Global Flood Map Methodology Documentation
The report outlines the technical process of combining Fathom's Global Flood Map (v3.1) with Public Safety Canada's residential building data and probabilistic vulnerability functions. It describes the use of 'big data' from US FEMA insurance claims to model damage distributions across 10 residential building types. The methodology accounts for flood defenses based on urbanization levels and applies the trapezium rule across eight return periods to estimate economic losses. Results show that Canada's defended AAL is projected to increase from 1,423 million CAD in 2020 to 1,681 million CAD by 2050, while undefended AAL is significantly higher, reaching 5,050 million CAD by 2050.
