Danube River
The Danube River basin and its drainage network.
The Danube River is geographically divided into three distinct sections based on its physiography:
- Upper Course: This section stretches from the river's source in the Black Forest mountains of Germany to the gorge known as the Hungarian Gates, located in the Austrian Alps and the Western Carpathian Mountains.
- Middle Course: This segment runs from the Hungarian Gates Gorge to the Iron Gate in the Southern Romanian Carpathians.
- Lower Course: This final section flows from the Iron Gate to the river's deltalike estuary at the Black Sea.1
