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.
Sediment deposited inland of a beach by overwash processes.
Distance between the seabed and the still water level.
Elevation of still water level relative to some datum.
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.)
A ridge, deformation, or undulation of the surface of a liquid.
The ratio of wave speed to wind speed.
The speed of wave propagation.
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.
