Global Flood Exposure & Risk Model

Risklayer supports Fathom, one of the leading providers of flood risk models, in building the 30m Fathom Global Flood Model.

For this purpose, we develop the exposure and vulnerability components of the GFM, and provide empirical loss metrics for calibration and benchmark model results for validation

Exposure

• Global Admin2 level replacement values, downscaled to the 30m model resolution
• Residential, Commercial and Industrial Lines of Business

Use Case:

• Built-in Portfolio disaggregation
• Generic portfolio for model validation

Vulnerability

• Line of Business and Risk Type specific vulnerability functions
• Pluvial, fluvial, and coastal
• Regional functions
• Buildings, Contents and in parts Business Interruption

Use Case: GFM Vulnerability Component

Validation

• Empirical Flood AAL and PML metrics from our CATDAT event loss database
• For selected countries: Empirical AEPs and OEPs
