Inland fisheries are any activity conducted to extract fish and other aquatic organisms from inland waters, plus aquaculture.

Movement of goods and/or passengers to and from inland ports connected by water routes which may be made navigable by one or more lock structures.

Inland valleys are the upper reaches of river systems, in which alluvial sedimentation processes are completely or almost absent. Inland valleys comprise the whole valley cross-section, i.e. valley bottoms, which may be submerged for part of the year, their hydromorphic fringes, and the contiguous upland slopes and crests extending over the area that contributes runoff and seepage to the valley bottom.

- The death of, or serious injury to, a person;
- The loss of a person from the vessel;
- The loss, presumed loss or abandonment of the vessel;
- Material damage to the vessel;
- The stranding or disabling of the vessel, or its involvement in a collision;
- Material damage to the inland waterway infrastructure external to the vessel that could seriously endanger the safety of the vessel or another vessel or individuals;
- Severe damage to the environment, or the potential for severe damage to the environment, brought about by the damage of the IWT vessel.

The movement of an IWT vessel from a specified point of origin to a specified point of destination.

A passenger disembarking from an IWT vessel after having been conveyed by it.
Note: A transfer from one IWT vessel to another is regarded as disembarkation before re-embarkation.

A passenger who boards an IWT vessel to be conveyed by it.
Note: A transfer from one IWT vessel to another is regarded as embarkation after disembarkation.

The combination of the place of embarkation and the place of disembarkation of passengers conveyed by inland waterways whichever itinerary is followed.

Vessel designed specifically to carry more than 12 fare-paying passengers by navigable inland waterways.

An area of land and water made up of such infrastructure and equipment so as to permit, principally, the reception of waterborne vessels, their loading and unloading, the storage of goods, the receipt and delivery of those goods and the embarkation and disembarkation of passengers, crew and other persons and any other infrastructure necessary for transport operators within the port area.

An inland waterways passenger vessel travelling primarily on rivers and intended to provide passengers with a full tourist experience. It accommodates all passengers with cabins for overnight stay and provides facilities for entertainment aboard. River cruise vessels stop at multiple ports along their way and may also operate on lakes and canals during the cruise.
Note: Vessels operating ferry services are excluded. Cargo-carrying vessels able to carry a very limited number of passengers with their own cabins are also excluded.

A statistical port consists of one or more ports, normally controlled by a single port authority or Harbour Master’s Office, able to record ship and cargo movements.

The movement of an IWT vessel on a given IWT network.
Note: When a vessel is being carried on another vehicle, only the movement of the carrying vehicle (active mode) is considered.

The movement of an IWT vessel within a national territory irrespective of the country in which the vessel is registered.

Inland waterway transport through a country between two places (a place of loading/embarkation and a place of unloading/disembarkation) both located in another country or in other countries provided that the whole journey within the country is by inland waterways and that there is no loading/embarkation and unloading/disembarkation in the transit country.

The movement of goods and/or passengers using IWT vessels, undertaken wholly or partly on navigable inland waterways.
Note: Bunkers and stores supplied to vessels in port are excluded. When an IWT vessel is being carried on another vehicle, only the movement of the carrying vehicle (active mode) is considered.

A floating craft designed for the carriage of goods, public transport of passengers or specially fitted out for a specific commercial duty which navigates predominantly in navigable inland waterways or in waters within, or closely adjacent to sheltered waters or areas where port regulations apply.
