Dutch AI Startup Develops Real-Time Flood Prediction Model for Coastal Cities

AI Meets Water Management in the Low Countries

The Netherlands, a nation where nearly one-third of the land lies below sea level, has turned to artificial intelligence to strengthen its world-renowned flood defense systems. A consortium led by Delft University of Technology and the Deltares research institute has developed a real-time flood prediction model that can forecast storm surge impacts up to 72 hours in advance with unprecedented accuracy.

The model, dubbed “WaterWise NL,” ingests data from over 5,000 sensors spread across the Dutch coastline, rivers, and polder drainage systems. It combines this with meteorological forecasts from the Royal Netherlands Meteorological Institute (KNMI) and satellite imagery to produce hyperlocal flood risk maps updated every 15 minutes.

From Reactive to Predictive

Traditional Dutch water management relies heavily on physical infrastructure: the iconic dikes, storm surge barriers like the Maeslantkering, and pumping stations that move water out of low-lying polders. WaterWise NL adds a predictive layer on top of this physical backbone.

“What makes this different is the speed and granularity,” explains Dr. Marleen van Rijswick, professor of water law at Utrecht University. “We can now model individual neighbourhoods in Rotterdam or The Hague and know, with 94% confidence, whether a particular street will flood during a storm.”

The system uses a transformer-based neural network architecture, similar to the technology behind large language models, but trained on hydrological data rather than text. Early trials during the 2025-2026 winter storm season correctly predicted 17 out of 18 flood events across the Rhine-Meuse-Scheldt delta.

International Interest

Countries facing similar challenges have taken notice. Vietnam, Bangladesh, and Indonesia — all nations with extensive low-lying coastal areas — have sent delegations to Delft to study the system. The World Bank has earmarked €40 million for a pilot programme to adapt WaterWise NL for Southeast Asian monsoon conditions.

The Dutch government has committed €85 million to expand the sensor network to cover the entire Wadden Sea coast by 2028. “Water safety is in our DNA,” said Minister of Infrastructure and Water Management Barry Madlener. “AI gives us a new set of tools to protect what generations of Dutch engineers have built.”
