the wave whose height and period are equal

to the mean height and period of all of the

waves in a wave group.

• highest wave

• highest one-tenth wave

• significant wave

• mean wave

average height of the higher high water over a 19-year period

• Mean Higher High Water (MHHW)

• Mean High Water (MHW)

• Mean Sea Level (MSL)

• Mean Lower Low Water (MLLW)

the average of the sea water surface for all stages of the tide over a 19-year period

• Mean Low Water (MWL)

• Mean High Water (MHW)

• Mean Sea Level (MSL)

• Mean Lower Low Water (MLLW)

the wave at a place where the water depth is at least one half of the wavelength; the wave parameters are expressed with those of the significant wave at this place

• highest wave

• deepwater wave

• significant wave

• mean wave

is the wave whose height and period are equal to the mean height and period of the highest one-tenth of the waves in a wave group. (H1/10, T1/10)

a berth structure for mooring the ship on the open sea; An isolated piled or gravity structure used either to maneuver a ship or to facilitate holding it in position at its berth.

• dolphin

A continuous structure built parallel to along the margin of the sea or alongside riverbanks, canals, or waterways where vessel may lie alongside to receive or discharge cargo, embark or disembark passengers or lie at rest

a navigable channel in a harbor, offshore etc; the usual course taken by vessels in such places.

• port

• harbor

• ocean port

• fairway

a period of approximately a few minutes to a few tens of minutes. It occurs when small fluctuations of the water level are generated by micro-scale variations of the atmospheric pressure by an air front or a low pressure in the outer sea, and the components of those oscillations whose period is the same as a natural period of the harbor are amplified through resonance
