How was the risk model tested to ensure accuracy?
The IPET ran Katrina through the risk model and got almost the exact same results (areas that flooded, damages, etc.) that Katrina actually produced. Also, the new hurricane modeling method used in the risk assessment was validated using information from six historic storms. These storms, when run through the hurricane model, produced the same storm results. These storms were: Rita, Katrina, Camille, Ivan, Betsy and Wilma.
