SFINCS
SFINCS is a new fast numerical model to simulate 2D compound flooding dynamically for large scale coastal systems, within a fraction of the time required by our 1D2D models.

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 (Super-Fast INundation of CoastS) 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.
The model is an additional flavor for fast quickscan computations of compound flooding within the modeling suite of Deltares. The new model can also be deployed to provide large-scale flood estimates in the Delft-FEWS early warning system, quickly test flood mitigation and adaptation measures or to calculate flood risk and impact through providing input to Delft-FIAT.
The tool has been successfully applied in various studies across the world: Australia, Bangladesh, Liberia, Marshall Islands, Mozambique, Caribbean islands, Small Island Developing States and the United States to name a few.
