I have long been interested in bridges which carry water, especially those which carry water over other water.
Aqueducts are man-made devices generally designed to carry water from one place to another. This can be a distance of a few meters or hundreds of kilometers. The water can be for human consumption, mechanical use, or relocation to a drier area (agriculture). They can carry other other liquids, e.g., sewage. They can also be used for transportation, such as canals.
They are usually ditches or tubes. If raised, they are more correctly called water bridges, but the term aqueduct is more common. A similar but different term is viaduct, for bridges which carry roads, etc.
This global collection is only a starting point, and it is limited to those areas where the Google Earth images are of high resolution. It only contains those examples where the water is elevated in a bridge or other device. It is not a collection of long, ground-level canals.
Additions and corrections will be gladly incorporated, but maintenance will not be frequent. Credits to the original posters appear in the attached file.
Some helpful sources:
Wikipedia Aquaducts and its national variants in other languages
UK: Waterways Information and Pennine Waterways

WilloxH,
With version 2 of the aqueducts file, I've added more than 30, including yours from Mexico. It was interesting to see your Web site about Mexico in the French language.

Hallo Price
A few more in Holland,
we call them tunnels, not Aquaducts.
only the short ones we call Aquaducts, like the one at Gouda.
One is the Hemweg tunnel, its a railroad tunnel. ones there whas a bridge, (see picture) the bridge whas around 3000 feet to the right.
The other one is the Piet Hein tunnel, the Piet hein tunnel makes a nice curve, as you can see at the placemarks.
Dutch names :
the Amsterdam aqueduct, ij tunnel
Tuindorp aqueduct, Coen tunnel
Markermeer A-10 aqueduct, Zeeburger tunnel
Rotterdam aqueduct, Maas tunnel
Vlaardingen aqueduct, Benelux tunnel
I also includes two in Antwerpen. dont know the name.
and the Heinenoord tunnel,
Here some pictures about the tunnels and aquaducts, sorry most in Dutch.
Greetings

That's correct sasroodkapje.
Price,
I've got (all) Dutch aqueducts in a kmz file (got it from nl.wikipedia.org). You can replace your entries with mine if you want too. My entries have their original Dutch names.

Hi Simon..
Thats a nice collection, this are Aquaducts, only at 4 I have questions.
Langdeel aquaduct
Jeltesloot aquaduct
Both are bridges,
Woudsend aquaduct
Your placemark tells "under construction", do they plan a aquaduct there.?
de Geeuw aquaduct
I dont see an aquaduct here,
the rest is great, I did not knew there where so many of them..
Thanks and greetings

SimonTemplar76,
I've included your newly noted Dutch aqueducts in Version 3. I gathered the 5 Frisian aqueducts which are under construction in a separate folder under the Netherlands, so that users will understand why they don't appear in current imagery.
Thanks for the helpful input.

sasroodkapje,
The attached file is a collection of tunnels under water channels, a couple of which were removed from the aqueduct collection and others which were from those you provided.
When is a water bridge just a water channel under which a tunnel has been dug? The aqueduct collection has some borderline cases.
It seems clear that if the water channel is simply a concrete or steel passageway which is constructed above another route, that it's a water bridge. Conversely, a long road tunnel dug deeply under a harbor waterway, becomes a river under which a tunnel has been dug.
BUT, is the difference just the amount of dirt between the two levels? Your example in Zelzate, Belgium is a good borderline case. It's very similar geometrically to the aqueducts in Sneek, Netherlands, but those have no dirt between the two levels.
I hope that the geometry, etc., can determine the choice, because construction methods cannot be reliably obtained for historical aqueducts.
Comments, observations, etc., will be welcome.
