River in France
The Drôme is a 57.9 km long river in Normandy.[1] Its source is on the border of the Manche and Calvados departments, at le Grand Cauville locality, near Saint-Martin-des-Besaces[2] and joins the Aure, left bank at Maisons, downstream of Bayeux in the Bessin region. It is a sub-affluent of the Vire.
Watershed
The watershed of the Drôme neighbours those of the Vire, Aure (east), Tortonne (NW) and Seulles (SE).
It is a narrow, northward basin. The longest of its affluents is the ruisseau du Vey (7.3 km),[1] which it joins at Cormolain.
