Fathom-US

Fathom-UK CAT

A first for accurately quantifying present and future flood losses

Fathom-UK CAT has been built in tandem with Fathom's flood hazard data for the UK.

The probabilistic model uniquely characterises the relationship between flood depth and damage in a variety of contexts. This includes the differentiation of damage in residential and non-residential buildings.

The ability to capture the unique impact of boh fluvial and pluvial perils.
Alternative Living Expenses(ALE)
The indirect costs of evacuation, accommodation, and other expenses are explicitly modelled.
>10,000 Unique Damage Functions
Based on relevant combinations of building, peril and coverage characteristics.

The coastal component
captures flood risk due to

Accounts for the likelihood of flood warnings and water contamination.
Loss calculations derived for both high-frequency and low-frequency events.
A consistent view of risk across the whole UK.
Realistic loss simulation.
Long and short duration flood damage differentiation.
Accurate determination of damages based on a property's characteristics.
Generalisation of property characteristics in the absence of precise data.
