Hurricane Katrina Storm Surge and Wind Speed Estimates

Katrina Estimates


The open coastlines of Louisiana, Mississippi, and Alabama needed a system to help estimate a hurricane’s damage and the effects it would have on the coastlines of the southern United States. ARA was asked to help generate estimations of storm damage, storm surge heights, wave heights, and wind speeds.


To help forecast hurricane damage, ARA:

  • used HURSURGE and HURWIND computer models to produce results
  • created maps of inundated areas, maps of wind speeds, and maps of wave heights over the flooded portion of the coast
  • produced time series of wind speeds, wave heights, and flood depths at a number of locations to aid in the determination of the sequence of wind vs. flood damage


ARA validated the resulting hurricane computer models of wind and flood damage through comparisons to observed flood and wind data.
