The Aa is an 89 km long river in northern France. Its source is near the village Bourthes. It flows through the départements and cities of Pas-de-Calais: Saint-Omer and Nord: Gravelines.
The three main rivers in Germany are the Rhine (de|Rhein) (main tributaries including the Neckar, the Main and the Moselle (Mosel)); the Elbe (also drains into the North Sea); and, the Danube (Donau).
The rivers in this section are sorted south-west (Netherlands) to east (Danish border).
The Rhine, together with its tributaries the Aare and the Thur drain about two thirds of the water into the North Sea.
