Based on our market-leading flood hazard model, Brazil FloodCat™ enables detailed analysis of potential losses from flooding.

At a Glance

  • Flood catastrophe model focused on the Santa Catarina region
  • Census tract-level precision
  • Fluvial flooding loss estimation
  • Flowroute-i™ 2D flood model
  • Full probabilistic event catalogue
  • Up-to-date detailed vulnerability data

Brazil FloodCat includes more than 10,000 years of realistic synthetic flooding events, as well as major historic flood events throughout the Santa Catarina region to give accurate catastrophic flood information right down to individual property level.

Property vulnerability is classified according to usage, occupancy, construction type and other factors. So you can fully understand and quantify the impact of a full range of flood loss scenarios.

Working in close collaboration with the insurance industry, Brazil FloodCat has been thoroughly tested and validated against both historic floods and losses. It’s available immediately through Aon Benfield’s powerful, easy-to-use ELEMENTS platform.

Benefits
