Looks like Osaka has been stealing ideas

Very interesting, I was not aware about this. Thanks for this curiosity.
I did some searches and discovered that in England it's a stone arch(decoration) over a tiny straight up floodgate, but in Netherlands... that's truly something else, same floodgate type with same tech but double arched floodgate, they started to build it in 1960, first part finished in 1965, the full project finished in 1970

Ofnuts snip at me, I posted some photos of the Gateshead Millenium Bridge, which works in a similar way.
However, as a civil engineer I am always interested in big projects. In the UK the Thames barrier is impressive. https://www.gov.uk/guidance/the-thames-barrier

Indeed, the Thames barrier is impressive, on wikipedia they got some great pictures.

But I'm not sure if using human as counterweight to rotate the wheels was a good idea ➤ https://upload.wikimedia.org/wikipedia/commons/8/85/Thames.barrier.4.london.arp.jpg

Something I don't quite get about such a barrier on a river is that you get water from upstream too. So the idea is that the Thames is technically a rather small river and that the closed estuary is large enough that it won't fill during a single tide?

That was bothering me as well, I might have a beginning of "understanding", take a look at low tide ➤ https://www.google.com/maps/search/thames+river/@51.497739,0.0330642,1042m/data=!3m1!1e3?hl=en-US
