The project

The Dutch Delta Decisions were submitted to the Dutch parliament in 2014. The Delta Plan, Delta Programme and Delta Decisions are a showcase for new thinking in water management. They regulate flood risk management and safety in the Netherlands for the coming decades.

Our role in the Netherlands and the results

Not only did we contribute to the technical studies for these decisions, we were also involved in adaptive delta management. The benefit of this approach is that, if things work out differently than expected (for example if new climate scenarios develop), the plans will not require a complete overhaul; it may be possible to take steps earlier or later than planned.

For the adaptive delta management method, Deltares developed important tools such as delta scenarios, adaptation paths and tipping points.
