Above the sea, but lying in a basin, skirts both banks of the river Semois which is crossed by two bridges.
SEMOIS (also spelt Semoy and SemoyS), a river of less than 120 m.
The province is well watered by the Ourthe, the Semois and the Sure.
The Belgian Ardennes may be said now to extend from the Meuse above Dinant on the west to the grand duchy of Luxemburg and Rhenish Prussia as far north as the Baraque de Michel on the east, and from a line drawn eastward from Dinant through Marche, Durbuy and Stavelot to the Hautes Fagnes on the north, to the French frontier roughly marked by the Semois valley in the south.
The numerous affluents of these rivers, such as the Lys, Dyle, Dender, Ourthe, Ambleve, Vesdre, Lesse and Semois, provide a system of waterways almost unique in Europe.
The Chiers, the Semois, the Lesse, the Sambre, the Ourthe and the Roer are its most important tributaries.
