"New Orleans sinking faster than thought

Published:

Some months back if memory serves me, I posted something to the effect that since New Orleans is built on silt which sinks, the levees would also be sinking lower when they were originally built due to that phenomenon.  Well looks like this latest proves that assertion .... which was no more than simple common sense.


"New Orleans sinking faster than thought

WASHINGTON - Everyone has known New Orleans is a sinking city. Now new research suggests parts of the city are sinking even faster than many scientists imagined — more than an inch a year.

That may explain some of the levee failures during Hurricane Katrina and it raises more worries about the future.

The research, reported in the journal Nature, is based on new satellite radar data for the three years before Katrina struck in 2005. The data show that some areas are sinking four or five times faster than the rest of the city. And that, experts say, can be deadly.

"My concern is the very low-lying areas," said lead author Tim Dixon, a University of Miami geophysicist. "I think those areas are death traps. I don't think those areas should be rebuilt."
