Multiscale Physical Processes of Fine Sediment in an Estuary by Yuanyang Wan Pdf

Estuaries are natural highly dynamic and rapidly changing systems, comprising a complex combination of physical processes on many different time- and space- scales. The research conducted a systematic study on the topic of fine sediment physical processes in a meso-tidal convergent alluvial estuary. By means of multi-approaches (field survey, laboratory experiment and numerical modeling) and from multi-angles (data-driven analysis and process-based modeling) we highlight that multiscale (including micro- and macro- scale) physical processes jointly characterize the current and sediment regime in a fine sediment estuarine system. The study presented in this book investigates micro- and macro- scale physical processes of a large-scale fine sediment estuarine system with a moderate tidal range as well as a highly seasonal-varying freshwater inflow. Based on a series of measured, experimented and modelled data, the research highlights that (i) along-channel fresh-salt gradient near an estuarine turbidity maximum zone is a key parameter controlling local density stratification and sedimentation in the channel; (ii) the salinity-induced baroclinic pressure gradient forces are a major factor impacting internal velocity and suspended sediment concentration (SSC) structures; (iii) vertical profiles of current, salinity and SSC within a river plume are dependent on a correct prediction of the development of turbulence; (iv) both suspended particulate matter availability and local residual flow regime are of critical importance for trapping probability of sediment and the occurrence of fluid mud; (v) river discharge impacts the horizontal and vertical distribution of residual current; (vi) seasonally varying wind effect alters the residual currents near the riverine limit; (vii) seasonally varied mean sea level and wind climate jointly shape the saltwater intrusion length near the estuarine front.

Estuaries by Keith R. Dyer Pdf

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.

Estuarine Cohesive Sediment Dynamics by Ashish J. Mehta Pdf

The background for the Workshop on Cohesive Sediment Dynamics - . !!!!!. Special Reference to Physical Processes in Estuaries is briefly outlined in Chapter I. Here I wish to acknowledge those whose support I consider to be pivotal to this under taking. My deepest appreciation goes to Cynthia Vey, whose organizational skills and dedicated effort made the completion of this volume possible. Thanks are also due to Gail Terry for workshop organization, Jean Branson for word processing and Lillean Pieter for helping with drawings. Finally, I must express my sincere appreciation to Arthur Ezra 9f the National Science Foundation for providing support (through Grant No. CEE-8401185) for the workshop, and to Hsiang Wang for depart mental encouragement. With deepest regret, I must note the untimely death of Ranjan Ariathurai, 39, on June 5, 1985, before this volume could be published. He was a guiding force to many within the small group of researchers in cohesive sediment dynamics, and his professional brilliance and inspirational personal qualities constituted the true spirit . behind the workshop. I trust this volume will serve, albeit in a small way, as a fitting memory to this spirit, and to the remarkable professional contributions Ranjan made during his short career. Professor Ray B.

Estuarine Processes by Martin Wiley Pdf

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.

Transfer Processes in Cohesive Sediment Systems by W. R. Parker,D. J. J. Kinsman Pdf

In the transfer of chemical species through the aquatic environment the association with fine sediment particles is often of crucial importance. The n~ture, permanence and kinetics of this association is, in many cases, unknown yet it is central to any effort concerned with predicting the pathways of pollutant transfer and the fluxes along them. It is often unclear to precisely what surface, if any, a pollutant is attached. The transfer of species between surfaces and solution may be chemically or biochemically controlled. These processes may take place within a host framework which has a time and space dependent structure. The natural straining of this framework resulting from physical and chemical processes moves porewater and the dissolved species in it. Thus, to adequately predict the natural transfer of species within a cohesive sediment system the physical, biochemical and chemical processes must be dynamically coupled. This informal colloquium examined topics relevant to the associ ation of pollutant and sediment. These included the mineral particle surfaces and the surrounding ionic associations, methods of describing the particles and the physical, chemical, biochemical and biological processes operating in association with fine sediment substrates. The physical processes of sediment transport were deliberately excluded.

The Estuary as a Filter by Victor S Kennedy Pdf

The Estuary as a Filter contains the proceedings of the Estuarine Research Federation’s seventh biennial conference at Virginia Beach, Virginia, in late October, 1983. In five invited sessions, scientists and managers considered the physical, geological, chemical-geochemical, and biological processes involved in the ""filtering"" role of estuaries and reflected on management implications of these matters. Most of their presentations and reflections are included in this book in order to demonstrate what is known and what needs to be explored further. The papers in this volume are grouped as they were presented at the conference. Thus, physical oceanographers begin the work by considering turbulence, mixing, and circulation processes in estuaries. Geologists then examine estuarine sedimentation, including the roles of flocculation and bioturbation in accelerating this process. Chemists and geochemists describe the interactions among and effects of inputs of nutrients, metals, and organic matter into estuaries, and the fate of radionuclides in these systems. Biological and biochemical processes involving surface foam, microbes, sea grasses, and wetlands are considered, along with carefully derived nutrient budgets of selected estuarine regions. Finally, some of the problems facing managers of estuarine ecosystems in three areas of the United States are described, along with the success story of the ongoing rehabilitation of the Thames Estuary in England.

Hydrodynamics of Estuaries by B. Kjerfve Pdf

These books are divided into two volumes. The first focuses on estuarine physics and physical processes and interpretations. I have, for the most parts, intentionally downplayed engineering applications to estuaries. It is my bias that a deeper understanding is accomplished with a physical approach, whereas an engineering approach is largely geared toward finding a solution to a problem. Of course, it is not always easy to make this distinction. The second volume is a presentation of physical case studies of several important estuaries, spanning the major geomorphic types. I believe that it can be very useful to all areas of the world. I have consciously strived to be more international to scope in selection of both authors and estuarine case studies.
