By 2050 there will be a
increase in the number of properties in the UK at substantial risk of flooding.
By 2050, over 1.3 million properties in Great Britain will be at risk of substantial flooding. Our data provides the right people with the correct information - so that they can mitigate risk.
Fathom-UK helps to quantify flood risk and asset exposure for multiple climate scenarios: 2020, 2030, 2050 and 2070. This is the first flood model in the UK to factor in the impact of climate change, rather than just relying solely on historic records. By doing so, Fathom takes the UK's understanding of flood risk one step further and supports users to understand how risk will change over time.
With new PRA legislations requiring insurers to have a greater understanding of flood risk in the future, our model provides accurate predictions for pluvial, fluvial and coastal perils. Fathom-UK's inclusion of 10 return periods means that users have access to a wide collection of event frequencies.
The hydraulic model projects changing flood behaviour arising from Intergovernmental Panel on Climate Change (IPCC) climate model ensembles.
Future climate scenarios follow an emissions pathway from the UKCP18 dataset. Projections are made under the Representative Concentration Pathway 8.5 trajectory.
Fathom-UK yields a complete
index of flood defences for the
whole of the UK.
Fathom's unique levee detection algorithm enables Fathom-UK to detect and incorporate defence data where it may not be available publicly.
