Wave Crest - Highest part of a wave or that part above stillwater level.
Wave Diffraction - See DIFFRACTION.
Wave Direction - Direction from which a wave approaches.
Wave Height - Vertical distance between a crest and the preceding trough.
Wavelength - Horizontal distance between similar points on two successive waves measured perpendicular to the
crest.
Wave Period - Time in which a wave crest traverses a distance equal to one wavelength. Time for two successive
wave crests to pass a fixed point.
Wave Refraction - See REFRACTION (of water waves).
Wave Steepness - Ratio of wave height to wavelength.
Wave Trough - Lowest part of a wave form between successive crests. Also, that part of a wave below that part
of a wave below Stillwater level.
Weep Hole - Hole through a solid revetment, bulkhead, or seawall for relieving pore pressure.
Wind Setup - See SETUP, WIND.
Windward - Direction from which wind is blowing.
Wind Waves - (1) Waves being formed and built up by wind. (2) Loosely, any waves generated by wind.
Wave Direction - Direction from which a wave approaches.
Wave Height - Vertical distance between a crest and the preceding trough.
Wavelenth - Horizontal distance between similar points on two successive waves measured perpendicular to the
crest.

wave crests to pass a fixed point.
Wave Refraction - See REFRACTION (of water waves).
Wave Steepness - Ratio of wave height to wavelength.
