"the Upper Rhine, it forms the southern part of the border between Germany and France" http://en.wikipedia.org/wiki/Rhine_river#Germany_and_France

Really? I thought it was France and the netherlands.

I think it is pretty rare for two countries to have a common Western border... The Rhine is part of Switzerland's eastern border with Liechtenstein and then Austria (you could also say western border of Liechtenstein and Austria with Switzerland). Later it becomes the southern border of Germany with Switzerland, then Germany's western border with France. For a few kilometers it flows along the Dutch-German border.

france and germany... personally, this is common knowledge to me... but then again, just about 80% of californians don't know where the pacific ocean is.

I believe that it is Germany and France.

Sounds like a homework question to me. Look it up on a map of Europe.

... with Duchacek (1984, 1986), we will call this form of cross ... are located in Western Europe. One is the Upper Rhine Valley with the neighbouring states of France ...

I think it is pretty rare for two countries to have a common Western border... Hm, haven't I seen this question before?

1) The Rhine river is a part of the eastern border of France and of the western border of Germany, in the approximative region between Basel (Switzerland) and Karlsruhe (Germany). Before this, it makes about the border between Germany in the North and Switzerland in the South. And before the Bodensee (lake of Constance), it makes - as the "Alpenrhein/Alpine Rhine" river the eastern/western border between Switzerland on the West and Austria, and before, Lichtenstein on the East. So there would be three answers, starting from the Rhine spring, if you also consider the "Alpine Rhine": - Switzerland / Lichtenstein - Switzerland / Austria - France / Germany Please check on this map: http://upload.wikimedia.org/wikipedia/commons/4/47/Rhein-Karte.png 2) "From Reichenau, the Rhine flows north as the Alpenrhein passing Chur and forming the frontier with Liechtenstein and then Austria, and then emptying into Lake Constance. Emerging from Lake Constance, flowing west as the Hochrhein it passes the Rhine Falls and is joined by the Aare river which more than doubles its water discharge to an average of nearly 1,000 cubic meters per second. It forms the boundary with Germany until it turns north at the so-called Rhine knee at Basel." "Past Basel, as the Upper Rhine, it forms the southern part of the border between Germany and France in a wide valley, before entering Germany exclusively at Rheinstetten, near Karlsruhe." "The Rhine then turns west and enters the Netherlands, where together with the rivers Meuse and Scheldt it forms the extensive Rhine-Meuse-Scheldt delta, one of the larger river deltas in western Europe."
