Fathom-US

Fathom-US CAT

The first fully
peer-reviewed and validated US flood catastrophe model.

The model builds upon the Fathom-US inland flood model, transforming leading hazard data into many thousands of years of plausible flood events.
Fathom-US CAT has been built
to work in the Oasis LMF and is
available in Nasdaq ModEx.

Latest
data
Fathom-US CAT uses the
latest US hydrography data from the USGS.
