Tagus and Sado River Estuaries, Southwestern Portugal38.7N 9.1W
The Tagus River flows southward across Portugal from the top of this image to the city of Lisbon on the Tagus River Estuary below. Here, the estuary appears more brown in color to the north, where the river empties sediments into it.
Another estuary is visible to the southeast; this is formed by the Sado River near the city of Setúbal. Sediments are also visible here where the river flows into the estuary; however, the waters of the Sado River Estuary appear darker blue than those of the Tagus River Estuary.
