Fathom data provides an invaluable source of information that can be used to mitigate against, or respond to extreme events globally.
The Human Impact of Floods: a Historical Review of Events 1980-2009 and Systematic Literature Review. Doocy S, Daniels A, Murray S, Kirsch TD. The Human Impact of Floods: a Historical Review of Events 1980-2009 and Systematic Literature Review. PLOS Currents Disasters. 2013 Apr 16 .
Over the twentieth century, floods accounted for 6.8 million deaths worldwide.
By 2030, South Asia could face $215 billion in GDP exposed annually, an increase of more than $193 billion.

US Environmental organisation
The Nature Conservancy is a US based
environmental organisation aiming to conserve and restore natural environments.
Among their many projects, The Nature
Conservancy are exploring the possible restoration of wetland systems that have
been adversely impacted by flood defence structures.
Further to this, The
Nature Conservancy are also more broadly interested in flood risk, particularly
in identifying large scale exposure to flooding across different demographics,
and how this exposure may change in the future, given changes to climate and
land use management.
Broader challenges include:
many people are presently exposed to flooding in the USA, and how many will be
exposed in the future?
are the impacts of man-made structures and natural flood plains?
any of these areas be restored to their natural state, with the added benefit
of mitigating flood risk?
will the development of protected areas impact the number of people exposed and
what are the benefits of retaining protected areas as floodplains?
Fathom have built
bespoke large scale models that allow The Nature Conservancy to explore
floodplain connectivity and identify structures that may be removed.
Our hazard data have
been combined with maps of current and projected population, land-use and GDP
across the conterminous United States.
This has permitted answers to previously
unknown or poorly answered questions: an accurate estimate of exposure in the
USA and the mitigatory benefits of avoiding development of natural areas.
A number of peer-reviewed
papers have been published based on this collaborative research, enhancing
understanding of flood exposure in the United States.
Furthermore, The Nature
Conservancy are able to inform clients not only of ecosystem benefits in the
preservation of natural land, but also benefits in terms of avoided flood
powerful models are uniquely able to support our work evaluating potential
nature-based solutions at large scales.
Working with them has been great - they
are highly skilled professionals who have delivered products on time throughout
every phase of our work. //

Catastrophe model developer
Impact Forecasting are a world leading model provider, developing catastrophe models across multiple perils and territories.
Although Impact Forecasting have a suite of products available to cover multiple perils, including an in house European flood model, there are areas of the world in which collaboration with external partners enables Impact Forecasting to offer greater model coverage. These areas include South and Central America, areas in which there is significant demand from clients for flood coverage.
Fathom have developed methodologies to enable robust flood models to be built, without the need for local information to be included. This allows flood hazard data to be produced over large, previously unmodeled territories.
Fathom have partnered with Impact Forecasting, using their cutting-edge tools and methods developing accessible catastrophe models, to develop flood scenario models covering all of Latin America.
A collaborative effort between SSBN and Impact Forecasting has yielded scenario flood models covering all Latin America. This provides their clients to assess their potential losses large, and previously unmodeled territories.
// The Fathom flood hazard data allows us to offer clients a solution for the Latin American market. Insurers and reinsurers in this territory are now able to view and assess the flood risk in their portfolio based on historical scenarios at a range of return periods.
The scenario model for Latin America is fully implemented in ELEMENTS, Impact Forecasting’s catastrophe loss modelling platform. //

US Environmental Protection Agency
US Environmental organisation
The US Clean Water Act stipulates that wetlands within the 100-year floodplain should be protected areas. Previously, the EPA have used FEMA flood maps to determine floodplain extent.
These maps, however, are spatially lacking since they generally focus on urban areas. The EPA have employed a number of relatively poor approximations to ‘fill in’ the gaps in FEMA data, including soil-based indicators and distance proxies.
The EPA required a more robust delineation of 100-year floodplains, so utilised our hazard data.

In combination with research at the University of Bristol, a map of wetlands across the continental United States was intersected with our 100-year hazard layer.
The location, number, combined area and characteristics of wetlands within the 100-year floodplain was generated
