River basin district

from Wikipedia, the free encyclopedia

The river basin district ( RGE ) is a term from the EU Water Framework Directive . The catchment areas of the rivers are assigned to the states, and small areas are grouped into systematic groups.


In Article 2 of the Directive, the term river basin district is defined as follows:

"[...] a land or marine area defined as the main unit for the management of catchment areas, which consists of one or more neighboring catchment areas and the groundwater and coastal waters assigned to them"

- Directive 2000/60 / EC, Article 2, definition 15

The river basin units are the common and national planning areas for the implementation of the WFD in which water management plans are drawn up.


  • In the case of large river systems , the river basin district is the hydrological catchment area ( surface + groundwater bodies ) plus the coastal waters near the mouth .
  • In coastal landscapes with many small river systems, the catchment areas of the sea tributaries of a coastal section and the coastal waters into which they flow can be combined into a river basin unit for administrative purposes or added to the river basin unit of the nearest river . A good example is the river basin district Schlei / Trave , named after a bay and the largest of the small rivers , which includes all the sea tributaries of the Schleswig-Holstein Baltic Sea coast and with the catchment area of ​​the Stepenitz extends as far as Mecklenburg-Western Pomerania .
  • Since the river basin districts were defined without taking national borders into account, there are national river basin districts if all the bodies of water concerned are assigned to one and the same nation state, and international river basin districts if several European nation states are affected. In this case, all planning must also take place in the context of the states concerned.

Austria has a share in the river basin units (river catchment areas) Danube (80,593 km², 96% of the Austrian territory), Rhine (2.8%, in Vorarlberg) A6 and Elbe (1.1%, small area in the Mühlviertel and Waldviertel).

The river basin units (planning areas) of the National Water  Management Plan (NPG) are:
