Download or read book Dam and Levee Safety and Community Resilience written by National Research Council and published by National Academies Press. This book was released on 2012-09-11 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although advances in engineering can reduce the risk of dam and levee failure, some failures will still occur. Such events cause impacts on social and physical infrastructure that extend far beyond the flood zone. Broadening dam and levee safety programs to consider community- and regional-level priorities in decision making can help reduce the risk of, and increase community resilience to, potential dam and levee failures. Collaboration between dam and levee safety professionals at all levels, persons and property owners at direct risk, members of the wider economy, and the social and environmental networks in a community would allow all stakeholders to understand risks, shared needs, and opportunities, and make more informed decisions related to dam and levee infrastructure and community resilience. Dam and Levee Safety and Community Resilience: A Vision for Future Practice explains that fundamental shifts in safety culture will be necessary to integrate the concepts of resilience into dam and levee safety programs.

Download or read book Erosion in Geomechanics Applied to Dams and Levees written by Stephane Bonelli and published by John Wiley & Sons. This book was released on 2013-04-08 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Erosion is the most common cause of failures at earth-dams, dikes and levees, whether through overtopping and overflowing, or internal erosion and piping. This book is dedicated to the phenomenon of internal erosion and piping. It is not intended to be exhaustive on the subject, but brings together some of the latest international research and advances. Emphasis is placed on physical processes, how they can be studied in the laboratory, and how test results can be applied to levees and dams. The results from several research projects in Australia, France, the Netherlands and the United States are covered by the authors. Our aim has been to share our most recent findings with students, researchers and practitioners. Understanding the failure of an earth-dam or a levee by erosion in a unified framework, whether internal erosion or surface erosion, requires continuous research in this field. We hope that the reader will gain knowledge from this book that leads to further progress in the challenging field of the safety of levees and dams. Contents 1.

This book was released on 2013-07-18 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Emergency Management Agency's (FEMA) Federal Insurance and Mitigation Administration (FIMA) manages the National Flood Insurance Program (NFIP), which is a cornerstone in the U.S. strategy to assist communities to prepare for, mitigate against, and recover from flood disasters. The NFIP was established by Congress with passage of the National Flood Insurance Act in 1968, to help reduce future flood damages through NFIP community floodplain regulation that would control development in flood hazard areas, provide insurance for a premium to property owners, and reduce federal expenditures for disaster assistance. The flood insurance is available only to owners of insurable property located in communities that participate in the NFIP. Currently, the program has 5,555,915 million policies in 21,881 communities3 across the United States. The NFIP defines the one percent annual chance flood (100-year or base flood) floodplain as a Special Flood Hazard Area (SFHA). The SFHA is delineated on FEMA's Flood Insurance Rate Maps (FIRM's) using topographic, meteorologic, hydrologic, and hydraulic information. Property owners with a federally back mortgage within the SFHAs are required to purchase and retain flood insurance, called the mandatory flood insurance purchase requirement (MPR). Levees and floodwalls, hereafter referred to as levees, have been part of flood management in the United States since the late 1700's because they are relatively easy to build and a reasonable infrastructure investment. A levee is a man-made structure, usually an earthen embankment, designed and constructed in accordance with sound engineering practices to contain, control, or divert the flow of water so as to provide protection from temporary flooding. A levee system is a flood protection system which consists of a levee, or levees, and associated structures, such as closure and drainage devices, which are constructed and operated in accordance with sound engineering practices. Recognizing the need for improving the NFIP's treatment of levees, FEMA officials approached the National Research Council's (NRC) Water Science and Technology Board (WSTB) and requested this study. The NRC responded by forming the ad hoc Committee on Levee and the National Flood Insurance Program: Improving Policies and Practices, charged to examine current FEMA treatment of levees within the NFIP and provide advice on how those levee-elated policies and activities could be improved. The study addressed four broad areas, risk analysis, flood insurance, risk reduction, and risk communication, regarding how levees are considered in the NFIP. Specific issues within these areas include current risk analysis and mapping procedures behind accredited and non-accredited levees, flood insurance pricing and the mandatory flood insurance purchase requirement, mitigation options to reduce risk for communities with levees, flood risk communication efforts, and the concept of shared responsibility. The principal conclusions and recommendations are highlighted in this report.
Download or read book Dam Politics written by William Robert Lowry and published by Georgetown University Press. This book was released on 2003 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The politics of building dams and levees and other structures are just part of the policies determining how American rivers are managed or mismanaged. America's well-being depends upon the health of those rivers and important decisions go beyond just dam-building or dam removal. American rivers are suffering from poor water quality, altered flows, and diminished natural habitat. Current efforts by policymakers to change the ways American rivers are managed range from the removal of dams to the simulation of seasonal flows to the restoration of habitat, all with varying degrees of success. Efforts to restore American rivers are clearly delineated by William Lowry in Dam Politics as he looks at how public policy and rivers interact, examines the physical differences in rivers that affect policies, and analyzes the political differences among the groups that use them. He argues that we are indeed moving into an era of restoration (defined in part as removing dams but also as restoring the water quality, seasonal flows, and natural habitat that existed before structural changes to the rivers), and seeks to understand the political circumstances that affect the degree of restoration. Lowry presents case studies of eight river restoration efforts, including dam removals on the Neuse and Kennebec rivers, simulation of seasonal flows on the Colorado river, and the failed attempt to restore salmon runs on the Snake river. He develops a typology of four different kinds of possible change--dependent on the parties involved and the physical complexity of the river--and then examines the cases using natural historical material along with dozens of interviews with key policymakers. Policy approaches such as conjunctive water management, adaptive management, alternative licensing processes, and water marketing are presented as possible ways of using our rivers more wisely. Dam Politics provides a useful and systematic account of how American waterways are managed and how current policies are changing. American rivers are literally the lifeblood of our nation. Lowry has written a lively and accessible book that makes it clear as a mountain stream that it matters deeply how those rivers are managed.

