نهر يَانَة أو نهر بَطَلْيُوس (من اللاتينية: Fluminus Anae، وهو حاليًا بالإسبانية: Guadiana) ( /ˌɡwɑːdiˈɑːnə/, also الأمريكي /ɡwɑːdˈjɑːnə/, النطق الإسپاني: [ɡwaˈðjana], البرتغالية: [ɡwɐðiˈɐnɐ]), or Odiana هو أعرض نهر بشبه الجزيرة الأيبيرية، ينبع من وسط إسبانيا ويصب في المحيط الأطلسي على الحدود الإسبانية البرتغالية. يبلغ طوله 742 كم، ويفصل Extremadura and Andalusia (Spain) from Alentejo and Algarve (Portugal). The river's basin extends from the eastern portion of Extremadura to the southern provinces of the Algarve; the river and its tributaries flow from east to west, then south through Portugal to the border towns of Vila Real de Santo António (Portugal) and Ayamonte (Spain), where it flows into the Gulf of Cádiz. With a course that covers a distance of 829 kilometres (515 mi), it is the fourth-longest in the Iberian peninsula, and its hydrological basin extends over an area of approximately 68,000 square kilometres (26,000 sq mi) (the majority of which lies within Spain).

 أصل الاسم

The Guadiana drainage basin in the Iberian peninsula

The Romans referred to the river as the Flumen Anas, the "River of Ducks". During the Moorish occupation and settlement, the name was extended and referred to as Wadi Ana (wādī being the Arab term for "river"), later passed on to Portuguese and Spanish settlers as the Ouadiana, and later just Odiana. Since the 16th century, due to Castilian influences, the name has slowly evolved to take on the form Guadiana, a cognitive variation that developed from many Moorish-Arab river place-names using the prefix guad- (such as the rivers Guadalquivir, Guadalete, Guadalajara or Guadarrama).

The Guadiana flows east to west through Spain and south through Portugal, then forms the Spanish-Portuguese border; it flows into the Gulf of Cádiz, part of the Atlantic Ocean, between Vila Real de Santo António (Portugal) and Ayamonte (Spain). It is 818 kilometres (508 mi) long, of which 578 kilometres (359 mi) are within Spanish territory, 140 kilometres (87 mi) within Portugal, while 100 kilometres (62 mi) are shared between the two nations. About 82 percent, 55,444 square kilometres (21,407 sq mi), of its basin is in Spain, while about 17 percent, 11,560 square kilometres (4,460 sq mi) is in Portugal.

The exact source of the river in Castilla-La Mancha is disputed, but it is generally believed to spring in the Ojos del Guadiana, Villarrubia de los Ojos municipal term, Ciudad Real Province, Castile–La Mancha, about 608 metres (1,995 ft) in elevation.

There are over 30 dams on the river basin. The following are the dams on the Guadiana river itself:

• Alqueva Dam, the largest dam, located near Moura, in the Beja District, responsible for the largest reservoir in Western Europe. (There are several larger ones in Russia and Ukraine.) The Alqueva reservoir, occupies an area of 250 square kilometres (97 sq mi), with a capacity for 4,150 cubic hectometres (3,360,000 acre⋅ft).
