History

Construction on the laboratory began in 1972. In 1973, the facility opened with the wave flume used to simulate the ocean waves. The circular wave and rectangular wave basins were both finished in 1990. That year the lab received a grant from the United States’ Office of Naval Research

 for $8.6 million to examine wave structures, which helped to pay for the two new wave basins.

In 2001, the Wave Research Laboratory was awarded a $4.8 million grant to study tsunamis by the National Science Foundation. The remodeled portion of the facility, the Tsunami Wave Basin, was completed in 2003. In 2007, the foundation granted the laboratory $1.1 million to study storm surges and other waves related to hurricanes.

Facility

The first wave research equipment was the wave
Wave
In physics, a wave is a disturbance that travels through space and time, accompanied by the transfer of energy.Waves travel and the wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass...

 flume
Flume
A flume is an open artificial water channel, in the form of a gravity chute, that leads water from a diversion dam or weir completely aside a natural flow. Often, the flume is an elevated box structure that follows the natural contours of the land. These have been extensively used in hydraulic...

. It is 360 feet (109.7 m) long, 12 feet (3.7 m) wide, and 15 feet (4.6 m) deep. It is used to simulate the waves of the ocean, and creates 5 feet (1.5 m) waves with currents strong enough to surf on. The wave flume holds up to 350,000 gallons of water. It can create both regular and irregular waves at intervals as short as .5 seconds apart. Research is mainly on the effect of waves on structures such as breakers.

A circular basin was added in 1990 to research the movement of sediment along beaches, among other research topics. It is also used to study ocean current
Ocean current
An ocean current is a continuous, directed movement of ocean water generated by the forces acting upon this mean flow, such as breaking waves, wind, Coriolis effect, cabbeling, temperature and salinity differences and tides caused by the gravitational pull of the Moon and the Sun...

s. The Circular Wave Basin can create waves up to 2 foot (0.6096 m) in height in the 5 feet (1.5 m) deep structure that is 50 feet (15.2 m) in diameter.

The rectangular basin has 30 wave generators that can be used to simulate a storm in the controlled environment of the lab. In 2001, it was expanded to a size of 87 feet (26.5 m) by 160 feet (48.8 m) with a depth of 6.5 feet (2 m) to facilitate tsunami research. Research includes the effects of a tsunami on coastal population centers and possible survival options. The Tsunami Wave Basin was the first in the world dedicated to tsunami research, and is the largest and most advanced facility in the world. Additionally, the tsunami laboratory has a variety of above and below the water cameras, wave gauges, and microphones. They also operate a Tsunami Experimental Databank that allows other researchers to access video and data over the internet.
