Flood Risk Management

Some 60% of the Netherlands is prone to flooding. These areas accommodate nine million people and the bulk of our gross national product is earned here. Consequently, working on flood protection is a continuous necessity in the Netherlands. This is why, in the context of the Delta Programme, the Delta Decision on Flood Risk Management has been prepared in recent years, together with all the stakeholders involved.

New insights, greater safety

The Delta Decision on Flood Risk Management will provide every individual behind the dykes or dunes with the same level of protection: the probability of individual mortality as a result of flooding must not exceed 1:100,000 per annum. Higher protection levels apply in areas where flooding may cause major damage (in terms of large numbers of victims or economic loss). These goals have been translated into new standards for the dykes, dunes, and dams protecting our country against flooding from the sea, the major rivers, and the large lakes. This means that flood risk management is tackled in a more focused and more effective manner, offering more protection for people and the economy. The new flood risk management policy is future-oriented and looks ahead to the situation expected for 2050. The aim is for all the flood defence systems to meet the new standards by then. The flood risk management measures are presented in the Delta Plan on Flood Risk Management.

New standards in the Water Act

The Water Act sets out the standards to be met for dykes and dunes. The amended Water Act came into force on 1 January 2017.

New tools and tasking up to 2050

Setting down the new standards does not mean that our work is done. In order to be able to apply the new standards, the central government is developing an instrument, together with the district water boards, to assess the safety of the dykes, dunes and dams once every 12 years in accordance with the new method. The new assessment method works from coarse to fine: simple wherever it is possible and detailed wherever it is necessary. The dyke and dune managers will commence their assessment in 2017. By 2023, this will yield a national picture of dyke improvement tasking up to 2050. Dyke sections that do not meet the new standards will be tackled before 2050. In most cases, this will involve dyke or dune improvements, or creating more room for rivers. Most of these measures are being carried out under the Delta Plan on Flood Risk Management

Delta Plan on Flood Risk Management

The Delta Plan on Flood Risk Management comprises all the Delta Programme studies, measures, and provisions aimed at protecting the Netherlands against flooding. The plan contains a detailed schedule for the first six years and an outline schedule for the subsequent twelve years. It also looks ahead to 2050. Most of the measures are funded from the Delta Fund. The Delta Plan is a component of the Delta Programme annually presented by the Delta Programme Commissioner.

To view the progress made regarding flood risk management, read the chapter on Flood Risk Management in Delta Programme 2018. The schedule of studies and projects can be found in Part III, Delta Plan on Flood Risk Management.
