Guadiana (río)

The Guadiana is a major river in the Iberian Peninsula, flowing about 744 kilometers (462 miles) through Spain and Portugal. It originates in Spain’s hills and winds across southwestern Spain into Portugal, where it runs along the border before emptying into the Atlantic Ocean. This river supports agriculture, provides drinking water, and sustains ecosystems and cities along its course. The Guadiana also features a unique ecological basin and an important floodplain, making it vital for regional biodiversity and local economies. Its basin covers a large area, making it a significant natural resource for both countries.
