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
Flood defence resilience and adaptation.
Large area master planning and scheme development
Flood loss calculation
Quantifying increases in flood exposure due to climate change
Developing climate resilience and mitigation strategies and local actions
Our technology
Fathom offers a variety of data and models designed to enable engineers to confidently assess flood exposure and make informed decisions.
Quote I’d like to thank the effort of regional flood planning groups, its members, technical consultants, the public and other agencies who have been putting in a lot of time to put together regional flood plans, essentially going to come together as the first State Flood Plan for Texas.
Read Case Study
Quote Fathom’s most recent release – Fathom-Global 3.0 – provides flood maps for anywhere in the world, and at improved levels of detail, providing information to help decision makers better manage their future flood risk by considering climate change and the associated uncertainty.
Quote Aqua Strategies is proud to work with Fathom on this truly innovative method for greatly improving how we develop flood risk maps in Texas. Successful delivery on this project demonstrates possibilities for the remaining 49 states, and beyond.
Model features
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.
