KatRisk Releases High Resolution Flood Risk Data for the United States

Berkeley, California (EastBayDaily) — The KatRisk data extends beyond FEMA Flood Insurance Rate Maps by covering the entirety of the lower 48 states, providing flood depth levels in addition to flood extents, and modeling both riverine and surface water flooding in all areas. The US release builds upon previously developed and released flood risk data for the region of Asia extending from Thailand to Japan and Indonesia to China.

“We are very excited about this initial release of flood risk data for the United States. We are confident that the level of detail and comprehensiveness of the data will provide unique capabilities for anyone trying to quantify flood risk. This was illustrated by the recent flooding in Pensacola that showed flood risk in areas outside of FEMA flood zones but identified by the KatRisk data," says Dag Lohmann, CEO and Co-Founder of KatRisk.

Modeling flood risk at a 10 meter resolution with over 80 billion grid cells posed significant computational challenges. KatRisk was able to overcome those challenges by utilizing the resources of the TITAN supercomputer at the Oak Ridge National Laboratory. The hybrid GPU-CPU architecture of the Oak Ridge Leadership Computing Facility is a perfect match for the modeling approach taken by KatRisk.

This release of flood risk data is the initial stage of a broader development agenda of flood risk quantification products and services for the United States as well as the rest of the world. KatRisk has already built tropical cyclone (TC) track models for the Atlantic and Northwest Pacific Basins. These track sets will be used to model storm surge and TC related rainfall resulting in a complete quantification of correlated coastal and inland flooding and wind. A free version of our wind model can be accessed at http://www.KatRisk.com.
