WASH LOAD
Part of the suspended load with particle sizes smaller than found in the bed; it is in near-permanent suspension and
transported without deposition; the amount of wash load transported through a reach does not depend on the transport
capacity of the flow; the load is expressed in mass or volume per unit of time.
WASHOVER
Sediment deposited inland of a beach by overwash processes.
WATER DEPTH
Distance between the seabed and the still water level.
WATER LEVEL
Elevation of still water level relative to some datum.
WATERLINE
A juncture of land and sea. This line migrates, changing with the tide or other fluctuation in the water level. Where
waves are present on the beach, this line is also known as the limit of backrush (approximately, the intersection of the land
with the still-water level.)
WAVE
A ridge, deformation, or undulation of the surface of a liquid.
WAVE AGE
The ratio of wave speed to wind speed.
WAVE CELERITY
The speed of wave propagation.
WAVE CLIMATE
The seasonal and annual distribution of wave height, period and direction.
WAVE CLIMATE ATLAS
Series of maps showing the variability of wave conditions over a long coastline.
WAVE CREST
See CREST OF WAVE.
WAVE CREST LENGTH
See CREST LENGTH, WAVE.
WAVE, CYCLOIDAL
See CYCLOIDAL WAVE.
WAVE DECAY
See DECAY OF WAVES.
WAVE DIRECTION
The direction from which a wave approaches.
WAVE DIRECTIONAL SPECTRUM
Distribution of wave energy as a function of wave frequency and direction.
