The cost of ever more freguent floods, landslides and erosion on coastal and fluvial structures is considerable. Through more detailed consideration of the risks and their acceptability, the engineering community could make a 5% saving in the whole-life costs of coastal and fluvial engineering projects, amounting to 250 million annually in the UK alone.This book sets out to provide clear guidance on the process of setting acceptable risk levels. It illustrates the importance of involving all stakeholders in the setting of acceptable risk levels and throughout the deisgn process.
"Over 200 billion worth of assets are at risk around British rivers and coasts and those risks are likely to increase over the next 100 years due to changes in climate and in society." Sir David King, Government Chief Scientific Adviser This book presents a comprehensive insight into the flooding system, spanning multiple disciplines across different sectors of the flood and flood management professions. It forecasts the manner in which flooding and coastal erosion risks may increase during the 21st century due to climate change.
"This interim guide to quantitative risk assessment for UK reservoirs provides a tool for the management of reservoir safety by experienced dam professionals. It comprises a screening level assessment of the risk of failure of a dam, i.e. the uncontrolled sudden large release of water from the reservoir it retains." "The guide is in the form of a Microsoft Excel workbook with proforma calculations, and accompanying text. It is intended to form part of either a periodic safety review or a portfolio risk assessment, where application of this guide identifies potential concerns a more detailed assessment is likely to be appropriate."--Résumé de l'éditeur.
Existing coastal management and defense approaches are not well suited to meet the challenges of climate change and related uncertanities. Professionals in this field need a more dynamic, systematic and multidisciplinary approach. Written by an international group of experts, Coastal Risk Management in a Changing Climate provides innovative, multidisciplinary best practices for mitigating the effects of climate change on coastal structures. Based on the Theseus program, the book includes eight study sites across Europe, with specific attention to the most vulnerable coastal environments such as deltas, estuaries and wetlands, where many large cities and industrial areas are located. - Integrated risk assessment tools for considering the effects of climate change and related uncertainties - Presents latest insights on coastal engineering defenses - Provides integrated guidelines for setting up optimal mitigation measures - Provides directly applicable tools for the design of mitigation measures - Highlights socio-economic perspectives in coastal mitigation
This informative manual has been designed to provide guidance on the principal issues surrounding the use of timber in coastal and river engineering. For centuries timber has traditionally been used for the construction of a wide range of coastal and river structures including: groynes, jetties, lock gates, navigation aids and riverbank protection. It is an attractive choice of construction material because it is renewable, is easy to use, repair and recycle, has a high strength/weight ratio and is visually appealing.
River restoration projects are designed to recreate functional characteristics within a context of physical stability. They tend to focus on the development and application of geomorphic principles for river restoration design. Due to different models obtaining different results on the same problem, incomplete or absent data, and climatic/social/cultural changes, the designers and managers of such projects frequently face high levels of uncertainty. This book will provide a systematic overview of the issues involved in minimizing and coping with uncertainty in river restoration projects. A series of thematic sections will be used to define the various sources of uncertainty in restoration projects and how these show at different points in the life cycle (design, construction and post-construction phases) of restoration projects. The structure of the book will offer a rational theoretical analysis of the problem while providing practical guidance in managing the different sources of uncertainty. A wide range of case studies will be included from Europe, North America and Australasia
Hurricane- and coastal-storm-related losses have increased substantially during the past century, largely due to increases in population and development in the most susceptible coastal areas. Climate change poses additional threats to coastal communities from sea level rise and possible increases in strength of the largest hurricanes. Several large cities in the United States have extensive assets at risk to coastal storms, along with countless smaller cities and developed areas. The devastation from Superstorm Sandy has heightened the nation's awareness of these vulnerabilities. What can we do to better prepare for and respond to the increasing risks of loss? Reducing Coastal Risk on the East and Gulf Coasts reviews the coastal risk-reduction strategies and levels of protection that have been used along the United States East and Gulf Coasts to reduce the impacts of coastal flooding associated with storm surges. This report evaluates their effectiveness in terms of economic return, protection of life safety, and minimization of environmental effects. According to this report, the vast majority of the funding for coastal risk-related issues is provided only after a disaster occurs. This report calls for the development of a national vision for coastal risk management that includes a long-term view, regional solutions, and recognition of the full array of economic, social, environmental, and life-safety benefits that come from risk reduction efforts. To support this vision, Reducing Coastal Risk states that a national coastal risk assessment is needed to identify those areas with the greatest risks that are high priorities for risk reduction efforts. The report discusses the implications of expanding the extent and levels of coastal storm surge protection in terms of operation and maintenance costs and the availability of resources. Reducing Coastal Risk recommends that benefit-cost analysis, constrained by acceptable risk criteria and other important environmental and social factors, be used as a framework for evaluating national investments in coastal risk reduction. The recommendations of this report will assist engineers, planners and policy makers at national, regional, state, and local levels to move from a nation that is primarily reactive to coastal disasters to one that invests wisely in coastal risk reduction and builds resilience among coastal communities.
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.
This comprehensive and up-to-date volume contains 367 papers presented at the 29th International Conference on Coastal Engineering, held in Lisbon, Portugal, 19-24 September 2004. It is divided into five parts: waves; long waves, nearshore currents, and swash; sediment transport and morphology; coastal management, beach nourishment, and dredging; coastal structures. The contributions cover a broad range of topics including theory, numerical and physical modeling, field measurements, case studies, design, and management. Coastal Engineering 2004 provides engineers, scientists, and planners state-of-the-art information on coastal engineering and coastal processes.The proceedings have been selected for coverage in:
Proceedings of the 2011 Conference on Coastal Engineering Practice, held in San Diego, California, August 21-24, 2011. Sponsored by the Coasts, Oceans, Ports, and Rivers Institute of ASCE. This collection contains 90 papers that focus on developing solutions to coastal engineering problems and ensuring sustainable coastal development. Papers reflect an emphasis on practical experience and actual projects rather than specific technical and scientific aspects of coastal engineering. Topics include: case histories of coastal projects; sustainable coastal development; erosion and shoreline protection; coastal environment, water quality, and wetlands restoration; coastal hazards and risk management; coastal sediment processes; ports, harbors, and marine transportation; and local, state, and federal involvement in planning, design, and construction of coastal projects. These papers enhance the exchange of real-world experience and thus will be of interest to practicing coastal engineers.
