context_page_description: The Somme is a river in Picardy, northern France. The name Somme comes from a Celtic word meaning "tranquility". The department Somme was named after this river.
  The river is 245 km long, from its source in the high ground of the former Forest of Arrouaise at Fonsomme near Saint-Quentin, to the Bay of the Somme, in the English Channel. It lies in the geological syncline which also forms the Solent. This gives it a fairly constant and gentle gradient where several fluvial terraces have been identified.
context_section_description: Mean flow rates monthly and daily at Péronne (m³/s). Catchment area 1,294 km² (500 sq mi).
