In the 1830s, when all they had to figure with were paper and pencil and an early form of the slide rule, the US Army Corps of Engineers succeded in altering the course (http://riverweb.cet.uiuc.edu/ENVIRON/ENVIRO8.htm) of the Mississippi River. Today, with sophisticated computers to perform calculations and mapping tasks for them, the Corps can't even manage to draw a proper flood map (http://talkingpointsmemo.com/news/2007/11/mistakes_made_in_new_orleans_f.php).
A system of flood gates and pumps built since Hurricane Katrina to help alleviate flooding in several New Orleans neighborhoods may not be as much help as authorities first said.
The Army Corps of Engineers released flood risk maps on a block-by-block basis on June 20, but didn't include some technical data, preventing independent assessments of the accuracy of the maps.
The maps showed that the improvements made to the city canals' drainage systems would reduce flooding during a major storm by about 5.5 feet in Lakeview and nearby neighborhoods. The maps were based on a storm that has the likelihood of occurring at least once in 100 years.
But in a report released Nov. 7, Corps scientists estimated that the actual benefit the system would provide would be just 6 inches.
Robert E. Lee would have eaten these guys for lunch.
