JBA's Global Flood Models
Understand flood risk, anywhere in the world.
Our Global Flood Models use cutting-edge science to simulate hundreds of thousands of plausible flood events. They capture the full spectrum of scenarios – from frequent to extreme – to reveal how often flooding might occur, how severe it could be, and what the impacts might be.
Why choose our Global Flood Models?
Flood risk is changing – and in many regions, intensifying. Understanding this risk is critical to protecting people, infrastructure and economies. Our Global Flood Models provide the insight needed to plan, finance and act with confidence.
They help governments, organisations and communities make robust, risk-informed decisions across disaster risk finance, adaptation planning and anticipatory action. Quantifying risk, estimating losses and supporting smarter investment.
A powerful complement to our Global Flood Maps, they reveal not just where flooding might occur – but how often, how severe, and what the impacts could be for people, infrastructure and economies.
Global coverage
Assess flood risk consistently across every country and region worldwide.
Full risk spectrum
Understand flood risk across thousands of plausible scenarios — from frequent events to rare extremes.
Future flood risk
Explore how flood risk may evolve over time to support long-term planning and resilience.
How do they work?
Our Global Flood Models use probabilistic modelling — an industry-standard method trusted by the global insurance sector — to estimate flood risk with confidence. This means simulating hundreds of thousands of scientifically plausible flood events across a full range of scenarios
Risk is calculated by bringing together three key components:
- Hazard – Where flooding could occur
- Exposure – What could be affected (people, infrastructure, assets)
- Vulnerability – How much damage those things might sustain.
By combining these with JBA’s Global Flood Event Set — a large library of realistic flood scenarios — the models generate robust, science-based estimates of flood risk across a range of probabilities
How can our Global Flood Models help you?
Our Global Flood Models provide a consistent, forward-looking view of flood impacts – enabling confident financing, planning and preparedness, anywhere in the world.
- Disaster risk financing
Providing scientifically robust risk estimates to support the design of parametric insurance and sovereign risk financing schemes. Helping define triggers, quantify losses and strengthen financial preparedness.
- Adaptation and investment planning
Informing infrastructure design, land use strategies and adaptation decisions. Supporting cost–benefit analysis for engineering and nature-based solutions under future flood scenarios.
- Anticipatory action and preparedness
Helping identify impact thresholds and flood scenarios in advance. Supporting early action protocols, contingency planning and resource prioritisation for humanitarian and government partners.
