New AI Research Aims to Predict Coastal Flooding
A new open-access study investigates the use of artificial intelligence to more reliably predict coastal wave overtopping, a key process in assessing flood risk for low-lying areas. The research identifies promising AI methods for improving both the accuracy of predictions and the understanding of physical processes, which is critical for climate adaptation and infrastructure planning in coastal regions like the Netherlands.
- Rijkswaterstaat, the Dutch water management authority, is collaborating with research institute Deltares and the meteorological institute KNMI on a four-year program to develop new AI-driven models for predicting water levels in coastal areas, rivers, and lakes. These machine learning models can calculate scenarios in seconds rather than the hours required by traditional numerical models, allowing for quicker action to mitigate damage. - The Netherlands is a key participant in the European Union's Destination Earth (DestinE) initiative, which is creating a "digital twin" of the Earth. Deltares is integrating data from this digital twin into its Flood Early Warning Systems (FEWS), which are used in over fifty countries to better estimate the impact of floods. - A joint project called JCAR is underway between the Netherlands and Germany to develop a cross-border flood early warning system for shared river basins. The Dutch research institute Deltares is collaborating with the German climate-tech company FloodWaive on a comprehensive concept study for this initiative. - Digital twin technology is being implemented across Dutch water management infrastructure; for instance, the Waterschapsbedrijf Limburg regional water authority is creating a virtual copy of its 17 wastewater treatment plants and nearly 150 sewage pumping stations to enable scenario planning and analysis in a risk-free environment. This is part of a broader trend that includes developing 3D digital twins for high-resolution flood modeling and risk visualization. - In addition to high-tech solutions, the Netherlands continues to invest in nature-based coastal defenses like the Zandmotor ("Sand Motor"). This massive sand replenishment project uses natural currents and wind to distribute sand along the coast, building up beaches and dunes as a defense against sea-level rise and storm surges. - The Association of Netherlands Municipalities (VNG) supports local governments in developing climate resilience through practical solutions like capturing excess rainwater to prevent flooding. VNG International works to enhance spatial planning and integrate climate adaptation into municipal projects to build resilience against disasters. - A spin-off from the University of Twente, Fast Hazard, has launched a platform called FastFlood Global that can simulate detailed floods anywhere on Earth in seconds. This technology, which has already been tested on events like the 2021 Valkenburg floods, allows planners and emergency services to instantly test various flood scenarios. - The Dutch government's long-term strategy is guided by the Delta Programme, which was initiated after the 1953 flood disaster and focuses on flood safety, freshwater supply, and climate-resilient spatial planning. This proactive approach has shifted from disaster remediation to pre-empting future events through continuous innovation and infrastructure improvements like the Afsluitdijk reconstruction.
