Per the wiki "Use waterway=canal for man-made open flow (free flow vs pipe flow)
waterways used to carry useful water for transportation, hydro-power generation OR
irrigation purposes." E.g. there are a range of purposes for which waterway=canal
is used.
But see: https://en.wikipedia.org/wiki/Aqueduct_(water_supply)
"An aqueduct is a watercourse constructed to carry water
...in modern engineering, the term aqueduct is used for any system of
pipes, ditches, canals, tunnels, and other structures used for this purpose.
...The simplest aqueducts are small ditches cut into the earth"
