News > Army Corps Report on New Orleans Floodwall Failures
From Popular Mechanics:
IPET determined that, after 35 years structures at the Inner Harbor Navigation Canal were more than two feet lower than their design specifications. Other discrepancies, such as outfall canals built one to two feet below their specified elevations, were the result of designs being based on water level datum while construction was based on geodetic vertical datum—the two are not equivalent, spatial and temporal variations between 0.2 and three feet were found between the two.
There's also news that the New Orleans area is sinking faster than previously thought, with some areas sinking as much as three feet in 30 years.
