Book Description
Dams are planned, constructed, and operated to meet human needs - generation of energy, irrigated agricultural production, flood control, public and industrial supply, supply of drinking water, and various other purposes. Dams impound water in reservoirs during times of high flood that can be used for human requirements during times with inadequate natural flows. Positive impacts of dams are improved flood control, improved welfare resulting from new access to irrigation and drinking water. Without dams there would be insufficient food to feed the world’s people and energy would be generated by burning fossil fuels that produce greenhouse gases. Despite this progress there remain significant concerns about the environmental impacts of dams. These environmental impacts are complex and far reaching, remote of the dam, and may occur in time with the dam construction or later and may lead to a loss of biodiversity and of productivity of natural resources. This bulletin compiles improvements in knowledge and state of the art technology to avoid or mitigate environmental impacts of dams on the natural ecosystem as well as to the people that depend upon them for their livelihood and also addresses the mitigation of environmental impacts on dams and reservoirs. Les barrages sont planifiés, construits et exploités de manière à répondre aux besoins humains. Les barrages retiennent l'eau dans les réservoirs pendant les périodes de forte crue, une eau qui peut être utilisée pour les besoins de l'homme pendant les périodes d’insuffisance des débits naturels. Les impacts positifs de barrages sont le contrôle des crues et l'amélioration du bien-être résultant du nouvel accès à l'irrigation et à l'eau potable. Sans barrages, la production alimentaire serait insuffisante pour nourrir la population du globe et l'énergie serait générée en brûlant des combustibles fossiles qui produisent des gaz à effet de serre. Malgré ces progrès, d'importantes préoccupations subsistent quant aux retombées des barrages sur l’environnement. Les impacts environnementaux sont complexes et d’une grande portée. Ils peuvent se produire au moment de la construction du barrage ou plus tard et peuvent entraîner une perte de la biodiversité et de la productivité des ressources naturelles. Le présent bulletin compile l'amélioration des connaissances et des technologies les plus récentes pour éviter ou atténuer les impacts environnementaux des barrages sur l'écosystème naturel ainsi que pour les personnes qui en dépendent pour leur subsistance. Il aborde également l'atténuation des impacts environnementaux sur les barrages et les réservoirs.

Book Description
"This paper briefly outlines the physical nature of water resources and the problems and conflicts associated with their use, and goes on to outline the structures and policies that Canadian governments have devised to deal with them. The interrelated nature of federal and provincial jurisdictions over subjects that affect water resources is also described"--Abstract.

Book Description
This volume contains selected up-to-date professional papers prepared by specialists from various disciplines related to geosciences and water resources. Thirty papers discuss different aspects of environmental data modeling. It provides a forum bringing together contributions, both theoretical and applied, with special attention to Water in Ecosystems, Global Atmospheric Evolution, Space and Earth Remote Sensing, Regional Environmental Changes, Accessing Geoenvironmental Data and Ecotoxicological Issues. "Geosciences and Water Resources: Environmental Data Modeling" is now the fourth volume in the Series "Data and Knowledge in a Changing World". Launched by CODATA after the 14th International Conference of the Committee on Data for Sciences and Technology, in Chambery, the purpose of this new Series is to collect from widely varying fields a wealth of information pertaining to the intelligent exploitation of data in science and technology and to make that information available to a multidisciplinary community. The present series encompasses a broad range of contributions, including computer-related handling and visualization of data, to the major scientific, tech nical, medical and social fields. The titles of the previous published volumes are: The Information Revolution: Impact on Science and Technology. Modeling Complex Data for Creating Information. Industrial Information and Design Issues.
