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.




Floodplain Management Plan


Book Description

"The Murrumbidgee River Hay to Maude Floodplain Management Plan (the FMP) has been prepared to provide strategic guidance to the NSW Government and landholders who are involved in the management of floodwaters on the Murrumbidgee River (Hay to Maude) floodplain. The vision for the FMP is: an environment where flood risk to occupiers and users of the floodplain is minimised and flood dependent ecosystems within the floodplain and on the downstream Lowbidgee floodplain are sustained by access to floodwaters"--Page 1.







Flooding and Management of Large Fluvial Lowlands


Book Description

Examines interrelations between flood management, flooding, and environmental change, for advanced students, researchers, and practitioners.




Alluvial Fan Flooding


Book Description

Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.










Restoring Floodplains in Europe


Book Description

This book addresses the complex institutional dimensions to restoring floodplains. Despite the recent surge of interest in restoring floodplains among policy and research circles, as well as in the public domain, very few schemes for restoring functional floodplains have been put into practice in Europe to date. The book explores the reasons behind this discrepancy between interest and applications with an original, comparative analysis of the institutional drivers and constraints of floodplain restoration in Europe. It explains why so few projects have been successfully implemented, how recent policy shifts are creating new opportunities for floodplain restoration and what lessons for policy development and project management can be drawn from in-depth analysis of past and present schemes. At a time of rapidly growing interest in restoring floodplains as an important component of efforts to improve flood protection, enhance riparian habitats, strengthen catchment management, raise water quality and pursue integrated rural development, the book critically appraises the relationship between macro-level policy development and enforcement and micro-level project design and implementation. The book begins with two chapters setting out the case for floodplain restoration and assessing the relevant drivers and constraints of EU policy. The next three chapters analyse the policy contexts of floodplain restoration in France, Germany and Britain, addressing the principal drivers and constraints in the fields of water management, flood protection, nature conservation, spatial planning and agriculture. This is followed by six case studies of schemes to restore floodplains, divided between early schemes of the mid-1990s (Rheinvorland-Sud on the Upper Rhine, Bourret on the Garonne and the Long Eau project in England) and ongoing schemes of today (Lenzen on the Elbe, La Basse on the Seine and the Parrett Catchment Project). The book concludes by drawing lessons from the principal findings and providing recommendations for ways of developing policy and designing projects for restoring floodplains in the future.
