The rivers shown on this map are among the most important waterways in Europe. They are drawn here in their full length, from source to sea, even though only a portion may be navigable. Nearly all of them flow to the north; only the Rhône/Saône flows south to the Mediterranean Sea and the Danube flows east to the Black Sea.
The green lines are approximations of the higher elevations that create the watersheds associated with these rivers. Waterway connections across these lines are made by summit canals; man-made canals rise through a series of locks to the summit then descend the other side through another series of locks.
This is especially important for those considering a trip between the English Channel/North Sea to the Mediterranean Sea; note that there is no direct river connection from north to south, and in fact the 19th-century canals across the center of France are restricted by locks 5.0 meters wide and stone-arch bridges with 3.5 meters clearance.
