Sediments in the Gironde Estuary, France45.3N 0.7W
The Gironde Estuary, on the western coast of France, appears tan due to sediments flowing into it from the Dordogne and Garonne Rivers.
The Gironde Estuary is the primary body of water the impacts the Bordeaux Region of France. It is more than 80 kilometers in length and is formed where the Garonne River and the Dordogne River converge near Bourg.
The Garonne River extends 360 miles and is formed to the Northeast in the Central Mountains of France. The Dordogne is nearly as long as the Garonne. It runs east and then south all the way to the Pyrenees Mountains that divide France and Spain.
Much of the land around the estuary is known for wine production, including the Medoc, located along the middle of the southern bank of the Gironde. Upstream from the Gironde Estuary along the Garonne River are the wine regions of Pomerol and Saint Emilion.
