Introduction to Water Resources and Environmental Issues
How much water does the world need to support growing human populations? What are the potential effects of climate change on the world's water resources? These questions and more are discussed in this thoroughly updated and expanded new edition. Written at the undergraduate level, this accessible textbook covers the fundamentals of water resources, water law, allocation, quality and quantity, health issues, and provides examples of potential personal actions and solutions. There is a keener focus on climate change, as many of the predictions made in the first edition have now come to pass. This new edition features improved artwork, more active learning prompts, more positive examples of beneficial changes, basic introductions to scientific approaches and a discussion of emerging contaminants and LiDAR technology. It contains strong teaching features, with new 'In Depth' and 'Think About It' sections to encourage class discussion, and homework questions to test students' understanding.
Introduction to Water Resources and Environmental Issues
How much water does the world need to support growing human populations? What factors influence water quality, droughts, floods, and waterborne diseases? What are the potential effects of climate change on the world's water resources? These questions and more are discussed in this thorough introduction to the complex world of water resources. The strength of the book is its coverage of the fundamentals of the science of water, aquatic ecology, geomorphology and hydrology, supplemented by internet resources and examples from water resource issues in the news to engage the student. The book begins with a short history of human use and influence on water, followed by chapters on the geomorphology, hydrology, chemistry, and biology of lakes, rivers, and wetlands. Major disease issues, worldwide water quality and quantity problems, and potential solutions are addressed. Water laws, water allocation, and the conflicts involved are discussed using US and international examples. Students in departments of environmental studies, life science, Earth science, and engineering will benefit from this broad survey of these crucial issues.
Environmental Security and India
This book examines environmental issues through the lens of security studies and presents a comprehensive analysis of Indian policy in dealing with threats posed by climate change. This book: Puts forward theoretical base for securitization of environmental issues, incorporating different schools of thought; Presents a survey of global environmental politics in general and the effects of climate change and its consequences for India's national security in particular; Examines the politics involved in India's environmental policy at both the domestic and international levels; Outlines key policy takeaways and possibilities for action that can help contain the threat of environmental change. A comprehensive guide to a new and emerging dimension in Indian security policy, this book will be essential reading for students and researchers of international relations, security studies, especially non-traditional security, public policy, especially environmental policy; and area studies.
Downriver
The Green River, the most significant tributary of the Colorado River, runs 730 miles from the glaciers of Wyoming to the desert canyons of Utah. Providing water for thirty-three million people, it flows through ranches, cities, national parks, and some of the most significant natural gas fields in the country. Stopped up by dams, slaked off by irrigation, and dried up by cities, the Green is crucial, overused, and at risk, now more than ever. Fights over the river's water, and what's going to happen to it in the future, are long-standing, intractable, and only getting worse as the West gets hotter and drier and more people depend on the river with each passing year.

Drinking Water Quality
This textbook provides a comprehensive review of the problems associated with the supply of drinking water in the developed world. Since the first edition of this book was published, water companies and regulators have been presented with numerous new challenges - global warming has seriously affected water supplies and water quality; advances in chemical and microbial analysis have revealed many new contaminants in water that were previously undetectable; and recent terrorist attacks have demonstrated how vulnerable water supplies are to contamination or disruption. This new edition includes an overview of the current and emerging problems, with potential solutions. It has been completely updated, and includes the WHO Revised Drinking Water Guidelines. An ideal textbook for courses in environmental science, hydrology, environmental health and environmental engineering; it also provides an authoritative reference for practitioners and professionals in the water supply industry.
Wasser
Die knappe und gleichzeitig nicht austauschbare Ressource Wasser steht derzeit im Zentrum öffentlicher und wissenschaftlicher Debatten. Erfolge in der Lösung von Wasserversorgung und Vermeidung von Flutkatastrophen vermindern Sterbeziffern, soziale und globale Ungleichheiten, und können helfen, politischen Einfluss und Märkte zu stärken. Auch in der Vergangenheit waren erfolgreicher Umgang mit Wasser und damit verbundene aufwendige hydraulische Anlagen Zeichen von erfolgreicher ziviler Herrschaft. Im Zentrum der sechs Beiträge dieses Bandes aus Antike, Neuzeit und Moderne steht der Zusammenhang von Natur, Technik, Ästhetik und Repräsentationswillen staatlicher Herrschaftsträger, der sich, wie die Autoren argumentieren, ganz besonders in Wasserbauten zeigt. Im historischen Vergleich wird deutlich, welche Probleme eine stabile Wasserversorgung zu allen Zeiten ökologisch darstellte, deren Lösung Menschen, Geld und staatliches Know-how mobilisierte und gleichzeitig Konkurrenzen und kompetitive Herrschaftsrepräsentation in der Auseinandersetzung mit Gegenwarten und Vergangenheiten zum Ausdruck brachte.
Environmental Compartments
Any concentration of a substance measured in a living or non-living system results from its distribution among all of the environmental compartments: air, water, sediments, and biota. The transfer of a substance from one compartment to another is regulated by physical forces and the chemical properties of the substance and also those of the compartments. When transfer processes are nearly constant in time, a substance will achieve predictable equilibria distributions. It is of utmost importance that students, environmental scientists, and policymakers understand the basic processes which control the distribution of a substance in order to interpret measurements obtained from within a limited number of compartments.
Biomonitoring of Water and Waste Water
Biomonitoring of water quality is very much essential for assessing the overall health of water bodies and safe supply of drinking water. The chemical nature of toxicant is highly dynamic in environment with time and space whereas biological system can integrate all environmental variables over a large period of time in terms of effect that can be easily measured and quantified. In view of the above, there is a pressing need to determine the water quality of natural resources as well as drinking water based on the standard protocols and guidelines from regulatory agencies. It is clear that the synthetic chemicals are essential for our society to maintain the health and well being of the people. However, there has been a range of detrimental effects on human health and natural environment. In general, we need to improve our management of waste chemicals discharged into the air, water and soil environments. New techniques are needed to predict adverse effects before they occur and for the treatment of wastes. In addition, a range of social, political and economic factors will be needed to be taken into account in order to achieve success.
Geochemical and Biogeochemical Reaction Modeling
This book provides a comprehensive overview of reaction processes in the Earth's crust and on its surface, both in the laboratory and in the field. A clear exposition of the underlying equations and calculation techniques is balanced by a large number of fully worked examples. The book uses The Geochemist's Workbench® modeling software, developed by the author and already installed at over 1000 universities and research facilities worldwide. Since publication of the first edition, the field of reaction modeling has continued to grow and find increasingly broad application. In particular, the description of microbial activity, surface chemistry, and redox chemistry within reaction models has become broader and more rigorous. These areas are covered in detail in this new edition, which was originally published in 2007. This text is written for graduate students and academic researchers in the fields of geochemistry, environmental engineering, contaminant hydrology, geomicrobiology, and numerical modeling.
