A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water. It functions similar to a recirculating wind tunnel , but uses water as the working fluid, and related phenomena are investigated, such as measuring the forces on scale models of submarines or lift and drag on hydrofoils .
The Garfield Thomas Water Tunnel is the facility's largest water tunnel. [7] The 100 feet long, [ 5 ] 32 feet high, [ 5 ] 100,000 [ 1 ] gallons tunnel is a closed-circuit, closed-jet. The system is powered by 1,491 kW (2,000-hp) pump, with a 4-blade adjustable pitch impeller and can produce a maximum water velocity of 18.29 m/s (40.91 mph).
Water tunnel may refer to: Water tunnel (physical infrastructure), a tunnel used to transport water, typically underground; Qanat water management system; Water tunnel (hydrodynamic), an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water, similar to a wind tunnel
In water or any other liquid, it is called a hydrodynamic force. Dynamic lift is distinguished from other kinds of lift in fluids. Aerostatic lift or buoyancy , in which an internal fluid is lighter than the surrounding fluid, does not require movement and is used by balloons, blimps, dirigibles, boats, and submarines.

The Biden administration on Wednesday announced nearly $200 million in federal infrastructure grants to upgrade tunnels that carry streams beneath roads but can be deadly to fish that get stuck ...
Submerged floating tunnels can be anchored to the seafloor (left) or suspended from a pontoon (right) A submerged floating tunnel (SFT), also known as submerged floating tube bridge (SFTB), suspended tunnel, or Archimedes bridge, is a proposed design for a tunnel that floats in water, supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes' principle).
A Delta water-delivery project — one tunnel or two — has been touted by Jerry Brown and Newsom’s teams as a way of correcting a fundamental problem with California’s delivery system that ...
