Various methods of system simulation and optimization are applied in a number of case studies. Methods of analysis and numerical methods are described, as well as the basis of pollution and water quality. The economics of desalination are also discussed. The examples studied range from regional supplies to internal re-circulation. Groundwater and artificial recharge are considered, and stormwater quality and sewerage systems are also covered. Computer applications exist throughout and a number of simulation and optimization programs in BASIC are presented. The necessity for scientific sampling procedures in monitoring water quality, an often ignored subject, was written by Professor Tom Sanders of Colorado State University.
The theory and case studies should prove of value in many aspects of planning the use of water resources with quality constraints. Wastewater re-use and conservation are therefore promoted by the approach adopted.
This classic monograph has been revised and updated to take account of new developments in the field. Recent research in cavitation and flow control has prompted additional sections to be added. There are also new sections on supports to exposed pipes and secondary stress. Additional references and a new layout make up this edition. Some sections appearing in previous editions, noteably on pipe network systems analysis and optimization have been ommitted as they were considered more appropriate in the author's parallel book ``Pipeflow Analysis'' (Developments in Water Science, 19).
Some of the problems experienced in building water resources in developing countries are described in this book, and methods of solution based on the limited experience of the authors, are offered. These range from use of unbiased common sense, coupled with a close understanding of people's requirements, to a comprehensive computer simulated planning model. Some types of water resources development are described in more detail. These include irrigation, hydro electric power and rural water supply. Sections on socio-economics and human resource development are also included, as well as on data collection, and project planning. Lessons from the failure of multimillion dollar projects are not hard to come by, and examples and pointers which will assist future planners are given. Attention is paid to the need for aid to include training and to stimulate local economies. However big water projects appear, they cannot escape the effects of the rest of the country's economy. Attention is also drawn to environmental problems, particularly soil erosion, often caused by water resources development. The fact that water resources development cannot be carried out by engineers only, is recognized. The input of many professions, and vast experience, is needed.
Drawn on international case studies, much of the material has been presented in postgraduate courses by the authors.
Robert Glennon captures the irony—and tragedy—of America’s water crisis in a book that is both frightening and wickedly comical. From manufactured snow for tourists in Atlanta to trillions of gallons of water flushed down the toilet each year, Unquenchable reveals the heady extravagances and everyday inefficiencies that are sucking the nation dry.
The looming catastrophe remains hidden as government diverts supplies from one area to another to keep water flowing from the tap. But sooner rather than later, the shell game has to end. And when it does, shortages will threaten not only the environment, but every aspect of American life: we face shuttered power plants and jobless workers, decimated fi sheries and contaminated drinking water.
We can’t engineer our way out of the problem, either with traditional fixes or zany schemes to tow icebergs from Alaska. In fact, new demands for water, particularly the enormous supply needed for ethanol and energy production, will only worsen the crisis. America must make hard choices—and Glennon’s answers are fittingly provocative. He proposes market-based solutions that value water as both a commodity and a fundamental human right.
One truth runs throughout Unquenchable: only when we recognize water’s worth will we begin to conserve it.

The Columbia River Treaty: A Primer is a vital work that clearly explains the nature of this complex water agreement between Canada and the United States and how its impending update will impact communities, landscapes, industry and water supplies between the two countries for many years to come.
The Columbia River Treaty ratification in 1964 created the largest hydropower project in North America, with additional emphasis on flood protection for the USA. As the Treaty approaches its 60th anniversary, and the first opportunity for modification, its signatories are preparing proposals for new ways forward, and stakeholders on both sides of the border are speaking up.
This primer explores the initial intent of the Treaty and its success to date, its costs to Columbia Basin residents and ecosystems, and new influences the signatories must now consider. Shifts in social norms related to the environment, equity and social justice, new views on the relevance of Indigenous traditional and local knowledge, and the economic and physical effects of a changing climate – are all considered as factors in future Treaty governance. The primer concludes with a summary of the perspectives that currently exist between and within each country with respect to Treaty benefits and outlines the next steps that will take place in the negotiation process. The authors conclude with a call to action, in the hope that a renewed Columbia River Treaty might prove a model for outstanding transboundary water agreements around the world as they strive to meet not only the challenges of the present day but also the needs of future generations.

The Committee on Hydrologic Science was established by the National Research Council in 1999 to identify priorities for hydrologic science that will ensure its vitality as a scientific discipline in service of societal needs. This charge will be performed principally through a series of studies that provide scientific advice on the hydrologic aspects of national program and U.S. hydrologic contributions to international programs.
This first report contains a preliminary assessment of the hydrologic science content of the U.S. Global Change Research Program (USGCRP). Because this is a short and focused report, little effort is spent to reaffirm the established and successful elements of the USGCRP. In fact, the Committee generally endorses the findings of the National Research Council (NRC) report Global Environmental Change: Research Pathways for the Next Decade (NRC, 1998a; the so-called Pathways report) in this respect. Instead the attention here is directed toward the most critical missing hydrologic science elements in the FY2000 USGCRP. This brings the focus to the terrestrial component of the water cycle. The integrative nature of terrestrial hydrology could significantly strengthen the USGCRP.

This book is addressed to university students of geology especially engineering geology and hydrogeology, geophysics and earth sciences, and post graduate, reseachers, and practising engineering geologists, geotechnical engineers, and hydrogeologists.
As opposed to more theoretical works, this is a catalog of possible engineering interventions in karst and their implications. Although the majority of readers will be professionals with geology/hydrogeology backgrounds, the language is not purely technical making it accessible to a wider audience. This means that the methodology, case studies and experiences presented will also benefit water managers working in karst environments.
Individually these principles and practices are not new, but in combination they describe an innovative approach for addressing complex water and related management issues. This recommended process consists of a series of four basic phases; Assessment, Planning, Implementation, and Evaluation, which are built on stakeholder involvement, social capacity, and adequate monitoring. This four-phased approach will assist watershed practitioners develop a plan consistent with the recently released USDA-EPA Watershed Management Planning and Implementation Process guidance. This process can be used to implement a management strategy to meet the load allocations required by an approved Total Maximum Daily Load (TMDL), the goals of a Source Water Protection Plan, USDA programs such as EQIP, or Section 319 Project.
The process outlined in the text is applicable for both restoration and prevention projects. The Watershed Project Management Guide focuses on the complexities of the watershed management process, the watershed partnership's role in the processes, and what needs to be done next. The author has kept the technical jargon to a minimum to help the reader easily grasp the important points and where appropriate directs the reader to specific resources and references for further information.
