Download or read book Water Quality Indices written by Tabassum Abbasi and published by Elsevier. This book was released on 2012-03-10 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

Download or read book Irrigation Induced Water Quality Problems written by National Research Council and published by National Academies Press. This book was released on 1989-02-01 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"â€"trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures. This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.

Download or read book Turfgrass and Landscape Irrigation Water Quality written by Robert N. Carrow and published by CRC Press. This book was released on 2008-12-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the increased use of alternative irrigation water sources on turfgrass and landscape sites, their management is becoming more complex and whole ecosystems-oriented. Yet few turfgrass managers have received formal training in the intricacies of irrigation water. Turfgrass and Landscape Irrigation Water Quality: Assessment and Management provides a comprehensive, science-based review of irrigation water quality. The book examines field problems in a logical manner, provides clear scientific explanations, and offers detailed practical information for resolving each specific problem in an environmentally sustainable manner. Divided into four parts, the book begins with an overview of the assessment of irrigation water. It discusses factors that affect the quality of water, assists readers in understanding irrigation water quality tests, and examines field monitoring. The second part focuses on explaining scientific irrigation water quality situations or challenges associated with various water sources, including saline, seawater, and reclaimed irrigation water, as well as stormwater reuse. The next section explores management options for site-specific problems. The authors discuss irrigation system design when confronted with poor quality water, salt leaching, water acidification, and turfgrass nutritional considerations, and discusses lake, pond, and stream management and other water issues. Lastly, the text addresses potential environmental concerns related to irrigation water sources on the watershed/landscape level. The book contains several case studies which further clarify the material and provides a comprehensive appendix list of landscape plants and their relative salinity tolerances. The diversity and nature of various water quality related challenges are quite daunting, even for the most seasoned professional. This volume provides a foundation for understanding the complexities of water quality that is certain to lead to science-based management decisions that are environmentally friendly and sustainable for years to come.
Download or read book Confronting the Nation s Water Problems written by National Research Council and published by National Academies Press. This book was released on 2004-10-14 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to confront the increasingly severe water problems faced by all parts of the country, the United States needs to make a new commitment to research on water resources. A new mechanism is needed to coordinate water research currently fragmented among nearly 20 federal agencies. Given the competition for water among farmers, communities, aquatic ecosystems and other users-as well as emerging challenges such as climate change and the threat of waterborne diseases-Confronting the Nation's Water Problems concludes that an additional $70 million in federal funding should go annually to water research. Funding should go specifically to the areas of water demand and use, water supply augmentation, and other institutional research topics. The book notes that overall federal funding for water research has been stagnant in real terms for the past 30 years and that the portion dedicated to research on water use and social science topics has declined considerably.
