The Ruhr is a river in western Germany (North Rhine-Westphalia), a right tributary (east-side) of the Rhine. Its total length is 219 km (136 mi), its average discharge is 79 m³/s (cubic metres per second) at Mülheim near its mouth.


As one of the most attractive rivers in Germany, the Moselle is the second longest tributary of the Rhine (544km). The river has its source in France and flows through the Vosges and Lorraine. It then becomes a border river between Luxembourg and Germany. It flows into the Rhine near Koblenz, after which the Moselle flows through the Saarland and Rhineland-Palatinate.
