Someone's going to have to explain this to me.

The way I see it:
(1) Tunnel: underwater
(2) Manhattan: above the water.
(3) Generally, water does not flow uphill.
(Ergo) Blowing a hole in the tunnel poses no real threat to Manhattan. Pressure differences and the vinturi effect. I.E. the sudden rush of water into the tunnel, which is under the water, and the pressure of the water above it would have forced water out the opening of the tunnel. After a few minutes the pressures would equalize and return to hydrostatic pressure. The tunnel would be flooded and a fair amount of water would have shot out of the tunnel entrances.

I doubt it would be enough to flood more then the nearby buildings and it wouldn't have been the massive flood the people were hoping for but water would come out of the entrances. The main effect would be the loss of the tunnel and the killing of anyone in it along with the destruction of the trains in the tunnel.
