Danube River Connections to Other Rivers

The Danube links to other rivers via canals and tributaries:

• Canals: Danube–Oder Canal (to Oder River, Poland); Danube–Main Canal (to Main River, Germany → Rhine–Main–Danube Canal to North Sea).
• Major Tributaries: Inn, Drava, Sava, Tisza, Prut—these feed the Danube and connect its basin across Central/Eastern Europe.

This network enables navigation from the Black Sea to the North Sea.
