Quote: To determine exactly where and how high to build these levees, the engineers have enlisted the aid of a 3-D computer-simulation program called ADCIRC (Advanced Circulation Model). ADCIRC incorporates dozens of data points—including seabed and coastal topography, wind speed, tidal variation, ocean depth and water temperature—and charts a precise map of where the storm surge would inundate New Orleans. The category-5 levee idea, though, is still in the early planning stages; It may be decades before the new barriers are completed. Until then, locals had better keep praying to Helios.
