Now the city is really in trouble. Having seen and worked against flooding I doubt those breaches in the levees can be closed by dropping sandbags from the air.
The potential area of flooding through the reported breaches is some 75 square kilometers. The average water level would be over 1 meter.
That are up to 75,000,000 cubic meter of water that will not evaporate or vanish in the ground. As New Orleans lies below the natural water level, they will have to be pumped out.
The biggest transportable salvage pump I could find on the net does some 750 cubic meter per hour and there are not many of those around.
It will be a long, long time before New Orleans is inhabitable again. Given the extreme dangerous location, one might want to ask if that is desirable at all.
The question of course is who will have to take the blame. Here is a hint:
It appears that the money has been moved in the president’s
budget to handle homeland security and the war in Iraq, and I suppose
that’s the price we pay. Nobody locally is happy that the levees can’t
be finished, and we are doing everything we can to make the case that
this is a security issue for us.
