Somme, river, France
river, c.150 mi (240 km) long, rising near Saint-Quentin, N France, and flowing generally NW past Amiens into the English Channel; connected by canal with the Scheldt and Oise rivers. Once an obstacle to east-west movement, the now reclaimed marshlands in the valley are noted for truck farming. During World War I heavy fighting took place there.
