Regarding rivers, the Danube was navigable throughout its entire course in Yugoslavia, linking the ports of Belgrade, Novi Sad, and Vukovar with Central Europe and the Black sea. Long stretches of rivers Sava, Drava and Tisza were also navigable.
International Commission for the Protection of the Danube River
The commission became active in 1998. Since then, it has grown into one of the largest and most active international bodies of river basin management expertise in Europe. The commission deals not only with the Danube itself, but also with the whole Danube River Basin, which includes more than 300 tributaries and the ground water resources.
