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

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.

Paul Hudson is Associate Professor of Physical Geography at Leiden University, The Netherlands. After completing a PhD in fluvial geomorphology at Louisiana State University, Hudson was Assistant and then Associate Professor at the University of Texas at Austin for fourteen years, until his move to The Netherlands. His current projects examine river management and geomorphology along rivers in Northern Europe, Texas, and the Lower Mississippi River in Louisiana.

Hans Middelkoop is full professor of Physical Geography at Utrecht University. After completing his PhD on embanked floodplains at Utrecht University, Middelkoop was employed at the Netherlands' national Institute for Inland Water Management and Wastewater Treatment (RWS-RIZA). Since 1999 Middelkoop has been appointed at Utrecht University. His research group examines the morphodynamics of rivers, floodplains and deltas across a range of scales, and how these change in response to internal fluvial dynamics, climate, land use changes and human impact. Middelkoop has been active in numerous research projects related to river restoration.
