WAVE GENERATION. See GENERATION OF WAVES. 



WAVE, GRAVITY. See GRAVITY WAVE. 



WAVE GROUP. A series of waves in which the wave direction, wavelength, and 

 wave height vary only slightly. See also GROUP VELOCITY. 



WAVE HEIGHT. The vertical distance between a crest and the preceding 

 trough. See also SIGNIFICANT WAVE HEIGHT. (See Figure A-3.) 



WAVE HEIGHT COEFFICIENT. The ratio of the wave height at a selected point to 

 the deepwater wave height. The REFRACTOPM COEFFICIENT multiplied by the 

 shoaling factor. 



WAVE HINDCASTING. See HINDCASTING, WAVE. 



WAVE, IRROTATIONAL. See IRROTATIONAL WAVE. 



WAVE, MONOCHROMATIC. See MONOCHROMATIC WAVES. 



WAVE, OSCILLATORY. See OSCILLATORY WAVE. 



WAVE PERIOD. The time for a wave crest to traverse a distance equal to one 

 wavelength. The time for two successive wave crests to pass a fixed 

 point. See also SIGNIFICANT WAVE PERIOD. 



WAVE, PROGRESSIVE. See PROGRESSIVE WAVE. 



WAVE PROPAGATION. The transmission of waves through water. 



WAVE RAY. See ORTHOGONAL. 



WAVE, REFLECTED. That part of an incident wave that is returned seaward when 

 a wave impinges on a steep beach, barrier, or other reflecting surface. 



WAVE REFRACTION. See REFRACTION (of water waves). 



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.
