Yes, actually I do--and probably better than you do, having seen real Mississippi River flooding in action several times in my life. But there are lots of tractors and pumps in South Louisiana, plus I'm sure there are tractor-trailer mountable portable pumps that can be brought in.
It's a case of making use of ALL the potentially available resources to get the job done. Just like N.O. "should" have used their damned school buses to move/evacuate people.
For the volume of water to be moved, with the head pressure needed to raise the water high enough to go over the sea wall or back into lake ponchatrain, there arent enough fire trucks or portable pumps in the US right now to move that much water in less than 6 to 8 months
Not for nothing but they could bus the water out. Now that they have buses. /sarcasm off
