Toetsnorm als de schade bij overstromen kan variëren

De vraag is gerezen of de toetsnorm voor waterveiligheid goed wordt bepaald als er geen rekening wordt gehouden met de mogelijkheid dat de schade bij overstromen afhangt van de waterhoogte bij overstromen of de kans op die overstroming. Het achterliggend idee is: Hoe extremer de gebeurtenis, des te groter is de overstroming en de daaruit...

Een algemeen toepasbare definitie voor de toetsnorm voor waterveiligheid

In CPB memorandum 195 is een voorstel gedaan voor een toetsnorm op basis van kostenbatenanalyse om na te gaan of dijkringen voldoende veilig zijn voor overstromingen. Naar aanleiding van ervaringen in de praktijk bevat dit memorandum het voorstel om de berekening van de toetsnorm voortaan uitsluitend te baseren op de eerstvolgende investering ...

New safety standards for coastal flood defences in the Netherlands

The Dutch government is in the process of revising its flood safety policy. The current safety standards for flood defences in the Netherlands are largely based on the outcomes of cost-benefit analyses. Loss of life has not been considered separately in the choice for current standards. This article presents the results of a research project...

Developments in levee reliability and flood risk analysis in the Netherlands

This paper presents and overview of advances in flood risk and levee reliability analysis in the Netherlands. It is described how new safety standards – in the form of a target failure probability – have been derived on the basis of nationwide flood risk assessments which taken into account both economic risk and risk to life. The process for...

Towards Improved Flood Defences: Five Years of All-Risk Research into the New Safety Standards

Without our dikes and dunes, 60% of the Netherlands would flood on a regular basis. This area is home to 9 million people. The latest<br/>report of the Intergovernmental Panel on Climate Change (IPCC, February 2022) underlines the importance of reinforcing water safety. Sea levels are rising and extreme weather is becoming increasingly common....
