Impact/Purpose:
Flooding damages analysis to support quantification of changes in climate-driven risk.
Description:
A growing body of recent work suggests that the extreme weather events that drive inland flooding are likely to increase in frequency and magnitude with a warming climate. These changes are likely to increase flooding damages in the future. We use hydrologic projections from 29 downscaled climate models and 2 emissions scenarios to estimate changes in the frequency of historical 1% annual exceedance probability flood events at approximately 57,116 locations across the contiguous United States. We link these flood projections to a database of assets within mapped flood hazard zones to estimate inland flooding damages throughout the CONUS over the remainder of the 21st century.
