Flood Catastrophe Modeling

Mastering the volatility of global flood risk

Outdated, low-resolution flood maps obscure true exposure and threaten portfolio solvency. Cotality delivers high-fidelity, probabilistic flood modeling that transforms uncertainty into a competitive advantage for insurers, reinsurers, and ILS investors.

Precision analytics

Granular modeling for high-stakes decisioning

Move beyond traditional flood zones. Our platform utilizes advanced hydraulic modeling and high-resolution digital elevation models to provide a 360-degree view of risk. From pluvial flash flooding to complex storm surges, we capture the physical realities of risk with scientific precision and granularity.
