Engineering Flood Resilience
Understand flood hazard and risk with Fathom’s comprehensive,
scientifically proven flood data.
Fathom’s flood maps and models enable engineers, infrastructure and asset management specialists to rapidly assess their exposure to flooding and develop adaptation and resilience strategies to combat the impact of climate change.
With an academic pedigree spanning over three decades, Fathom’s products are a culmination of the most robust scientific flood research and development available.
Customers can easily access our data in a GIS-ready format and incorporate it into their projects to make informed decisions swiftly. Our data sets are ideal for engineering teams working from local to global scales who need to determine flood risk for mitigation and resilience projects for current and future climate scenarios.
Existing users of our data have told us that our products have helped them in:
Global portfolio screening
Rapid high level review of a large number of global assets.
Site level analytics for assets identified at risk
Detailed site analysis
For prospecting, selection and due diligence.
Asset management

Terrain data

Fathom’s flood maps are underpinned by the best globally available terrain dataset for flood modelling – FABDEM+. The true global bare-earth terrain data combines FABDEM with high-quality laser altimeter (LiDAR) data gathered as recently as 2023.
Fathom’s team has been at the forefront of building market leading Global Terrain Data since 2017, when we first published the methodology for MERIT DEM.
Multi-peril

With sub-perils explicitly modelled to build a comprehensive understanding of the impact of different flood sub perils on different assets.
Climate data

In a rapidly evolving climate landscape, relying solely on historical records can lead to substantial mis-estimates of hazard. Fathom’s products incorporate data from relevant climate models, meaning that Fathom’s technology accounts for the growing impact of a non-stationary climate.
Return periods

All of Fathom’s products simulate flood events for 10 return periods ranging from the 1-in-5 to the 1-in-1000 year flood. This enables users to understand the implications of a wider range of flood events and allows for a better understanding of event frequencies.
Flood depths

Flood depths and extents are critical to understanding the impact and severity of flooding for all three flood sub perils.
Risk Scores

Fathom’s flood data are now also available as Risk Scores. Offering a simple yet powerful way to compare the flood risk for assets across your portfolio. Available in two forms, Relative Risk and Risk Category, the metrics are designed to deliver a consistent method of understanding how flood risk varies from one location to another.
