Name Sub-unit
Short Description Spatial data for river basin district sub-units
Definition River Basin District sub-unit:
Spatial unit created for management, monitoring or reporting purposes, in a river basin district (RBD) larger than 50000 square kilometre. Large RBDs should be divided into comparable sub-units with an area between 5000 and 50000 square kilometre. The sub-units can be created using river basins (if more than one river basin exists in the RBD) or sub-basins, for example. If the RBD area is less then 50000 square kilometre, the RBD itself can be used as a sub-unit.

Sub-basin:
The area of land from which all surface run-off flows through a series of streams, rivers and, possibly, lakes to a particular point in a water course (normally a lake or a river confluence).
Methodology for obtaining data For non-EU countries and in the absence of officially designated sub-units, sub-basins can be used for EIONET reporting purposes.
