There are three facilities: 1) 32x0.6x1 m wave tank with a piston-type wavemaker, 2) 15x2x0.64 m recirculating type open-channel flume to study shallow coastal waters, and 3) 20x1x0.8 m tilting wind-water tunnel for air-water interface experiments. The facilities are mainly used for research within the institution. The DeFrees Hydraulics Laboratory houses three major facilities for generic studies of water waves, wave/current interaction, and wind waves. A 32x0.6x1 m wave tank with a piston-type wavemaker can create periodic and irregular waves for study of wave/structure interaction and waves over rippled beds. The Wide Meandering Wave-Current Flume is a recirculating channel that is 15x2x0.64 m. The Tilting Wind-Water Tunnel is also a recirculating basin, 20x1x0.8 m.

Four recirculating fluid (air and water) tunnels capable of investigating flows ranging from Reynolds numbers of 10^-3 to 10⁴; this range permits observation of fluid phenomena such as vortex streets, boundary layers, flow separation, surface waves, internal waves, jets, turbulent mixing, Stokes flow, and a variety of Reynolds number transitions. Gravity feed dye stream injectors, hydrogen bubble and pH indicator methods are used for flow visualization. A wind tunnel with a 3 ft by 3 ft working is used to understand the structural dynamics of plants forced by wind.

The main wind-wave-current interaction test section is 60 feet (18.29 meters) long, 4 feet (1.22 meters) high, and 3 feet (.91 meters) wide, filled to a water depth of 2.5 feet (.76 meters), with 1.5 feet (.45 meters) remaining for air flow. The facility is capable of winds up to 18 meters/sec, along with water current in either direction of about .5 knot (51 centimeters/sec) generated by pumping 100 gallons/sec through the facility's 16 inch pipes. Electronically controlled hydraulic units at both ends of the tank can generate any wave frequency or pattern up to 10 Hz. The computer control of wind, current, and hydraulic wave generating units can accurately repeat unsteady phenomena to allow its statistical study, as well as automate the facility operation. The water within the facility can be heated and maintained at warm temperatures, while the air flow can be cooled and humidity controlled at cool temperatures.The facility has an array of instruments including two channel backscatter LDV for water, two channel hot films and Pitot rakes for air, digital slope via color imaging, and IR video imaging. Joint research projects are invited.

The laboratory consists of a wave tank (18.3x2.5x1 m) with four hydraulic pistons for a quasi-directional wavemaker. In addition, the laboratory houses a TA Instruments rheometer and computing facilities for coastal research, including water waves over mud.

The Coastal & Hydraulics Laboratory (CHL) at the U.S. Army Corps of Engineers Engineer Research & Development Center in Vicksburg, Mississippi houses numerous physical modeling facilities. Wave and current flumes range in length from 30 to 60 m and in depth from 0.5 m to 1.5m. Flumes are equipped with wavemakers and current capabilities. Also located at CHL are large basin facilities, such as the Coastal Harbors Basins, the Inlets Research Basin, and the LA-Long Beach physical model. These basin models are large; for example the LA-Long Beach model covers 44,000 sq ft.

The Civil and Environmental Engineering Department at Old Dominion University in Norfolk, Virginia houses a few experimental facilities related to IMS. The Coastal Laboratory has a flume with dimensions 60x3x3 ft capable of generating random waves. The Hydraulics/Water Resources Laboratory has a channel flow experiment station, a rainfall-runoff-ground water hydrology apparatus, and basic hydraulics equipment to perform experiments relating to pipe flow and weirs, for example.

The Coastal Transportation Engineering Research & Education Center at the University of South Alabama in Mobile, Alabama has recently completed a 20x30x3 ft basin. It has a custom-built, programmable bulkhead wavemaker, capable of making waves of any shape. This facility will be used to study waves and their effect on beaches and built infrastructures such as roads, bridges, and breakwaters.

The Wide Meandering Wave-Current Flume is a recirculating channel that is 15x2x0.64 m. The Tilting Wind-Water Tunnel is also a recirculating basin, 20x1x0.8 m.

This laboratory is for physical and biological oceanographic research. The facilities include a wind wave tank, a stratified flow channel, a rotating table, a granular fluid basin, an oscillatory flow channel, a glass-wall wave channel, and a deep tank. There is access to both fresh and salt water. The facilities are available for researchers from other institutions.

This laboratory is for teaching and research in environmental fluid mechanics. The facilities include a small wave tank, a wind-wave facility, and a three-dimensional water-wave tank.

The Marine Mechanics Lab at U.C. Berkeley's Richmond Field Station holds a water basin 68x2.6x2 m. The facility has both low-speed and high-speed tow carriages, a computer-controlled wavemaker, and a hydraulic oscillator.

The main wind-wave-current interaction test section is 60 feet (18.29 meters) long, 4 feet (1.22 meters) high, and 3 feet (.91 meters) wide, filled to a water depth of 2.5 feet (.76 meters), with 1.5 feet (.45 meters) remaining for air flow.

There are two large-scale wave-wave basins specifically designed for long-wave (or shallow-water wave) research: 1) 27x49x2 m tsunami basin with multi-directional and programmable wavemaker, and 2) 104x3.7x4.6 m long-wave flume. Both are NSF-funded NEES facilities and open to external users for research, education, and outreach (shared facilities).

There are three facilities: 1) 20x20x1.1 m directional wave basin, 2) 33x0.6x0.76 m precision wave tank with recirculating current capability, and 3) 20x1x0.8 m sand beach wave tank. They are primarily used for research within the institution.

This is a commercial facility for testing of towing and seakeeping. The basin is 91.5x15.2x4.6 m. There is a test pit of 6.1x6.1x4.6 m for testing larger structures. A towing carriage permits the study of waves and currents on a structure. Typical tests concern ships and offshore platforms.

The Offshore Technology Research Center (OTRC) is located in College Station, Texas on the campus of Texas A&M University. The OTRC houses a large, deep-water basin designed primary to study offshore structures such as oil production platforms. The wave basin is 150x100x19 ft. The pit located in the center of the basin has a depth of 55 ft. A snake-type generator can produce random directional waves. Sixteen dynamically controlled fans can generate prescribed gusty wind conditions. A current generation system consisting of banks of submerged jets can generate sheared current profiles from any direction.

The wave tank supports research in the Department of Ocean Engineering. The facility is 30 m long, 3.5 m wide and 1.5 m deep. The wavemaker can create regular or irregular waves. Studies to date include sea keeping of ships, fishing trawl dynamics, and buoy dynamics.

The Centre for Marine Systems at Stevens Institute of Technology In Hoboken, New Jersey administers two laboratory facilities focusing on hydrodynamic research. The high speed towing tank is a 313x12 ft flume that can support water depths as high as 6 feet. It has a high-speed carriage capable of speeds from 0 to 100 feet per second with speed control of .01 feet per second. The oblique sea basin is 75x75 ft with water depths up to 5 ft. The facility has the capability to both tow model vessels at speeds up to 50 feet per second and generate regular or irregular waves.

There are three towing basins: shallow water, deep water, and high-speed basins. Those basins are used primarily for ship model studies.
