Floodplain Management


Book Description

A flooding river is very hard to stop. Many residents of the United States have discovered this the hard way. Right now, over five million Americans hold flood insurance policies from the National Flood Insurance Program, which estimates that flooding causes at least six billion dollars in damages every year. Like rivers after a rainstorm, the financial costs are rising along with the toll on residents. And the worst is probably yet to come. Most scientists believe that global climate change will result in increases in flooding. The authors of this book present a straightforward argument: the time to stop a flooding rivers is before is before it floods. Floodplain Management outlines a new paradigm for flood management, one that emphasizes cost-effective, long-term success by integrating physical, chemical, and biological systems with our societal capabilities. It describes our present flood management practices, which are often based on dam or levee projects that do not incorporate the latest understandings about river processes. And it suggests that a better solution is to work with the natural tendencies of the river: retreat from the floodplain by preventing future development (and sometimes even removing existing structures); accommodate the effects of floodwaters with building practices; and protect assets with nonstructural measures if possible, and with large structural projects only if absolutely necessary.




Geomorphic Approaches to Integrated Floodplain Management of Lowland Fluvial Systems in North America and Europe


Book Description

This volume provides a comprehensive perspective on geomorphic approaches to management of lowland alluvial rivers in North America and Europe. Many lowland rivers have been heavily managed for flood control and navigation for decades or centuries, resulting in engineered channels and embanked floodplains with substantially altered sediment loads and geomorphic processes. Over the past decade, floodplain management of many lowland rivers has taken on new importance because of concerns about the potential for global environmental change to alter floodplain processes, necessitating revised management strategies that minimize flood risk while enhancing environmental attributes of floodplains influenced by local embankments and upstream dams. Recognition of the failure of old perspectives on river management and the need to enhance environmental sustainability has stimulated a new approach to river management. The manner that river restoration and integrated management are implemented, however, requires a case study approach that takes into account the impact of historic human impacts to the system, especially engineering. The river basins examined in this volume provide a representative coverage of the drainage of North America and Europe, taking into account a range of climatic and physiographic provinces. They include the 1) Sacramento (California, USA), 2) San Joaquin (California), 3) Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota, USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA), 7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10) Danube (Romania), and 11) Volga (Russian Federation) Rivers. The case studies covered in these chapters span a range of fluvial modes of adjustment, including sediment, channel, hydrologic regime, floodplains, as well as ecosystem and environmental associations.

Book Description

This volume presents chapters highlighting the methodologies and tools developed to improve flood management and flood risk reduction.







Flood Risk Management


Book Description

Our changing climate and more extreme weather events have dramatically increased the number and severity of floods across the world. Demonstrating the diversity of global flood risk management (FRM), this volume covers a range of topics including planning and policy, risk governance and communication, forecasting and warning, and economics. Through short case studies, the range of international examples from North America, Europe, Asia and Africa provide analysis of FRM efforts, processes and issues from human, governance and policy implementation perspectives. Written by an international set of authors, this collection of chapters and case studies will allow the reader to see how floods and flood risk management is experienced in different regions of the world. The way in which institutions manage flood risk is discussed, introducing the notions of realities and social constructions when it comes to risk management. The book will be of great interest to students and professionals of flood, coastal, river and natural hazard management, as well as risk analysis and insurance, demonstrating multiple academic frameworks of analysis and their utility and drawbacks when applied to real-life FRM contexts.




Flood Risk Science and Management


Book Description

Approaches to avoid loss of life and limit disruption and damage from flooding have changed significantly in recent years. Worldwide, there has been a move from a strategy of flood defence to one of flood risk management. Flood risk management includes flood prevention using hard defences, where appropriate, but also requires that society learns to live with floods and that stakeholders living in flood prone areas develop coping strategies to increase their resilience to flood impacts when these occur. This change in approach represents a paradigm shift which stems from the realisation that continuing to strengthen and extend conventional flood defences is unsustainable economically, environmentally, and in terms of social equity. Flood risk management recognises that a sustainable approach must rest on integrated measures that reduce not only the probability of flooding, but also the consequences. This is essential as increases in the probability of inundation are inevitable in many areas of the world due to climate change, while socio-economic development will lead to spiralling increases in the consequences of flooding unless land use in floodplains is carefully planned. Flood Risk Science and Management provides an extensive and comprehensive synthesis of current research in flood management; providing a multi-disciplinary reference text covering a wide range of flood management topics. Its targeted readership is the international research community (from research students through to senior staff) and flood management professionals, such as engineers, planners, government officials and those with flood management responsibility in the public sector. By using the concept of case study chapters, international coverage is given to the topic, ensuring a world-wide relevance.




Flood Risk Assessment and Management


Book Description

Flood catastrophes which happened world-wide have shown that it is not sufficient to characterize the hazard caused by the natural phenomenon "flood" with the well-known 3M-approach (measuring, mapping and modelling). Due to the recent shift in paradigms from a safety oriented approach to risk based planning it became necessary to consider the harmful impacts of hazards. The planning tasks changed from attempts to minimise hazards towards interventions to reduce exposure or susceptibility and nowadays to enhance the capacities to increase resilience. Scientific interest shifts more and more towards interdisciplinary approaches, which are needed to avoid disaster. This book deals with many aspects of flood risk management in a comprehensive way. As risks depend on hazard and vulnerabilities, not only geophysical tools for flood forecasting and planning are presented, but also socio-economic problems of flood management are discussed. Starting with precipitation and meteorological tools to its forecasting, hydrological models are described in their applications for operational flood forecasts, considering model uncertainties and their interactions with hydraulic and groundwater models. With regard to flood risk planning, regionalization aspects and the options to utilize historic floods are discussed. New hydrological tools for flood risk assessments for dams and reservoirs are presented. Problems and options to quantify socio-economic risks and how to consider them in multi-criteria assessments of flood risk planning are discussed. This book contributes to the contemporary efforts to reduce flood risk at the European scale. Using many real-world examples, it is useful for scientists and practitioners at different levels and with different interests.




A Unified National Program for Floodplain Management


Book Description

Prepared by the Interagency Task Force on Floodplain Management. Includes National Flood Insurance Program.




Mapping the Zone


Book Description

Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps portray the height and extent to which flooding is expected to occur, and they form the basis for setting flood insurance premiums and regulating development in the floodplain. As such, they are an important tool for individuals, businesses, communities, and government agencies to understand and deal with flood hazard and flood risk. Improving map accuracy is therefore not an academic question-better maps help everyone. Making and maintaining an accurate flood map is neither simple nor inexpensive. Even after an investment of more than $1 billion to take flood maps into the digital world, only 21 percent of the population has maps that meet or exceed national flood hazard data quality thresholds. Even when floodplains are mapped with high accuracy, land development and natural changes to the landscape or hydrologic systems create the need for continuous map maintenance and updates. Mapping the Zone examines the factors that affect flood map accuracy, assesses the benefits and costs of more accurate flood maps, and recommends ways to improve flood mapping, communication, and management of flood-related data.
