It is not, but https://en.wikipedia.org/wiki/Aqueduct_(water_supply)
looks more similar and even lists qanat as a form of aqueduct.

Perhaps we could do it like this:
waterway=aqueduct
and:
aqueduct=bridge — for the "usual" aqueducts placed overground on pillars,
aqueduct=surface — for the ground-level ones, e.g.
https://en.wikipedia.org/wiki/File:Arizona_cap_canal.jpg
aqueduct=qanat — for qanat

However it might create confusion with already existing bridge=aqueduct.
