Definitions
 

Tonne-kilometre: a unit of measurement that combines weight and distance. For example, transporting 2 tonnes (of goods in weight) across a 2-kilometre distance represents 4 tonne-kilometres.

Dry bulk: non-liquid goods that are not packed per piece in containers, on pallets or in boxes. They are poured unpacked and in large quantities (bulk) into the hold of a vessel. Examples include coal, iron ore, cereals, sand and gravel.

Remarks on quality
 

The traffic data are collected when issuing navigation licences or as part of the registration process when vessels go through locks.

In reality, the tonne-kilometres in the Flemish Region are slightly higher than the figures specified in this report. This is because there are a number of stretches of inland waterway where vessels are able to transport cargo without this being registered (under-reporting on the Zeeschelde and on tidal waterways).

Since 2017 data are provided by the Flemish Waterways (merger of Waterwegen & Zeekanaal with De Scheepvaart). Data before 2017 are the sum of data from Waterwegen & Zeekanaal and of Zeekanaal. This addition turned out to lead to very modest double counting and therefore an overestimation. These double countings are no longer present in the figures of the Flemish Waterways (since 2017).
