The Bec d'Ambès (French pronunciation:[bɛkdɑ̃bɛs], literally Beak of Ambès) is the point of confluence of the rivers Garonne and Dordogne, in the Gironde estuary. Situated 15 miles north of Bordeaux, it has an oil refinery which was destroyed by bombing during World War II, but rebuilt after the war. It is in the Ambès commune.
The Garonne (/ɡəˈrɒn,ɡæˈrɒn/gə-RON, garr-ON, French:[ɡaʁɔn]; Catalan, Basque and Occitan: Garona, Occitan pronunciation:[ɡaˈɾunɔ]; Latin: Garumnaor Garunna) is a river that flows in southwest France and northern Spain. It flows from the central Spanish Pyrenees to the Gironde estuary at the French port of Bordeaux – a length of 529 km (329 mi), of which 47 km (29 mi) is in Spain (Val d'Aran); the total length extends to 602 km (374 mi) if one includes the Gironde estuary between the river and the sea. Its basin area is 56,000 km (22,000 sq mi), which increases to 84,811 km (32,746 sq mi) if the Dordogne River, which flows from the east and joins the Garonne at Bec d'Ambès to form the Gironde estuary, is included.
