Download or read book The Winter Hydrologic Regime of the Nechako River British Columbia written by S. P. Blachut and published by . This book was released on 1988 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: All historical winter (November-April) hydrologic data for the Nechako River were compiled and a 66-year record of air temperature data for Vanderhoof was used as an index of severity of winter. A simple water temperature model based on air temperature was used to predict cooling of river water to 0 C under different meteorological and hydrological conditions. A simple predictive model of the progression of surface ice, based on air temperature, was developed. Two years of water temperature and ice observations on the Nechako River were used to calibrate the models and document ice conditions in chinook spawning areas. The effects of winter hydrologic conditions on the intragravel environment and the risks of overwintering chinook eggs and alevins are assessed.

Book excerpt: AWARDS:2006 Outstanding Academic Title, by CHOICEThe 2005 Award for Excellence in Professional and Scholarly Publishing by the Association of American Publishers (AAP) Best Reference 2005, by the Library JournalRivers of North America is an important reference for scientists, ecologists, and students studying rivers and their ecosystems. It brings together information from several regional specialists on the major river basins of North America, presented in a large-format, full-color book. The introduction covers general aspects of geology, hydrology, ecology and human impacts on rivers. This is followed by 22 chapters on the major river basins. Each chapter begins with a full-page color photograph and includes several additional photographs within the text. These chapters feature three to five rivers of the basin/region, and cover several other rivers with one-page summaries. Rivers selected for coverage include the largest, the most natural, and the most affected by human impact. This one-of-a-kind resource is professionally illustrated with maps and color photographs of the key river basins. Readers can compare one river system to another in terms of its physiography, hydrology, ecology, biodiversity, and human impacts. * Extensive treatment provides a single source of information for North America's major rivers* Regional specialists provide authoritative information on more than 200 rivers* Full-color photographs and topographical maps demonstrate the beauty, major features, and uniqueness of each river system* One-page summaries help readers quickly find key statistics and make comparisons among rivers

This book was released on 1993 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Recognizing the lack of comprehensive information on river ice environmental problems, the National Research Council of Canada's Subcommittee on Hydraulics of Ice Covered Rivers recommended in 1988 that a Task Force be form to investigate the environmental aspects of river ice. The Task Force has assembled this state-of-the-art report in order to document current knowledge and develop recommendations for research. ... This state-of-the-art report comprises contributions by Task Force members and is organized under three major chapters: physical, chemical and biological. The editors have re-arranged original material and inserted new text to enhance the degree of coverage, to maximize consistency among authors' presentations, and to better link the various sections. A subsequent publication "Proceedings of the Workshop on Environmental Aspects of River Ice" will be published following the release of this science report at the workshop of the same name"--Introduction, pages 1-2.
