You have found an interesting website but your link doesn't work - this one does

https://www.showcaves.com/english/explain/Karst/Estavelle.ht...

BTW sorry to burst your bubble, but exactly the same article is available in German

https://www.showcaves.com/german/explain/Karst/Estavelle.htm...

and I have the nagging feeling that it's the GERMAN VERSION that is the original version.

a clue: the domain name "showcaves.com" is registered to someone in Germany

It is the right terminology definitely samo je problem u tome što treba poznavati materiju za koju se traži prevod. :-)

Another mechanism is based on the different specific gravity of salt water and fresh water. In communicating pipes, the water level is normally at the same level, but when sea water with a higher specific gravity is filled in on one side, the water level is lower despite a state of equilibrium. A cave with an undersea outflow and an additional outflow just above sea level can use this effect in a special way. The karstic water level sinks below sea level due to the above-ground outflow, which causes sea water to flow into the cave system at the underwater entrance.

It's a reportage transcript? You mean it was written by a journalist?

That would explain "pipes" in kart terrain. You could loosely call underground canals in karst "pipes" but that is definitively not the right terminology.

If these "pipes" look like "connected / communicating pipes" to this journalist it's because often (but not always) these canals look like a grid once the whole cave is mapped.

Феноменологију 'karsta' је у највећој мери истражио, објаснио и дефинисао наш научник Јован Цвијић. Чак је и добар део његове (тј. српске) терминологије усвојен и у светским размерама, што је баш веома ретко. Стога, не треба тражити решења искључиво у некаквој 'UK' терминологији - у овом (али, нажалост, веома ретком) случају и они су преузели пуно тога од нас.

It's not It's a reportage transcript. It might not have been written by an English person though.

Are you sure that your text is not
a translation? A rather approximative one ...

The word "pipe" is normally used for man-made "pipes", I have never seen it used for underground canals/passages in karst terrain (and I can't find ANY occurrence on the Web of "pipe" being used to mean "underground river in karst terrain")

https://en.wikipedia.org/wiki/Karst

https://en.wikipedia.org/wiki/Subterranean_river

You can get several sinkholes draining in the same underground river/canal - that's what they are talking about - there are no natural "pipes" in karst.
