Flood Responses to Climate Warming on Tribal Lands Using High‐Resolution Hydrodynamic Modeling
In a Nebraska flood model, warming did not make floods bigger or more frequent overall.
Tianjiao Pu, Gabriele Villarini et al.
A detailed flood map for the Santee Sioux Nation in Nebraska did not show much worse flooding under a warmer climate. The team built the map using 10 meter resolution, which means it shows flood details down to about the length of a bus. They compared 42 years of real weather data to a hotter, climate changed version of the same storms. Floods did not get much bigger or more frequent overall. Instead, some low spots and side streams flooded a bit differently, while the total flood risk stayed close to the same.
The span of weather data used to compare normal storms against warmer, climate changed storms.
One Nebraska tribal site modeled, not a national flood forecast.
