This book was released on 2022-10-28 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Les actes de ces journées font état de réflexions, tant en France qu'à l'étranger, sur la restauration de marais, d'estuaires, de baies et de lagunes, incluant l'incidence sur les espèces et ressources. L'ouvrage regroupe une sélection des communications présentées devant un public de scientifiques, enseignants, aménageurs professionnels de la mer et conservateurs du littoral. Y sont présentés quelques grands chantiers (lagunes de Venise et de Tunis, baie du Mont-Saint-Michel, estuaire de Seine...), ainsi que des réalisations de tailles et de natures diverses. Des aspects particuliers de la biorestauration sont abordés au travers du traitement biologique des vases, ou celui des pollutions par hydrocarbures. Les aspects technico-économiques s'appuient sur des exemples accidentels ou naturels. Les aménageurs et les sociétés d'ingénierie écologique pourront trouver, dans ces documents, critères et méthodes d'évaluation scientifique pour quantifier les coûts de restauration d'écosystèmes en fonction de l'importance des " dégâts ".

This book was released on 2004 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this study was to develop a strategy for monitoring environmental effects at a single exploratory offshore well on the east coast. Work carried out in the study consisted of consultations with scientists, regulators, & stakeholders; reviews of regulatory regimes; toxicity results relevant to exploratory activities; and development of a decision tree for determining when & how to conduct environmental effects monitoring (EEM). The study report first presents background on potential issues related to the environmental impacts of exploratory drilling, the characteristics of typical exploratory drill rigs & drilling muds, the regulatory regime in Canada & elsewhere, and the biological & other effects of drilling. It then summarizes EEM programs & their results for exploratory wells on the Scotian Shelf & Grand Banks; outlines EEM issues of concern for the Newfoundland & Nova Scotia offshore, and discusses issue similarities & differences between the two areas; and draws brief conclusions on the application of production EEM experience to exploratory drilling EEM. Finally, an EEM decision process based on three scenarios appropriate to the east coast is presented, along with recommended study designs to address the scenarios.

This book was released on 2013-05-01 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: Au regard du Code de l’environnement, les digues, considérées comme ouvrages hydrauliques, ne doivent pas rompre de façon dangereuse pour les populations. En tant que moyen de prévention du risque d’inondation ou de submersion, les performances et les limites de ces digues doivent être connues avec précision. Les digues de protection constituent donc une question politique mise en évidence par plusieurs événements récents (Xynthia 2010, la NouvelleOrléans 2005, Rhône aval 2003, Gard 2002, Aude 1999). Cet ouvrage rassemble les contributions présentées lors du 2e colloque national Digues maritimes et fluviales de protection contre les submersions (Digues2013), organisé par l’Irstea et Promosciences, les 12, 13 et 14 juin 2013 au Centre des Congrès d’AixenProvence, avec le soutien du MEDDE, du CFBR, et de la Région ProvenceAlpesCôte d’Azur. Il s’adresse aux maîtres d’ouvrages, gestionnaires, concepteurs, constructeurs, enseignants et chercheurs, services de contrôle, organismes financeurs, agissant dans les domaines d’activités liés, directement ou indirectement, à la sûreté des digues maritimes et fluviales.
