Available in PDF, EPUB and Kindle. Book excerpt: Dispersion in Estuaries and Coastal Waters describes the physical processes which result in the dilution of a substance in the marine environment. The emphasis is mainly on the fundamental mechanisms of dispersion and the occurrence of these processes in estuaries and coastal waters Aspects of the present understanding of fluid dynamics in homogenous and stratified flows are discussed, with particular reference to the relevance of flow conditions to the turbulent state. The book describes how the associated dispersion processes are represented in mathematical models to quantify dilution in marine systems and the experimental techniques used to derive the mixing parameters required for the models. Concluding by discussing the application of the concepts of dispersion in well mixed, stratified and partially mixed systems, Dispersion in Estuaries and Coastal Waters acts as an excellent guide book for those needing to solve practical problems relating to marine dispersion. It also provides a useful review of dispersion as it cites key publications, both recent and long-standing, which are invaluable in interpreting and quantifying the dilution and fate of material in the marine environment.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 50. Continental shelves, coastal seas and estuaries contain many valuable resources for economic, social, tourist and recreational activity. The majority of the world's largest cities are located on the coastline. For example, 86% of the total Australian population is located in the coastal zone. Almost 75% of the global harvest of fisheries comes from coastal areas. However, it is also the region into which anthropogenic wastes are discharged, leading to degradation of the environment. As we become more aware of the consequences of these discharges, and develop new management strategies to avoid detrimental effects in estuaries and coastal regions, it is clear that an understanding of mixing processes plays a very important role in dispersion of introduced contaminants. This volume consists of 30 papers, each dealing with different aspects of mixing processes in the marine environment. The following topics are covered: inner continental shelf processes, shelf?]estuary interactions, estuarine processes, sediment transport processes, ocean outfalls, and theoretical studies. The majority of the papers include results of field experiments with some degree of integration with numerical and/or analytical models. A wide variety of environments from different countries are presented. These include micro?] and macro?]tidal environments, areas influenced by major oceanic current systems, enclosed and semi?]enclosed embayments, and mangrove environments.

This book was released on 2013-11-11 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Estuarine and Wetland Processes written by Keith B. Ater and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Dispersion and Tidal Dynamics of Channel Shoal Estuaries written by Christopher Dean Holleman and published by . This book was released on 2013 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries, and the varied ecosystems they support, are affected by human action in many ways. One of the fundamental environmental questions pertaining to estuaries is how material is mixed into ambient waters and transported within and beyond the estuary. Characterizing transport and mixing is essential for tackling local environmental questions, such as gauging the water-quality impacts of a wastewater outfall, or how dredging may alter estuarine circulation. In many estuaries the dominant physical dispersion mechanism is shear dispersion. A fundamental and idealized approach to the scalar transport problem is undertaken, in which canonical shear dispersion regimes are augmented with a new, intermediate regime. This mode of shear dispersion, in which the longitudinal variance of the plume increase with the square of time, is likely to occur in channel-shoal basins where bathymetric transitions can create sheared velocity profiles. A key tool in the engineer's arsenal for pursuing studies of scalar transport is the numerical model, but care must be taken to separate physical mixing effects from numerical artifacts. Unstructured models are particularly well-suited to estuarine problems as the grid can be adapted to complex local topography, but the numerical errors of these models can be difficult to characterize with standard methods. An in-depth error analysis reveals a strong dependence of numerical diffusion on the orientation of the grid relative to the flow. Flexible grid generation methods allow for optimizing the grid in light of this dependence, and can decrease across-flow numerical diffusion by a factor of two. The most far-reaching impact of our actions, though, must certainly be global climate change. A period of rising sea level is being ushered in by climate change, and the final research-oriented chapter seeks to further our understanding of how rising sea levels will affect basin-scale tidal dynamics. Numerical and analytic approaches show that as basins get deeper tidal amplification becomes more effective and tidal range increases. The crux of the analysis, though, is the inclusion of inundation within these scenarios. Inundated areas dissipate incident tidal energy, countering the added amplification due to basins becoming deeper. The net effect, in the case of San Francisco Bay, is that tidal amplification under sea level rise actually decreases, such that a particular rise in mean higher high water in the coastal ocean is predicted to raise mean higher high water within the bay by a lesser amount.
