hydrology
I've been watching/reading Sandy coverage obsessively. Having survived a couple of freakish and/or record-breaking natural disasters in the past few years, I have so much sympathy for the Eastern Seaboard -- and I'm worried about everyone's insurance coverage. But I'm also trying to figure out some of the hydrology involved... in our flood, it was a simple traffic jam of water, as it were. ALL THE WATER was trying to get into the Mississippi at once. It couldn't all fit. Once the water that was first in line (and second, and third, and fourth...) eventually got out of the way, the rest of it drained away just like it should have.
So I understand why the NYC subway tunnels are still full of water -- the water came over the surface, filled in the holes, and now has no way to get out. But what's the hydrology of Hoboken? If the flood water is storm surge from the river, why hasn't it just drained back into the river? Is the river still running high? Or is there some barrier in the way? Or am I misunderstanding how the water got there? Scary stuff, either way. I just like to understand things like this.
