Ardre

The Ardre is a fifth order river in France which flows into the Vesle (left tributary) thence into the Aisne, Oise and Seine.

Geography

The river lies to the west of Reims and flows on bearing of about 310° from the Parc Régional de la Montagne de Reims to enter the Vesle at Fismes.

It rises at an altitude of about 270 metres and descends over a course of 39 kilometres, to about 80m in Fismes. It is crossed by the Paris to Reims motorway, A4/E50 about halfway along the river's length.

It's geology is comparable with that of the lower Thames valley and south Hampshire. Though the chalk of the Champagne plateau is not far away, towards Reims, the immediate surroundings are of middle Eocene but the river has cut down into lower Eocene clay deposits like those at Chichester. Consequently, the landscape is much more wooded than that typical of Champagne.

Hydrology

The Ardre's flow was observed during a period of 37 years (1969–2005), at Fismes, in the département of Marne situated at its confluence with the Vesle. The catchment area of the river is 297 km² (115 sq mi).
