Foundation 3Di takes water management in the 21st century to a higher plane

Published: 27 November 2014

Here in the Netherlands, the heavy rainfall last summer gave us a taste of what climate change can bring. Despite our strong reputation for water management, the downpours - more than 100 mm of rain in just a few hours - still took us by surprise.

100 times more detailed and 100 times faster than existing models

So there is considerable interest in 3Di, a new simulation model that calculates the impact of intense rainfall very precisely. 3Di is 100 times more detailed and 100 times faster than the existing models. The precise calculations not only make it clear where the vulnerable areas are, but also how they can be protected in a cost-effective way. This could save tens of millions by tailoring upgrade measures.

International interest

The new model was developed by Deltares, Delft University of Technology and Nelen & Schuurmans. It is now being used by water authorities and municipal authorities, including Amsterdam, Rotterdam and The Hague. But there is also international interest in the new 3Di model.

Today the 3Di foundation was established

To further the development of 3Di at the national and international levels, the 3Di Foundation (“Stichting 3Di”) was established today. The foundation will collaborate closely with the water authorities to take water management in the 21 st century to a higher plane and to generate international attention for the approach.
