Floods devastating Prague subway - photos

pics from Prague metro in late summer 2002 showing devastating power of quincentennial floods (in Czech rep) that hits many countries in Europe that year

subway map - ticked stations were out of order


Line A (four station damaged including two transfer stations)
you can see where was the upper reach of the water, mud was everywhere

Is it because the snow from winter is melting too rapidly?

Sad to see the damage to Prague Metro. But good to hear that it's apparently been fixed up. Beautiful subway. The traincars, stations & ecalators look like Moscow Metro!

yes, it was roughly fixed within half a year but it was quite expensive...

yes, today most stations should resist same floods plus increased 60cm. The main problem during floods in 2002 were cable bushing - they don't seal enough. Somewhere weren't instaled closing valves - nobody knew it and nobody took care about it. This subway was designed to resist nuclear explosion but after these floods we could see there were weak links... somewhere closing valves were missing and were only thin walls instead, that couldn't resist such a enormous hydrostatic pressure (several ten meters).
These floods have enlightened us enough not to repeat same mistakes. But there are about four shallow stations that can't be protected from water otherwise they could swim up as a bubble during floods, we take this into account.

^ in some stations water reached 3 meters above ground so it was impossible to protect them. But in some stations water got only through deep underground tunnels because some closing valve gates weren't activated, some were even missing (despite project documentation include them) and somewhere cable bushing didn't seal enough, that was the main problem.

I think I've just developed a new phobia -- fear of flash-flooding in subways. Hope I don't freak out next time it rains!

Never seen this before. The scenes would make for a good horror movie.

http://www.radio.cz/en/html/povodne2002.html heres a link if anyones interested in more pics of the floods.

I thought that some of the flood gates did not close in time because of maulfunctions and because of the weather service downplaying the warnings and underestimating the size of the flood. Isnt that why the Prague Zooz lost a bunch of animals including some elephants, hypos, etc. not to mention that seal that swam from Prague to i think Hamburg, until the polution in the water finaly got to it. By the way I love those new floods walls that they have ready to set up on the banks of vltava now(I think they actual put them up this week because of the floods).

Hey do you have any info when their finaly going to extend line B(or the green line) to the airport and build line D? And what is the actual time line to build the circle route?

Iv been trying to get some info on this, but find it hard since i dont live there anymore.

My goodness! It looks like the aftermath of a terrorist attack or a mega tsunami! It must have cost hundreds of millions to fix!
