Innovative Flood Protection Measures in The Netherlands

Learn about the flood protection strategies in the Netherlands, a country with 26% below sea level. With threats from the North Sea and main rivers like Rhine and Meuse, innovative solutions like levees, dams, and barriers are in place. Discover the lessons learned from historical disasters and the proactive approach of the Dutch government and water authorities. Explore the evolution of flood protection plans, from the Protection of Ysselmeer to the New Delta Commission, to address challenges like rising sea levels, soil subsidence, and density of urban population. Join the conversation on global flood protection efforts and the importance of fostering creativity and collaboration in facing climate-related risks.

  1. Flood protection in The Netherlandsdr. Sybe Schaap, President Association of Water Autorities Chairman Water Board Groot Salland

  2. Netherlands:best protected delta region word wide

  3. The Netherlands 26% below sea level When no dikes/dunes:66% frequently under water

  4. The Netherlands26% below sea levelWhen no dikes/dunes:66% frequently under water

  5. The Netherlands26% below sea levelWhen no dikes/dunes:66% frequently under water

  6. Threats- North Sea- Inner Lake: Ysselmeer- Main Rivers: Rhine, Meuse

  7. Risks- level country: to 6 m below sea level- dense population: 12 mln below sea level - high level of investments- insurance/evacuation impossibleSolution: high level of protection = prevention against floods

  8. Protection- rings of levees - dams: fixed or flexible

  9. Level of protection- 1/1.250 - 1/10.000- level probably insufficient

  10. Organization of water management- Central government - legal system - strategic policy - main system- Regional Water Authorities

  11. Water Authorities in The Netherlands: 26

  12. Lessons from history- often to late: disasters- clever response = reactive attitude- 1953: flood from North Sea- 1995: flood from River Rhine- challenges for response

  13. Response- Protection Ysselmeer (1932) - Delta plan North Sea (1959)- Delta plan main rivers(1995)- Room for Rivers (2004)- New Delta Commission (2007)

  14. Protection Ysselmeer

  24. Flood defence system Kampen (red line)

  25. Room for Main Rivers

  26. Bypass Kampen

  27. Delta Commission- Pro active attitude- Vision until 2200- Extraction of new measures - coast defense - threat from rivers - soil subsidence

  28. Threat word wide- climate?- sea level- soil subsidence in urbanized areas (delta’s/coasts)- density of population- New Orleans: wake up call

  29. Protectioncorporation of: - public authorities - private partnersChallenge: creativity
