This book was released on 1999-04-28 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sacramento, California, has grown literally at the edge of the Sacramento and American Rivers and for 150 years has struggled to protect itself from periodic floods by employing structural and land management measures. Much of the population lives behind levees, and most of the city's downtown business and government area is vulnerable to flooding. A major flood in 1986 served as impetus for efforts by federal, state, and local entities to identify an acceptable and feasible set of measures to increase Sacramento's level of safety from American River floods. Numerous options were identified in 1991 by the U.S. Army Corps of Engineers (USACE) in a report known as the American River Watershed Investigation. Due to the controversial nature of many of the alternatives identified in that report, study participants were not able to reach consensus on any of the flood control options. In response, the Congress directed the USACE to reevaluate available flood control options and, at the same time, asked the USACE to engage the National Research Council (NRC) as an independent advisor on these difficult studies. In 1995 NRC's Committee on Flood Control Alternatives in the American River Basin issued Flood Risk Management and the American River Basin: An Evaluation. This report outlined an approach for improving the selection of a flood risk reduction strategy from the many available.

This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floods constitute a persistent and serious problem throughout the United States and many other parts of the world. They are responsible for losses amounting to billions of dollars and scores of deaths annually. Virtually all parts of the nation--coastal, moun tainous and rural--are affected by them. Two aspects of the problem of flooding that have long been topics of scientific inquiry are flood frequency and risk analyses. Many new, even improved, tech niques have recently been developed for performing these analyses. Nevertheless, actual experience points out that the frequency of say a IOO-year flood, in lieu of being encountered on the average once in one hundred years, may be as little as once in 25 years. It is therefore appropriate to pause and ask where we are, where we are going and where we ought to be going with regard to the technology of flood frequency and risk analyses. One way to address these ques tions is to provide a forum where people from all quarters of the world can assemble, discuss and share their experience and expertise pertaining to flood frequency and risk analyses. This is what con stituted the motivation for organizing the International Symposium on Flood Frequency and Risk Analyses held May 14-17, 1986, at Louisiana State Universj. ty, Baton Rouge, Louisiana.

Download or read book Risk Analysis and Uncertainty in Flood Damage Reduction Studies written by National Research Council and published by National Academies Press. This book was released on 2000-10-20 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing flood damage is a complex task that requires multidisciplinary understanding of the earth sciences and civil engineering. In addressing this task the U.S. Army Corps of Engineers employs its expertise in hydrology, hydraulics, and geotechnical and structural engineering. Dams, levees, and other river-training works must be sized to local conditions; geotechnical theories and applications help ensure that structures will safely withstand potential hydraulic and seismic forces; and economic considerations must be balanced to ensure that reductions in flood damages are proportionate with project costs and associated impacts on social, economic, and environmental values. A new National Research Council report, Risk Analysis and Uncertainty in Flood Damage Reduction Studies, reviews the Corps of Engineers' risk-based techniques in its flood damage reduction studies and makes recommendations for improving these techniques. Areas in which the Corps has made good progress are noted, and several steps that could improve the Corps' risk-based techniques in engineering and economics applications for flood damage reduction are identified. The report also includes recommendations for improving the federal levee certification program, for broadening the scope of flood damage reduction planning, and for improving communication of risk-based concepts.

Download or read book Analyses of Extreme Flood in the Holocene to Improve Flood Frequency Estimation written by Ray Lombardi and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme floods observations are underrepresented in short stream gauge records. Consequently, instrumented records are limited in providing meaningful insight into their mechanistic drivers and frequency. Increasingly, multi-millennia-long paleoflood records (geomorphic and botanical evidence of floods) are used to enhance flood analyses to improve flood frequency estimation. My dissertation includes four studies under two overarching questions: (1) How does climate variability influence flood magnitude and frequency? (2) What are the best practices for interpreting and implementing paleofloods from alluvial systems in complex geomorphic environments for flood frequency analyses? Using regionally synthesized paleoflood records, I was able to identify observation of extreme flood processes under multiple climate conditions not apparent in the instrumented record alone. In Chapter 2, I compiled paleoflood records from Europe and North America over the last 2,000 years to examine flood response to large-scale climate periods. The regionally consistent timing of the most extreme floods from 1000-1300 CE suggests warmer temperatures augmenting precipitation can also augment flood magnitude. In Chapter 5, I compiled paleoflood records in the lower Tennessee River to evaluate Holocene flood variability. Periods of extreme flooding all occurred during large-scale abrupt climate transitions dominated by summer precipitation and following extended periods of drought. Addressing question two, I used reconstructed paleofloods from natural levees and dated surfaces of stable fluvial landforms to test strategies to implement paleoflood data from alluvial rivers in flood frequency analyses. Chapter 3 emphasized the importance of addressing floodplain aggradation and localized sediment variability to build robust paleoflood chronologies. Chapter 4 demonstrates the challenges in interpreting perception thresholds and non-exceedance bounds in complex alluvial environments using traditional approaches and tested more suitable alternatives for the environment. These advancements can improve the utility of paleoflood information in currently understudied river basins, particularly in regulated or ungauged rivers in humid climates. The work in this dissertation strengthens the evidence that extreme floods will become more frequent in response to warm temperatures. Specific drivers described in this body of work suggest that the rate of climate change and increased intensities in drought and heavy precipitation may augment flood hazards.

This book was released on 2010 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An underlying assumption of traditional hydrologic frequency analysis is that climate, and hence the frequency of hydrologic events, is stationary, or unchanging over time. A stationary series is relatively easy to forecast: one simply predicts that statistical properties will be the same in the future as they have been in the past. Anthropogenic climate change and better understanding of decadal and multi-decadal climate variability present a challenge to the validity of this assumption. The workshop ... was organized to present and discuss possible operational alternatives to the assumption of stationarity in hydrologic frequency analysis."--Abstract.
