Download or read book Groundwater Modelling in Arid and Semi Arid Areas written by Howard S. Wheater and published by Cambridge University Press. This book was released on 2010-09-09 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.

Download or read book Soil and Water Contamination written by Marcel van der Perk and published by CRC Press. This book was released on 2017-10-09 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and Water Contamination, Second Edition gives a structured overview of transport and fate processes of environmental contaminants. Providing a structured overview of transport and fate processes of environmental contaminants, this textbook approaches the environmental issues of soil and water contamination from a spatial and earth science point of view. The new edition contains new material on pesticides and pharmaceutical contaminants and a greater number of exercises, case studies, and examples. It covers topics essential to understanding and predicting contaminant patterns in soil, groundwater, and surface water and contributes to the formation of a solid basis for adequate management and control of soil and water pollution and integrated catchment.

Download or read book Dams and Geomorphology written by P.J. Beyer and published by Elsevier. This book was released on 2005-12-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dams profoundly impact the geomorphology of rivers by altering the natural patterns of water, sediment and energy flow in rivers. These changes have a largely negative impact on aquatic and riparian ecosystems upstream and downstream of the dam. Natural dams also impact river geomorphology, although with positive and negative repercussions for aquatic and riparian organisms. In 2002, the 33rd Binghamton Geomorphology Symposium convened under the theme "Dams and Morphology," and featured invited papers and contributed posters on topics of natural dams, artificial dams, and dam removal. Fourteen of these papers have been included in this volume.

Download or read book The Great Lakes Restoration Initiative written by Óskar Strobel and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Lakes ecosystem is recognised by many as an international natural resource that has been altered by human activities and climate variability. These alterations have led to degraded water quality, diminished habitat, lower native fish and wildlife populations, and an altered ecosystem. In response, the federal governments of the United States and Canada and the state and provincial governments in the Great Lakes basin are implementing several restoration activities. These activities range from mitigating the harmful effects of toxic substances in lake waters to restoring fish habitat. This books provides the reader with a background on and issues of the Great Lakes restoration initiative, as well as the action plan for the years 2010-2014.

This book was released on 2003 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of Canadian water quality guidelines for the nitrate ion for the protection of aquatic life. It contains a review of technical background information on the chemical & physical properties of nitrate & nitrate salts, the nitrogen cycle, natural & anthropogenic sources, fate & behaviour of nitrate in the environment, nitrate environmental concentrations, and effects of nitrates on aquatic organisms (including fish, plants, invertebrates, and semi-aquatic mammals & birds). The final section sets out nitrate concentration guidelines to protect fresh & marine water quality and aquatic life, and provides guidance on the application of the guidelines. Appendices include tables that summarize freshwater & marine toxicity studies.

Download or read book Assessing the TMDL Approach to Water Quality Management written by National Research Council and published by National Academies Press. This book was released on 2001-08-24 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last 30 years, water quality management in the United States has been driven by the control of point sources of pollution and the use of effluent-based water quality standards. Under this paradigm, the quality of the nation's lakes, rivers, reservoirs, groundwater, and coastal waters has generally improved as wastewater treatment plants and industrial dischargers (point sources) have responded to regulations promulgated under authority of the 1972 Clean Water Act. These regulations have required dischargers to comply with effluent-based standards for criteria pollutants, as specified in National Pollutant Discharge Elimination System (NPDES) permits issued by the states and approved by the U.S. Environmental Protection Agency (EPA). Although successful, the NPDES program has not achieved the nation's water quality goals of "fishable and swimmable" waters largely because discharges from other unregulated nonpoint sources of pollution have not been as successfully controlled. Today, pollutants such as nutrients and sediment, which are often associated with nonpoint sources and were not considered criteria pollutants in the Clean Water Act, are jeopardizing water quality, as are habitat destruction, changes in flow regimes, and introduction of exotic species. This array of challenges has shifted the focus of water quality management from effluent-based to ambient- based water quality standards. Given the most recent lists of impaired waters submitted to EPA, there are about 21,000 polluted river segments, lakes, and estuaries making up over 300,000 river and shore miles and 5 million lake acres. The number of TMDLs required for these impaired waters is greater than 40,000. Under the 1992 EPA guidance or the terms of lawsuit settlements, most states are required to meet an 8- to 13-year deadline for completion of TMDLs. Budget requirements for the program are staggering as well, with most states claiming that they do not have the personnel and financial resources necessary to assess the condition of their waters, to list waters on 303d, and to develop TMDLs. A March 2000 report of the General Accounting Office (GAO) highlighted the pervasive lack of data at the state level available to set water quality standards, to determine what waters are impaired, and to develop TMDLs. This report represents the consensus opinion of the eight-member NRC committee assembled to complete this task. The committee met three times during a three-month period and heard the testimony of over 40 interested organizations and stakeholder groups. The NRC committee feels that the data and science have progressed sufficiently over the past 35 years to support the nation's return to ambient-based water quality management. Given reasonable expectations for data availability and the inevitable limits on our conceptual understanding of complex systems, statements about the science behind water quality management must be made with acknowledgment of uncertainties. This report explains that there are creative ways to accommodate this uncertainty while moving forward in addressing the nation's water quality challenges.
