A study funded by the Army Corps of Engineers found that grass can effectively armor the levees in Louisiana and prevent erosion from surges caused by 500-year storms. Researchers used a wave-overtopping simulator to conduct the tests and were impressed with the grass' resiliency. Tim Doody, president of the Southeast Louisiana Flood Protection Authority East, said the agency should learn how to efficiently grow the grass, saying "what good will grass do without the knowledge to grow it."
