FloodAdapt
FloodAdapt is an open-source decision-support tool that helps communities understand and plan for future flooding. It combines powerful, physics-based models with an intuitive interface, making advanced flood and impact simulations accessible to a wide range of users. With FloodAdapt, users can define and evaluate "what-if" scenarios – combinations of flood events, future conditions (like sea level rise or population growth), and adaptation strategies. FloodAdapt then rapidly generates flood and impact maps, informative metrics and infographics, and scenario comparisons to guide robust, equitable decision-making.
What can you do with FloodAdapt?
Explore Flood Scenarios
See how coastal storms, heavy rainfall, tropical cyclones, or compound events could affect your community under current or future conditions.

Test Adaptation Strategies
Simulate options like levees, elevated homes, or green infrastructure to see where they work best - and for how long.

Get Actionable Insights
Understand potential impacts on buildings, roads, and neighborhoods. Obtain clear metrics and infographics to inform planning and engage stakeholders.

How does FloodAdapt work?
FloodAdapt puts advanced modeling power in the hands of planners and communities. Under the hood, it uses SFINCS for rapid, physics-based simulation of compound flooding and the Delft-FIAT tool to assess flood damages to buildings, roads, and other critical assets and infrastructure.
When a user sets up a scenario, FloodAdapt automatically updates these models to reflect the selected event, future conditions, and adaptation options - just as an expert modeler would. The tool then runs the simulation and returns detailed flood and impact maps, comparisons, and summaries, all without requiring technical expertise.
Why FloodAdapt?
- Accessible, intuitive interface
- Powerful modeling under the hood - no modeling expertise needed
- Future risk and adaptation strategies exploration
- Support for both event-based and risk-based planning
- Transparent cost-benefit calculations
- 100% Open Source and no license costs
