SFINCS is Deltares' new open-source, open-access reduced-complexity model designed for super-fast modelling of compound flooding events in a dynamic way!
Deltares is a not-for-profit independent institute for applied research in the field of water, subsurface and infrastructure.
Compound flooding during extreme events can result in tremendous amounts of property damage and loss of life. Early warning systems and multi-hazard risk analysis can reduce these impacts. However, traditional approaches either do not involve relevant physics or are too computationally expensive to do so for large stretches of coastline. The SFINCS model is a new reduced-complexity engine recently developed by Deltares, that is capable of simulating compound flooding including a high computational efficiency balanced with good accuracy.
