water tunnel
Underground liquid conduit
A water tunnel is an underwater passageway, either natural or constructed.
Engineering water tunnels carry water for municipal supply, hydroelectric power, or irrigation.
In research, a water tunnel is a facility where water flows past objects to study hydrodynamics—the liquid equivalent of a wind tunnel: The submarine model was tested in a water tunnel.
