Available in PDF, EPUB and Kindle. Book excerpt: Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources. The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies. The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Download or read book Colorado River Basin Water Management written by National Research Council and published by National Academies Press. This book was released on 2007-06-30 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies of past climate and streamflow conditions have broadened understanding of long-term water availability in the Colorado River, revealing many periods when streamflow was lower than at any time in the past 100 years of recorded flows. That information, along with two important trends-a rapid increase in urban populations in the West and significant climate warming in the region-will require that water managers prepare for possible reductions in water supplies that cannot be fully averted through traditional means. Colorado River Basin Water Management assesses existing scientific information, including temperature and streamflow records, tree-ring based reconstructions, and climate model projections, and how it relates to Colorado River water supplies and demands, water management, and drought preparedness. The book concludes that successful adjustments to new conditions will entail strong and sustained cooperation among the seven Colorado River basin states and recommends conducting a comprehensive basinwide study of urban water practices that can be used to help improve planning for future droughts and water shortages.

Download or read book The Evolution of National Water Regimes in Europe written by Stefan Kuks and published by Springer Science & Business Media. This book was released on 2013-06-05 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: All over the world countries struggle with water stress. Problems vary from water scarcity and a degrading water quality, to floods and a rising sea level due to climate change. The European Union adopted a Water Framework Directive to improve the sustainability of water management in its member states. Water management should be coordinated at the level of river basins as a whole. Interests of various user groups should be better represented. River basin visions should take into account the impact of all human activities on the status of the resource. Water legislation needs streamlining and more focus on its implementation. The European Union advocates regulating water prices by charging the costs of water services on the basis of full cost recovery and the polluter pays principle. This book examines the development of water management in the Netherlands, Belgium, France, Spain, Italy and Switzerland. It is based on the European research project EUWARENESS. The authors apply a theoretical framework for the analysis of institutional regimes, water governance and property rights. The evolution of national water resource regimes is described over a period of almost 200 years (1800-2000). The long-term perspective enables the reader to see the conditions under which regime transformation and paradigm change are made possible. The book also includes a critical analysis of policy making by the European Union, and a comparative review and analysis of regime development in the six countries involved. This book is followed by another volume published with Kluwer Academic Publishers on "Integrated Governance and Water Basin Management", edited by Hans Bressers and Stefan Kuks.

This book was released on 2018-08-16 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates of water withdrawals enable the depiction of trends in total water use for the Nation among different geographic areas, categories of use, and sources over time. Water-use information is a critical component of water budgets, which are essential to surface- water and groundwater availability studies. This information is also essential to accurately understand how future water demands will be met while maintaining adequate water quality and quantities for human and ecosystem needs across the United States of America. Data is represented in text abstracts and analysis, tables, chart graphics, and photos presented throughout. The estimates contained within this volume focus on water use for eight (8) categories: Public Supply * Irrigation Self-supplied Domestic * Livestock Aquaculture * Industrial Mining * Thermoelectric Power Related products: Other products produced by the U.S. Geological Survey (USGS) are available here: https://bookstore.gpo.gov/agency/us-geological-survey-usgs Check out our Water Management resources collection here: https://bookstore.gpo.gov/catalog/water-management
Download or read book Colorimetric Determination of Nitrate Plus Nitrite in Water by Enzymatic Reduction Automated Discrete Analyzer Methods written by Charles J Patton and published by CreateSpace. This book was released on 2014-06-16 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents work at the U.S. Geological Sur- vey (USGS) National Water Quality Laboratory (NWQL) to validate enzymatic reduction, colorimetric determinative meth- ods for nitrate + nitrite in filtered water by automated discrete analysis. In these standard- and low-level methods (USGS I-2547-11 and I-2548-11), nitrate is reduced to nitrite with nontoxic, soluble nitrate reductase rather than toxic, granular, copperized cadmium used in the longstanding USGS auto- mated continuous-flow analyzer methods I-2545-90 (NWQL laboratory code 1975) and I-2546-91 (NWQL laboratory code 1979). Colorimetric reagents used to determine resulting nitrite in aforementioned enzymatic- and cadmium-reduction meth- ods are identical. The enzyme used in these discrete analyzer methods, designated AtNaR2 by its manufacturer, is produced by recombinant expression of the nitrate reductase gene from wall cress (Arabidopsis thaliana) in the yeast Pichia pastoris. Unlike other commercially available nitrate reductases we evaluated, AtNaR2 maintains high activity at 37°C and is not inhibited by high-phenolic-content humic acids at reaction temperatures in the range of 20°C to 37°C. These previously unrecognized AtNaR2 characteristics are essential for success- ful performance of discrete analyzer nitrate + nitrite assays (henceforth, DA-AtNaR2) described here.

This book was released on 2005-06-18 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. This new report, the sixth in a series of reports presenting dietary reference values for the intakes of nutrients by Americans and Canadians, establishes nutrient recommendations on water, potassium, and salt for health maintenance and the reduction of chronic disease risk. Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate discusses in detail the role of water, potassium, salt, chloride, and sulfate in human physiology and health. The major findings in this book include the establishment of Adequate Intakes for total water (drinking water, beverages, and food), potassium, sodium, and chloride and the establishment of Tolerable Upper Intake levels for sodium and chloride. The book makes research recommendations for information needed to advance the understanding of human requirements for water and electrolytes, as well as adverse effects associated with the intake of excessive amounts of water, sodium, chloride, potassium, and sulfate. This book will be an invaluable reference for nutritionists, nutrition researchers, and food manufacturers.
