River Duero

The River Duero (Durius-Latin, Douro-Portuguese) is the third longest and second largest river in the Iberian Peninsula at 765 km . Its source is at "Fuentes del Duero" in the Picos de Urbión in the Sístema Ibérico (Soria, near the border with Burgos and la Rioja). After cutting south-eastwards some 50km and passing through Soria, it turns west and slowly heads through the Northern Meseta , flowing through Almazán, Aranda de Duero, Tordesillas, and Zamora , and into Portugal, where after passing throrough a sparsely populated stretch of narrow canyons, finally empties into the Atlantic at Porto . The Duero watershed in Spain covers 78,954 square km, around 16% of the country, second to the Ebro. MORE TO COME

Among these are the Durius, which flows past Numantia and Serguntia....
