Tributaries of the Guadiana

The Guadiana (Rio Guadiana) is the fourth largest river in the Iberian Peninsula, after the Tagus, the Douro and the Ebro.

It originates in the east of spain's Castile-La Mancha Autonomous Region and flows into the border of the Autonomous Region of Andalusia and the Portuguese Algarve in the Atlantic Ocean. It is 744 km long and forms part of the border between Spain and Portugal. Along the way she irrigates the Spanish cities of Mérida and Badajoz.

The Guadiana is navigable for shipping from Mértola in Portugal. The river is fed by a large number of small rivers that are mostly dry in the summer, which has to do with the lack of rain in this area and the great heat that prevails in the summer.

After all, it can get very hot here in the summer (in Amareleja in Portugal in 2003 it was recorded more than 40°C for 17 consecutive days, with an absolute maximum of 48.5°C at the beginning of August). Along with the Guadalquivir valley, it is even the hottest area in Europe. Despite the drought, it is also one of the most unspoilt and richest parts of the Iberian Peninsula and from Badajoz to the mouth at Vila Real de Santo António and Ayamonte there is a virtually contiguous and unique nature reserve.

However, the drought has also led to the construction of several dams for irrigation, which does not benefit nature (mainly quite rare birds). Show all -
