  1. Coastal and Floodplain Management: the US and Dutch Experience Paul Bourget USACE USA Jean-Marie Stam Rijkswaterstaat Netherlands

  2. In May 2004, the US Army Corps of Engineers and the Dutch Rijkswaterstaat (of the Ministry of Transport, Public Works and Water management) signed a Memorandum of Agreement to work together on water management. MOA USACE-RWS

  3. Then Katrina came… Louisiana 2005 Zeeland 1953 Louisiana 2005 Zeeland 1953

  4. Drawing a lot of attention to the Netherlands…

  5. …and a lot of Dutch interest in New Orleans…

  6. Louisiana – the Netherlands

  7. “…We need a levee system like the Dutch…” Protecting a world class city like New Orleans with a world class levee system like the Dutch have is what we need to do to protect this national treasure. A Netherlands-type of levee system will protect residents, neighbourhoods, and businesses in New Orleans. That’s what homeland security is about. Broadening Katrina’s Lens , no 4: Katrina’s bigger pictureTuesday, July 10, 2007 Netherlands Levees New Orleans Levees

  8. Scale

  9. USA Contains the whole river basin Varied hazardscape, none is top priority Variations in density so non-structural measures Netherlands The Dutch are at the end of 3 river basins National focus on one hazard High density so protective infrastructure Scale

  10. History

  11. Governance USA • Flood management shared by many organisations • Shared responsability • Cost shared with local sponsors • USA super power • Taxpayers monies • Individual responsibility litigation culture Netherlands • Flood management in one ministry • Centralized governance • National funded flood infrastructure • Nl part of EU • State monies • “polder model” consensus culture

  12. Flood management approaches USA: prevention & preparedness • Structural (shared responsibility) • Non-structural measures (federal responsibility) • More public awareness and involvement • More flexible and robust in large areas with low pop. density and varied hazardscape Netherlands: protection • System of dikes, levees • System for maintenance • Continuous financing • Law defines responsibilities • Small, densly populated, prosperous • 50 years • Last safety assessment:44% complied; 24% did not comply; 32% unclear

  13. Collaborative opportunities Opportunities • Safety and risk • Technological innovations • Operations and maintenance • Basin level strategies • Coastal zone management • Participatory planning

  14. Collaborative opportunities Learning strategy Time Scale Societal develop. Opportunity • Safety and risk • Technological innovations • Operations and maintenance • Basin level strategies • Coastal zone management • Participatory planning

  15. Conclusions • The US and the Netherlands are learning a great deal from each other • Converging historical development of water management • Differences in scale and, governance lead to different flood protection approaches (prevention and preparation vs. protection) • Because of differences many collaborative oportunities with following key learning strategies: • 50 years head start -> Gerschenkron’s law • Larger scale = more research resources • Similar societal development
