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.

River Mixing J. C. Rutherford NIWA Ecosystems, New Zealand Quantitative predictions of the rates of mixing of tracers (principally neutrally-buoyant tracers) in rivers are needed in a variety of situations including the preliminary design of outfalls, the impact assessment of discharges, water resource planning, and research on biological processes in rivers. River Mixing describes the theoretical basis for commonly-used mixing models, in order that the mixing equations being used are easily understood, and the correct mixing model is chosen for any given problem. Information from a variety of sources is collated to provide the user with a book which contains all the important elements: the theory; the models and solution methods for important river mixing problems; and the methods for determining mixing coefficients. Guidance is given when making rapid calculations for important mixing problems, and recent progress in the understanding of vertical and transverse mixing is discussed. The emphasis is placed on simple models which are invaluable for making rapid and relatively inexpensive appraisals of a mixing problem, although the more complex models, which may be used once a preliminary analysis has been completed, are also described. Covering all the key elements, River Mixing is essential reading for practising engineers, research scientists and technical managers of water resources.

"This book is a valuable theoretical resource for graduate students specialising in estuary processes and for researchers in related disciplines. It is also a useful guide for practitioners and consultants with its wide range of analytical equations, describing hydraulic, mixing and salt intrusion processes in estuaries."--Jacket.

The second edition of Environmental Oceanography is the first textbook to link the needs of the coastal oceanographer and the environmental practitioner. The ever-increasing human impact on the environment, and particularly on the coastal zone, has led governments to carefully examine the environmental implications of development proposals. This book provides the background needed to undertake coastal oceanographic investigations and sets them in context by incorporating case studies and sample problems based on the author's experience as an environmental consultant.

The book describes models of aquatic ecosystems, ranging from lakes to estuaries to the deep ocean. It provides a background in the physical and biological processes, numerical methods and elementary ecosystem models. It describes two of the most widely used hydrodynamic models and presents a number of case studies. The practice of modelling in management is discussed.

The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.

A derivative of the Encyclopedia of Inland Waters, Biogeochemistry of Inland Waters examines the transformation, flux and cycling of chemical compounds in aquatic and terrestrial ecosystems, combining aspects of biology, ecology, geology, and chemistry. Because the articles are drawn from an encyclopedia, they are easily accessible to interested members of the public, such as conservationists and environmental decision makers. This derivative text describes biogeochemical cycles of organic and inorganic elements and compounds in freshwater ecosystems.

This fascinating work is divided into two main sections. Part I reviews the basic principles of water movement in channels and the mass balance approach common to most models. It also covers the practical usefulness, model peer review, and guidance on model selection and calibration. Part II discusses flow simulation and prediction of time of travel, dye tracing and mixing, heat balance and temperature modeling, and reaeration and volatilization. This interesting, easy-to-read volume includes comprehensive reviews for the use of fluorescent water tracing dyes, longitudinal dispersion, evaporation and wind speed functions, prediction of saturation concentrations of dissolved oxygen, and reaeration coefficients. This book furnishes the reader with appendices which provide a synopsis of available computer models and gives a comprehensive listing of methods used to measure flow rates in rivers, tributaries, and pipes and channels introducing wastewaters into streams. This volume is a valuable, indispensable reference for all researchers, instructors, students in advanced environmental modeling courses, and practicing engineers.

What happens when a chemical is released into the environment? It diffuses, disperses, adsorbs, reacts, and/or changes state. To predict and analyze this process, the mathematics of diffusion is applied to lakes, rivers, groundwater, the atmosphere, the oceans, and transport between these media. A sustainable world requires a deep understanding of the transport of chemicals through the environment and how to address and harness this process. This volume presents a succinct and in-depth introduction to this critical topic. Featuring authoritative, peer-reviewed articles from the Encyclopedia of Sustainability Science and Technology, Transport and Fate of Chemicals in the Environment represents an essential one-stop reference for an audience of researchers, undergraduate and graduate students, and industry professionals.
