Water Bridge in Germany .. What a feat!
Six years, 500 million euros, 918 meters long ........now this is engineering !
This is a channel-bridge over the River Elbe and joins the former East and West Germany ,
as part of the unification project. It is located in the city of Magdeburg , near Berlin .
The photo was taken on the day of inauguration.
To those who appreciate engineering projects, here's a puzzle for you armchair engineers
and physicists.
Did that bridge have to be designed to withstand the additional weight of ship and barge traffic,
or just the weight of the water?
Answer:
It only needs to be designed to withstand the weight of the water!
Why? A floating ship always displaces an amount of water that weighs the same as the ship,
regardless of how heavily a ship may be loaded.

Not exactly, but we have a river run under a lake out here.
The Las Vegas wash, which is the sewer run-off from town is now considered a river as it flows 12 months. Problem is, the developers of Lake Las Vegas wanted to put a high end housing community and private lake in the path of the wash. Solution? Build the lake over top of the wash so that the water from the lake and the sewer water from the wash never mix.

Be a great place for one of those 007 flying boat chase scenes! Yeeha!!

Wouldn't it depend on how the water is contained? Judging by the elevation over the Elbe there is some sort of lock system... correct?
If the locks were closed, the water could not be displaced. I'm sure that there is a water "vent" system or something that accounts for this but I don't think it would be as straight forward as the answer made it sound.

I've seen (on TV) a smaller scale version of that type of setup in England. :iagree:
Still very cool though. :cheers:
Ever seen a river over a river?
no, but I've seen a river in the ocean...
it's called the Gulf Stream :dance:

Unbelievable, never seen anything like it!

When you put ice cubes into a glass of water...where does the water go?

Both of those have some very impressive engineering.
