Pumping the tunnels

[kim]

Nah - tugs pump lakes and harbors - there are tugs all along the seaboard.

A portable pump works to remove an estimated 30 million gallons of
floodwater from New York's normally busy Queens-Midtown Tunnel.

It doesn't look deep, because that is at the edge; where as the tunnel continues into "valley" until it begins to curve up to the other end.

Quote: It’s going to take hundreds of pumps, including ones powerful enough to
drain an Olympic-sized swimming pool in less than 15 minutes; the U.S.
Army Corps of Engineers’ National Unwatering SWAT Team; and at least
several more days to get the job done.

It looks to me that they had to drain the "bath tub" that makes up the
World Trade Center, because it was the highest level of water, and it
probably empties most of the subway lines in the area as well.



So it sounds as if the structure of the tunnels can handle their being flooded, as they were designed so long ago.

I cannot wait to see the animation model of the flooding.
