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.













Subdivision Design and Flood Hazard Areas


Book Description

Sustainability, resilience, and climate change are top of mind for planners and floodplain managers. For subdivision design, those ideas haven't hit home. The results? Catastrophic flood damage in communities across the country. This PAS Report is out to end the cycle of build-damage-rebuild and bring subdivision design into line with the best of floodplain planning. Readers will get the tools they need to save lives, protect property, and lay the foundation for a better future.

Retrofitting for Flood Resilience


Book Description

This book educates and introduce readers to the ways in which we can adapt to the threat of flooding throughout the built and natural environment. It offers advice on how to better understand the nature of flood risk, whilst highlighting the key approaches and principles necessary for developing community and property-level flood resilience. As a comprehensive and practical manual, this book includes richly illustrated diagrams on a variety of concepts and strategies to use when designing for flood resilience. It is vital resource for anyone looking to adapt to the threat of flood risk. Highly practical handbook for architects, students, engineers, urban planners and other built environment professionals Richly illustrated with practical examples and case studies Draws on research with the Cabinet Office, Environment Agency & Local Community as well as input from academic and industry experts, homeowners and residents of communities at risk of flooding.




Evolving Approaches to Understanding Natural Hazards


Book Description

The 21st century presents many challenges to the hazard manager; dynamic climatic conditions combined with population growth, rapid urbanization, and changing socio-economic relationships are reshaping disaster impacts, community responses, and social safety mechanisms. Indeed, human vulnerability is constantly restructured by the ongoing interplay of physical, social, economic, and political forces. At the same time, reducing vulnerability and enhancing community resilience require policies aimed at mitigating the consequences of disasters as they affect different locations and different groups, requiring sound scientifically-based research to further an understanding of the forces at play, and to devise appropriate means to counter them. It is within this context that this book examines evolving approaches to natural hazards. Research into natural hazards has a long tradition beginning with a focus on physical processes and evolving into an interdisciplinary agenda that incorporates interactions between the physical and human environments, embracing initiatives ranging from the physical to the socio-economic and political. It utilises various methodological approaches and technological advances, employing both quantitative and qualitative procedures. The papers included in this book offer insights into the development of applied hazards research, as they build on previous work, evolving technologies, improved understandings of the factors involved, and increased awareness of the needs of those who manage hazards. This volume shows an appreciation for the foundation that has been set, and will inspire future researchers as they look to address these very pressing social issues.







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.
