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

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

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

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.

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 landing stage or small pier at which boats can dock or be moored.

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

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

A place where the ship can moor. In the case of a quay or jetty structure, it will include the section of the structure where labor, equipment and cargo move to and from the ship.

A protected water area to provide safe and suitable accommodation for ships for the transfer of cargo, refueling, repairs, etc

A sheltered place where the ship may receive or discharge cargo. It includes the harbor with its approach channels and anchorage places

a type of dock consisting of a rectangular basin dug into the shore of a body of water and provided with a removable enclosure wall or gate on the side toward the water, used for major repairs and overhaul of vessels

An artificial landing place for the loading and unloading of ships.

Any structure built into the sea but not parallel to the coastline and includes any stage, stair landing place, landing stage jetty, floating barge, and pontoon, any bridge or other works connected there with.

are wave with an extremely long period that mainly occur when there is a sudden large-scale sea floor movement usually associated severe, shallow focus earthquake

At places where the water depth is no more than about three times the equivalent deepwater wave height decreases rapidly of the wave height due to wave breaking shall be considered
