Book Synopsis Fine Sediment Dynamics in the Marine Environment by : Johan C. Winterwerp
Download or read book Fine Sediment Dynamics in the Marine Environment written by Johan C. Winterwerp and published by Elsevier. This book was released on 2002-06-05 with total page 731 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cohesive sediment, or mud, is encountered in most water bodies throughout the world. Often mud is a valuable resource, synonymous with fertile land, enriching the natural environment and used as an important building material. Yet mud also hinders navigation and consequently, dredging operations have been carried out since ancient times to safeguard navigation. Unfortunately, many mud deposits are now contaminated, endangering the eco-system and increasing the costs of dredging operations. The transport and fate of mud in the environment are still poorly understood and the need for basic research remains. This text contains the proceedings of the INTERCOH-2000 conference on progress in cohesive sediment research. It was the sixth in a series of conferences initially started by Professor Ashish Mehta in 1984 as a "Workshop on Cohesive Sediment Dynamics with Special Reference to the Processes in Estuaries". During these conferences the character of the first workshop has always been maintained, that is, small scale and dedicated to the physical and engineering aspects of cohesive sediments, without parallel sessions, but with ample time for discussions during and after the presentations, and followed by a book of proceedings containing thoroughly reviewed papers. INTERCOH-2000 was integrated with the final workshop of the COSINUS project. This project was carried out as a part of the European MAST-3 programme, and almost all European cohesive sediment workers were involved. INTERCOH-2000 focused on the behaviour and modelling of concentrated benthic suspensions, i.e. high-concentrated near-bed suspensions of cohesive sediment. Special attention was paid to: sediment - turbulence interaction; flocculation and settling velocity; high-concentrated mud suspensions; processes in the bed - consolidation; processes on the bed - erosion; field observations on mud dynamics; instrumentation; and numerical modelling.
Book Synopsis Sediment Transport in Aquatic Environments by : Andrew Manning
Download or read book Sediment Transport in Aquatic Environments written by Andrew Manning and published by BoD – Books on Demand. This book was released on 2011-10-03 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Transport in Aquatic Environments is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes. However, the physical sedimentary processes can vary quite considerably depending upon whether the local sediments are fully cohesive, non-cohesive, or a mixture of both types. For this reason for more than half a century, scientists, engineers, hydrologists and mathematicians have all been continuing to conduct research into the many aspects which influence sediment transport. These issues range from processes such as erosion and deposition to how sediment process observations can be applied in sediment transport modeling frameworks. This book reports the findings from recent research in applied sediment transport which has been conducted in a wide range of aquatic environments. The research was carried out by researchers who specialize in the transport of sediments and related issues. I highly recommend this textbook to both scientists and engineers who deal with sediment transport issues.

Available in PDF, EPUB and Kindle. Book excerpt: "The December 1990 meeting of more than sixty U.S. experts in marine science of the Intra-Americas Sea made 21 recommendations, with deadlines and agencies responsible to carry them out. These recommendations were a consensus of two days of institutional reports, individual conversations, and workshops. The one overwhelming recommendations was to support the UNEP and IOC in the region through active U.S. scientists' participation in problem identification, project planning and execution, and information transfer. A regional emphasis on marine science issues with clearly defined impacts on U.S. interests was considered essential to generating the financial support neccesary to successful project implementation"--Executive summary, paragraph 1
Book Synopsis Applications of Fluorescence Spectroscopy to Environmental Chemistry by : Sarah A. Green
Download or read book Applications of Fluorescence Spectroscopy to Environmental Chemistry written by Sarah A. Green and published by . This book was released on 1992 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in this thesis consists of three parts. The first is a photophysical study of the mechanism of fluorescence quenching by stable nitroxyl radicals, which are becoming an important analytical tool for the study of reactive transients in surface waters (1, 2). In part two, quenching of dissolved organic matter (DOM) fluorescence by nitroxides is employed to investigate the electrostatic propertie~ of DOM in aqueous solution, with the goal of elucidating the apparent ionic strength and pH dependence of metal-fulvic acid binding constants. In part three, the intrinsic optical properties (absorbance, fluorescence, and fluorescence efficiency) of DOM are examined in a coastal region to understand how these properties vary with source. age and sunlight exposure time. Nitroxide-fluorophore adducts were employed to investigate the mechanism by which nitroxyl radicals quench fluorescence (3). Fluorescence quantum yields and lifetimes were measured for a series of adducts, and quenching rates were shown to be quite high (kq~108-1010 s-1), even at distances of ~12 A. Forster or Dexter energy transfer mechanisms are unable to account for the observed rates and lack of solvent dependence in quenching. An excellent correlation is observed between kq and the non-radiative relaxation rate. These results confirm that nitroxyl radicals are very non-selective in their quenching abilities, and suggest that the best analytical probe adducts will include a fluorophore with an appreciable non-radiative relaxation rate. Diffusional quenching by charged and neutral nitroxides was employed to explore the electrostatic properties of fulvic (FA) and humic (HA) acids. Cationic nitroxides were found to be up to 16 times more effective than neutral analogues in quenching the fluorescence of humic materials. This result is attributed to the enhanced coulombic attraction of cations to the anionic FA or HA surface, and is interpreted as an estimate of surface electrostatic potential. Reduction of molecular charge at low pH and shielding of charge at high ionic strength (I) produced diminished enhancements. consistent with this interpretation. The potential was found to be particularly sensitive to ionic strength. suggesting that this electrostatic effect should be of particular importance in transition zones. such as estuaries, where I increases from

Download or read book Estuaries written by Peter J. Wangersky and published by Springer Science & Business Media. This book was released on 2006-01-10 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aspects of the biogeochemistry of estuaries from a variety of environments, from the tropics to the Arctic, are discussed. In most cases the courses of these rivers have been altered by dams or diversions; the results of these changes on the nature of the estuary are also discussed, where such data is available. In the case of the Tasmanian rivers, the estuary of the Huon, a largely untouched river, is contrasted with that of the Derwent, a river heavily influenced by industry. The future state of all of these estuaries may be a sensitive indicator of shifts in global weather patterns.

Book Synopsis Suspended Matter in the Aquatic Environment by : Doeke Eisma
Download or read book Suspended Matter in the Aquatic Environment written by Doeke Eisma and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to give an introduction to the most important aspects of suspended matter in the aquatic environment: its origin and composition, the concentration distribution, transport and deposition, and the most important physical-chemical-bio logical process that affects suspended matter: flocculation. In Chap ter 1 the development of suspended matter observation and study throughout history is given, with the coming of a more modern approach during the 19th century and the first half of the 20th century, and the development of the present science of suspended matter after 1945. The sources of suspended matter in rivers, lakes, estuaries, and the sea are discussed in Chapter 2, which includes the supply of detrital particles as well as the formation of new particles in the water (organic matter, carbonate, opal). The concentration distribution of suspended matter in rivers, lakes, estuaries, tidal is discussed in Chapter 3, to which is areas, lagoons, and in the sea added a discussion on the sampling of suspended matter and on methods to determine its concentration. Particle composition is treated in Chapter 4, to which is added a section (4. 6) on the compositional analysis of suspended particles. Also included is a discussion on particle surface characteristics and the adsorption of elements and compounds onto particles.
