List of tributaries of the Danube
The Danube is Europe's second-longest river. It starts in the Black Forest in Germany as two smaller rivers—the Brigach and the Breg—which join at Donaueschingen, and it is from here that it is known as the Danube, flowing generally eastwards for a distance of some , passing through several Central and Eastern European capitals, before emptying into the Black Sea via the Danube Delta in Romania.
Kamp
The Kamp is a 168 km long river in northern Austria, left tributary of the Danube. The source of the Kamp is on the border of Lower Austria and Upper Austria, near the town Liebenau, in the Mühlviertel. It flows generally east through Rappottenstein (where it receives its tributary "Kleine Kamp"), Zwettl, Krumau am Kamp and Gars am Kamp. The Kamp flows into the Danube near Grafenwörth, east of Krems.
