WAVE SETUP - See SETUP, WAVE. 



WAVE, SINUSOIDAL - An oscillatory wave having the form of a sinusoid. 



WAVE, SOLITARY - See SOLITARY WAVE 



WAVE SPECTRUM - In ocean wave studies, a graph, table, or mathematical 

 equation showing the distribution of wave energy as a function of 

 wave frequency. The spectrum may be based on observations or 

 theoretical considerations. Several forms of graphical display 

 are widely used. 



WAVE, STANDING - See STANDING WAVE. 



WAVE STEEPNESS - The ratio of the wave height to the wavelength. 



WAVE TRAIN - A series of waves from the same direction. 



WAVE OF TRANSLATION - A wave in which the water particles are permanently 

 displaced to a significant degree in the direction of wave travel. 

 Distinguished from an OSCILLATORY WAVE. 



WAVE, TROCHOIDAL - See TROCHOIDAL WAVE. 



WAVE TROUGH - The lowest part of a wave form between successive crests. 

 Also that part of a wave below Stillwater level. 



WAVE VARIABILITY - See VARIABILITY OF WAVES. 



WAVE VELOCITY - The speed at which an individual wave advances. 



WAVE, WIND - See WIND WAVES. 



WAVES, INTERNAL - See INTERNAL WAVES. 



WEIR JETTY - An updrift jetty with a low section or weir over which 



littoral drift moves into a predredged deposition basin which is 

 dredged periodically. 



WHARF - A structure built on the shore of a harbor, river, or canal, 

 so that vessels may lie alongside to receive and discharge cargo 

 and passengers. 



WHITECAP - On the crest of a wave, the white froth caused by wind. 



WIND CHOP - See CHOP. 



WIND, FOLLOWING - See FOLLOWING WIND. 



WIND, OFFSHORE - A wind blowing seaward from the land in a coastal area.
