Insurers & Investors Need Better Property Flood Data
As climate change accelerates, cities and property owners face increasing uncertainty around flood risk. Extreme rainfall events are becoming more intense and frequent, resulting in incomplete risk assessments, underprepared communities, and missed opportunities to fund and prioritize climate resilience.
At NOAH Intelligence, we know that escalating climate volatility demands better climate resiliency tools. NOAH HydroSim™ Flood Modelling sets the new standard, combining real-world event data with advanced simulation to generate truly actionable flood risk insights. It’s not just about predicting floods – it’s about equipping people, governments, and industries to prevent losses, protect lives, and build smarter for the future.
Traditional Flood Models
Conventional flood risk models often rely on climate projections applied across broad grid cells (often 10–100 km wide), failing to account for the highly localized nature of rainfall and stormwater runoff behavior. These models also tend to overlook the real-world complexities of urban infrastructure – like the drainage capacity and configuration of storm sewers, the elevation of basements, or the way water flows over different elevations in a neighborhood.
Critically, modelling procedure typically uses return period estimates based on historic rainfall intensity and frequency alone. But as climate change impacts grow, extreme events are becoming more common (e.g., what was once a 1-in-100-year storm may now be a 1-in-20-year event) and these projections no longer represent the true, dynamic risk of flooding from extreme rainfall.
What Makes NOAH HydroSim™ Different?
NOAH HydroSim™ Flood Modelling eliminates projection bias by anchoring flood risk in the physical realities of extreme weather. Our system incorporates a curated set of actual historic rainfall events that have occurred within the climate region of a given property – ensuring that NOAH simulations reflect real-world storm behavior, instead of focusing on theoretical trends.
Why This Matters for Cities, Insurers, and Investors
- Unbiased, Property-Level Precision: NOAH HydroSim™ delivers risk profiles with real-world context – ideal for underwriting, investment decisions, and capital planning.
- Better Scorecards, Smarter Decisions: NOAH’s Flood Risk Scorecards are physics-based outputs, enabling a higher standard of risk communication. Real estate owners can finally act on meaningful data – not approximations.
- Unlocking Adaptation Finance: With adaptation funding still chronically underdelivered – particularly for cities – NOAH HydroSim™ provides the technical backbone needed for feasibility studies, pre-investment assessments, and bankable project proposals.
- Future-Ready Infrastructure Planning: As rainfall patterns shift and infrastructure ages, property managers must assess vulnerabilities with the most advanced tools available. NOAH HydroSim™ provides the simulations needed to justify and prioritize upgrades before disaster strikes.
