Sub-a′que-ous tube.
A pipe or tunnel (according to size) laid beneath the water as an aqueduct or viaduct.
James Watt's submerged aqueduct across the bed of the
Clyde is an example.
It is a pipe with articulated sections, whose flexibility permitted it to be put together at the surface
[

of the water, and then sunk into position.
