river, the estuarine waters, the sediment, the nutrients, the wetlands, the oceanic influence, and the aquatic food web, as well as models of the health of an estuary ecosystem. Estuaries, the intersection of freshwater and coastal ecosystems, exhibit complex physical and biological processes which must be understood in order to sustain and restore them when necessary. This book demonstrates how, based on an understanding of the processes controlling estuarine ecosystem health, one can quantify its ability to cope with human stresses. The theories, models, and real-world solutions presented serve as a toolkit for designing a management plan for the ecologically sustainable development of estuaries. - Provides a sound knowledge of the physical functioning of an estuary, a critical component of understanding its ecological functioning - Ideal reference for those interested in marine biology, oceanography, coastal management, and sustainable development - Describes the essentials behind conceptual and numerical models of the health of an estuary ecosystem and how to use these models to quantify both human impacts and the value of remediation and management measures - Chapters are written in an accessible way that encourages collaboration between aquatic, marine, and wetland biologists, ecologists, oceanographers, geologists, geomorphologists, chemists, and ecosystem modelers - Covers the physical, chemical, and biological elements of estuary environments, indicating that the essence of an estuary's functioning lies in its connectivity with the adjacent catchment and the marine/coastal system




Estuarine Processes


Book Description

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.
