Climate Change

Accurately predicting global flood risk
is essential to
our future.

Fathom’s modelling frameworks allow complex, 2D flood modelling to be undertaken over large scales, covering all river systems. One of the key benefits of these semi-automated modelling structures is that they can be rapidly re-run for different scenarios, including for future climates.
Fathom have deployed their modelling frameworks to simulate future flood risk across many territories worldwide. This includes in Bangladesh, where the World Bank used Fathom’s modelling frameworks to explore potential future exposure nationwide.

Fathom provided future flood maps of the country that were used to identify suitably risk-averse locations for infrastructure investment, including the building of new power stations. The World Bank has also relied on Fathom’s models to provide future views of risk across Argentina.
Fathom have also built future flood models of the Pacific Northwest region of the United States, covering both riverine and coastal inundation for the University of Washington.  

Lastly, as part of a large collaborative project including partners at the Massachusetts Institute of Technology (MIT), Fathom are building future flood hazard data of the entire conterminous United States. Fathom are explicitly modelling fluvial, pluvial and coastal inundation for the entire country.
This large piece of modelling work includes the coupling of Fathom’s hydraulic model framework with an ensemble of 21 climate models.

Fathom will also couple their modelling framework with third party current and future hurricane models produced by colleagues at MIT. This project, brought together and led by The First Street Foundation, will yield the most complex and comprehensive view of both current and future flood hazard across the United States.
