    MANAGING FLOOD RISK ON A GLOBAL SCALE

    31% of global economic losses due to natural hazards are caused by flooding, with the ten costliest floods between 1980 and 2014 causing an estimated US$187 billion in overall losses. Accurately predicting global flood risk is therefore essential to our future. Fathom's mission has been to create the most detailed, accurate and comprehensive flood risk map of the entire planet. Through its US and Global flood hazard data and models, they aim to transform risk assessment, planning decisions, disaster response and emergency preparedness.

    UNDERSTANDING YOUR FLOOD EXPOSURE

    Fathom's probabilistic models build on their world leading and validated flood hazard methodologies, allowing exposure to be easily quantified across entire portfolios. Among their numerous applications, these probabilistic models will permit clients in the (re)insurance sector to obtain a defensible estimate of their asset exposure.

    US Flood

    The Fathom US Flood Model achieves a resolution of 30m, while their bespoke models can be as fine as 0.5m. Working with researchers at the University of Bristol, Fathom's US30 model was compared to flood maps produced by the Federal Emergency Management Agency and United States Geological Survey. The data attained a very high level of fit to FEMA flood maps, capturing over 80% of the flooded area specified.

    FLOOD RISK MAPPING FOR THE ENTIRE PLANET

    Fathom's state-of-the-art flood hazard data make it easy for clients to assess their exposure, mitigate against risk and respond to extreme events anywhere. Fathom's flood hazard data has global coverage at 10 different return periods: 5, 10, 20, 50, 75, 100, 200, 250, 500 and 1000 year events. Data resolution varies by territory and is determined by the accuracy of available terrain data for each region.

    The accuracy of Fathom's hazard data was demonstrated during the 2011 monsoon season in Thailand where severe flooding spread through the provinces of northern, north eastern and central Thailand. Fathom's Global data prediction achieved a comparison hit rate of >85% with a Critical Success Index of 0.72 for this site.