Book excerpt: "Nothing is more important to life than water, and no one knows water better than Sandra Postel. Replenish is a wise, sobering, but ultimately hopeful book." --Elizabeth Kolbert "Remarkable." --New York Times Book Review "Clear-eyed treatise...Postel makes her case eloquently." --Booklist, starred review "An informative, purposeful argument." --Kirkus We spend billions of dollars on irrigation, dams, sanitation plants, and other feats of engineering to control water for our own prosperity. What if the answer was not control, but replenishment? Sandra Postel takes readers around the world to explore water projects that work with, rather than against, nature's rhythms. Forest rehabilitation is safeguarding drinking water, farmers are planting cover crops to reduce polluted runoff, and "sponge cities" are capturing rainwater to curb urban flooding. Postel argues that efforts like these will be essential as we adjust to a hotter, wilder climate. Will we continue to fight the water cycle, endangering ourselves and the planet, or recognize our place in it and take advantage of the inherent services nature offers?
Download or read book Design and Construction of Levees written by United States. Army. Corps of Engineers and published by . This book was released on 2004-10 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to present basic principles used in the design and construction of earth levees. The term levee as used herein is defined as an embankment whose primary purpose is to furnish flood protection from seasonal high water and which is therefore subject to water loading for periods of only a few days or weeks a year. Embankments that are subject to water loading for prolonged periods (longer than normal flood protection requirements) or permanently should be designed in accordance with earth dam criteria rather than the levee criteria given herein. Even though levees are similar to small earth dams they differ from earth dams in the following important respects: (a) a levee embankment may become saturated for only a short period of time beyond the limit of capillary saturation, (b) levee alignment is dictated primarily by flood protection requirements, which often results in construction on poor foundations, and (c) borrow is generally obtained from shallow pits or from channels excavated adjacent to the levee, which produce fill material that is often heterogeneous and far from ideal. Selection of the levee section is often based on the properties of the poorest material that must be used.
