The computer models, which are being run at the Louisiana State University's Center for Computation and Technology, help to inform emergency planners what roads will flood and neighborhoods cut off.
They are being used to help determine the best staging areas for positioning people and supplies needed for the recovery, said Twilley.
"They can look down at neighborhood scale and say 'on this street along the levy we're going to have water this high,' and plan accordingly," Dietrich said.
Comparing the capability today with that at the time of Katrina, Dietrich said:
"I think we have a very strong understanding of how hurricane wave storm develop and how they can threaten a coastal environment."
the new supercomputer capabilities are much better now than they were during Katrina 7 years ago. They help position people and supplies in the areas needed for the recovery, and determine which roads will flood.
