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.
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
Fathom offers a variety of data and models designed to enable engineers to confidently assess flood exposure and make informed decisions.
Fathom’s models are underpinned by the best globally available terrain datasets for flood modelling. Our global base data are currently being upgraded from MERIT-DEM to a new dataset based called the Forest and Buildings Removed Copernicus DEM (FABDEM).
Our team collaborated in the creation of both ground-breaking datasets. Over certain parts of the globe even higher quality national terrain datasets are available, usually underpinned by laser altimeter data (LiDAR) or photogrammetry derived datasets. Wherever possible these national data are used, including across all of our country specific models.
With sub-perils explicitly modelled to build a comprehensive understanding of the impact of different flood sub perils on different assets.
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.
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 and extents are critical to understanding the impact and severity of flooding for all three flood sub perils.
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
