UK Flood Map
Fathom-UK offers comprehensive flood hazard modelling for
the whole of the United Kingdom
Fathom’s UK Flood Map, Fathom-UK, offers an alternative view of flood risk against existing government data, projecting changes in hazard across multiple different climate scenarios. Achieved through combining world-leading research and cutting edge modeling techniques with data like UKCP18, UK Flood Map offers users to critically assess the impact of flood risk against any portfolio, book of business or asset.

About the map Created by some of the world’s leading academics and scientists in climate risk and hydrology, Fathom’s UK Flood Map is based on pioneering methods developed in-house
Underpinned by decades of peer-reviewed research, our model couples decades of scientific research with the latest hydraulic modeling techniques.
The result is flood hazard data that can provide high-resolution predictions for current and future climate scenarios – a first for flood modeling in the UK.
By integrating these datasets into Fathom’s hydraulic modeling framework, UK Flood Map yields multiple return periods for every river channel in the country.
We have achieved this through Fathom’s unique channel solver methodology, which explicitly represent river channels in the absence of accurate hydrographic information.
When incorporated alongside precise terrain data, multiple perils and defense algorithms, users are presented with a dataset that effectively represents the impact of climate on flood risk, rather than relying solely on historical records.
