Danube Cooperation

IHP Danube Cooperation Logo

In 1971, the hydrologists of 8 Danube Countries launched on a voluntary basis a regional hydrological cooperation aiming to produce consistent hydrological information about the whole Danube Catchment with an area of 817,000 km². 

Since 1987, this cooperation has been carried out in the framework of the International Hydrological Programme (IHP) of UNESCO, so far under the coordination of the IHP National Committees of Germany, Austria, Slovakia and Hungary.


The cooperation of the Danube countries within framework of the IHP of UNESCO is based on the one hand on project work and on the other on regular conferences. The aim of the conferences is to serve as a forum for discussion and exchange of views among the specialists involved. 

The Ist Conference was held in Budapest (Hungary) in 1961. The XXIVth Conference of the Danube Countries on Hydrological Forecasting and Hydrological Bases of Water Management took place in Bled (Slovenia) in 2008. The next Conference is to be convened in Budapest (Hungary) in 2011.

Expert Meetings

Since 1987, Working Group (WG) meetings of experts - representatives of the IHP UNESCO National Committees of the Danube Countries are scheduled on a yearly basis in one of the 18 member countries in order to coordinate the projects.