Download or read book Contemporary Issues in Estuarine Physics written by Arnoldo Valle-Levinson and published by Cambridge University Press. This book was released on 2010-01-28 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Coastal and Estuarine Processes written by Peter Nielsen and published by World Scientific Publishing Company. This book was released on 2009-04-21 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers water waves, surf zone hydrodynamics, tides in oceans and estuaries, storm surges, estuarine mixing, basic sediment transport, coastal morphodynamics and coastal groundwater dynamics. It is an introductory treatment, suitable for a first course in coastal and estuarine processes for earth scientists or engineers. Yet, there are substantial amounts of new material that are included, such as the explicit, analytical treatment of transient, forced long waves. Inclusion of this material will in turn strongly enhance the introductory treatment of tsunami, storm surges and surf beat. The treatment of sine wave theory emphasizes expressions which are explicit in the water depth h (using koh instead of kh) so that they can easily be differentiated or integrated with respect to h. This is a major pedagogical advantage because of the enhanced transparency. The treatment of turbulent mixing includes finite mixing length effects which provide an explanation for differential diffusion of different sediment sizes in suspension. The effects of acceleration skewness and boundary layer streaming are also included in the basic sediment transport models. The inclusion of beach groundwater dynamics — including the mechanisms by which waves as well as tides drive groundwater motion — provides a link between the previously unconnected fields of coastal hydraulics and regional groundwater modeling. Serving as a good reference book, it is fully indexed and comprehensively cross referenced. Abundant references to more detailed texts are also provided.

This book was released on 1993-02-01 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Close to one-half of all Americans live in coastal counties. The resulting flood of wastewater, stormwater, and pollutants discharged into coastal waters is a major concern. This book offers a well-delineated approach to integrated coastal management beginning with wastewater and stormwater control. The committee presents an overview of current management practices and problems. The core of the volume is a detailed model for integrated coastal management, offering basic principles and methods, a direction for moving from general concerns to day-to-day activities, specific steps from goal setting through monitoring performance, and a base of scientific and technical information. Success stories from the Chesapeake and Santa Monica bays are included. The volume discusses potential barriers to integrated coastal management and how they may be overcome and suggests steps for introducing this concept into current programs and legislation. This practical volume will be important to anyone concerned about management of coastal waters: policymakers, resource and municipal managers, environmental professionals, concerned community groups, and researchers, as well as faculty and students in environmental studies.
Download or read book Estuarine Circulation written by Bruce J. Neilson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries exist along the edge of the oceans and seas, and are char acterized by the dilution of sea water by inflowing fresher waters. The motion and interaction of these two types of water (fresh and salt water) determine the salinity distribution within the estuary and that, in turn, affects the organisms residing there. The purpose of this vol ume is to review the status of our understanding of estuarine circu lation and how the circulation patterns affect living and nonliving resources in estuaries. For many years, the primary paradigm for estuarine circulation was the two-layered net or nontidal gravitational circulation pattern first proposed by Dr. Donald Pritchard in his studies of the James River estuary. During the last decade or so, research has focused on the many variations about this theme and the factors that control the transport processes. Many of these aspects are covered in the initial papers in this volume. Water movement, of course, is of interest be cause it transports marine organisms, sediments, and pollutants. Es tuarine circulation has a significant effect on estuarine food chains, and on the distribution and abundance of organisms, such as the American oyster, that are freely transported by the currents during larval stages. The intent is to bring together many of these topics in a single volume. This volume is dedicated to Dr. Donald W.
Download or read book Mixing in Inland and Coastal Waters written by Hugo B. Fischer and published by Elsevier. This book was released on 2013-10-22 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an outgrowth of research contributions and teaching experiences by all the authors in applying modern fluid mechanics to problems of pollutant transport and mixing in the water environment. It should be suitable for use in first year graduate level courses for engineering and science students, although more material is contained than can reasonably be taught in a one-year course, and most instructors will probably wish to cover only selected potions. The book should also be useful as a reference for practicing hydraulic and environmental engineers, as well as anyone involved in engineering studies for disposal of wastes into the environment. The practicing consulting or design engineer will find a thorough explanation of the fundamental processes, as well as many references to the current technical literature, the student should gain a deep enough understanding of basics to be able to read with understanding the future technical literature evolving in this evolving field.
