DOURO (Span. Duero, See also:Port. Douro, anc. Durius)  , a See also:river of the Iberian See also:Peninsula . The See also:Douro rises See also:south of the Sierra de la Demanda, in the See also:Pico de Urbion, an isolated See also:mountain See also:mass 7389 ft. high . It describes a wide See also:curve eastwards past See also:Soria, then flows westward across the Castilian table-See also:land, passing south of See also:Valladolid, with See also:Toro and See also:Zamora on its right See also:bank; then from a point 3 M . E. of Paradella to See also:Barca d'See also:Alva it flows south-See also:west and forms the frontier between See also:Spain and See also:Portugal for 65 m . It crosses Portugal in a See also:westerly direction through a narrow and tortuous See also:bed, and enters the See also:Atlantic 3 M. below See also:Oporto at Sao Joao da Foz . The length of the Douro, which is greater than that of any other Iberian river except the See also:Tagus and See also:Guadiana, is probably about 485. m.; but competent authorities differ widely in their estimates, the extremes given being 420 and 507 M . In Spain the Douro receives from the right the See also:rivers Pisuerga, Valderaduey and Esla, and from the See also:left several small streams which drain the Sierra Guadarrama, besides the more important rivers Adaja, Tormes and Yeltes; in Portugal it receives the Agueda, Coa and'Paiva from the left, and the Sabor, Tim. and Tamega from the right . The See also:area drained by the Douro and its tributaries is upwards of 37,500 sq. m., and includes the greater See also:part of the vast See also:plateau of Old See also:Castile, between the See also:water-sheds of the Cantabrian Mountains, on the See also:north, and the Guadarrama,eGredos, Gata and Estrella ranges; on the south . The See also:lower stream is beset with numerous rapids, called pontos, and is subject to See also:swift and violent inundations . On this See also:account See also:navigation is attended with difficulties and risks between its mouth and Barca d'Alva; but a railway, See also:running for the most part along the right bank, skirts the river during the greater part of its course through Portugal . The mouth of the river is partly blocked by a sandy See also:bar; only See also:ships of See also:light See also:draught can enter, while those of greater See also:burden are accommodated at the See also:harbour of See also:Leixoes, an artificial See also:basin constructed about 3 M . N .

On its way through Portugal the Douro traverses the Paiz do Vinho, one of the richest See also:

wine-producing territories in the See also:world; large quantities of wine are conveyed to Oporto, in sailing boats . The Douro yields an abundance of See also:fish, especially See also:trout, See also:shad and lampreys .
