Introductory technical guidance for civil engineers and other professional engineers and construction managers interested in decommissioning of dams and related infrastructure. Here is what is discussed: 1. INTRODUCTION, 2. ECONOMIC THEORY OF DAM DECOMMISSIONING, 3. CATEGORIES OF IMPACT, 4. SUMMARY & CONCLUSIONS.

Dam decommissioning or dam removal has been increasingly common since the past decade. The reason for considering dam removal may have to do with the safety of dams, high repair costs, high operating and maintenance costs, or effects on fish passage and water quality. However, the decision to remove a dam must be based on careful evaluation of the alternatives to address the specific problem at each dam. The ICOLD Committee for decommissioning dams was established in 2005 to develop information that can be used by ICOLD members to respond to questions about the dismantling of dams and to provide a forum for the exchange of information . This ICOLD Bulletin is not intended as a design guide, but as a guide to the decision making process, consultation and regulatory approvals, design and construction issues, sediment management and performance monitoring. The primary aim of these Dam decommissioning guidelines is to provide dam owners, dam engineers and other professionals with the information needed to guide decision making when considering dam dismantling as a project alternative. They are not meant to be used as a design guide, but as a guide to highlighting the points of interest. The guidelines in this ICOLD Bulletin apply only to flood defense structures and not to fall dams.

Partnership, says Brinkerhoff (public administration, George Washington U.) is the polite term for minimizing the responsibility of government in development projects. She seeks to clarify the concepts and its practice, to critique the understanding and practice of it in international development to date, and to specify its defining dimensions.

The Missouri River Ecosystem: Exploring the Prospects for Recovery resulted from a study conducted at the request of the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. The nation's longest river, the Missouri River and its floodplain ecosystem experienced substantial environmental and hydrologic changes during the twentieth century. The context of Missouri River dam and reservoir system management is marked by sharp differences between stakeholders regarding the river's proper management regime. The management agencies have been challenged to determine the appropriate balance between these competing interests. This Water Science and Technology Board report reviews the ecological state of the river and floodplain ecosystem, scientific research of the ecosystem, and the prospects for implementing an adaptive management approach, all with a view toward helping move beyond ongoing scientific and other differences. The report notes that continued ecological degradation of the ecosystem is certain unless some portion of pre-settlement river flows and processes were restored. The report also includes recommendations to enhance scientific knowledge through carefully planned and monitored river management actions and the enactment of a Missouri River Protection and Recovery Act.

The focus of municipalities has been on the supply of sufficient water quantities to the public with less attention paid to water quality. The deteriorating quality of raw water sources necessitates increased attention to water quality with professional scientists playing a central role at municipalities and water boards together with professional engineers. With many stringent regulations on the quality of drinking water and recreational water bodies, the young municipal chemist needs a handy manual to assist in the often neglected and complicated field of municipal water management. Grounded in Science, Introduction to Municipal Water Quality Management not only links theory and regulations in practice but also offers simple numerical examples to better understand the rules and encourage a quantitative application to everyday problems. Developed from a series of lectures between 2015 and 2019, Introduction to Municipal Water Quality Management will give young professionals the confidence to analyse their results and apply their knowledge in a numerical fashion.

Focusing on reservoir sedimentation management and control, this work defines the nature and severity of sedimentation, reviews relevant physical processes, describes techniques used to combat sedimentation, and presents detailed case studies.

Freshwater Ecology, Second Edition, is a broad, up-to-date treatment of everything from the basic chemical and physical properties of water to advanced unifying concepts of the community ecology and ecosystem relationships as found in continental waters.With 40% new and expanded coverage, this text covers applied and basic aspects of limnology, now with more emphasis on wetlands and reservoirs than in the previous edition. It features 80 new and updated figures, including a section of color plates, and 500 new and updated references. The authors take a synthetic approach to ecological problems, teaching students how to handle the challenges faced by contemporary aquatic scientists.This text is designed for undergraduate students taking courses in Freshwater Ecology and Limnology; and introductory graduate students taking courses in Freshwater Ecology and Limnology. - Expanded revision of Dodds' successful text. - New boxed sections provide more advanced material within the introductory, modular format of the first edition. - Basic scientific concepts and environmental applications featured throughout. - Added coverage of climate change, ecosystem function, hypertrophic habitats and secondary production. - Expanded coverage of physical limnology, groundwater and wetland habitats. - Expanded coverage of the toxic effects of pharmaceuticals and endocrine disrupters as freshwater pollutants - More on aquatic invertebrates, with more images and pictures of a broader range of organisms - Expanded coverage of the functional roles of filterer feeding, scraping, and shredding organisms, and a new section on omnivores. - Expanded appendix on standard statistical techniques. - Supporting website with figures and tables - http://www.elsevierdirect.com/companion.jsp?ISBN=9780123747242
