The Veiros dam ( Portuguese Barragem de Veiros ) is located in the Alentejo region of Portugal in the Évora district . It dams the Ana Loura to a reservoir. The center of the municipality of Veiros is about 200 m north of the dam.
The project to build the dam started in 2008. The construction was completed in 2012. The dam is used for irrigation. It is owned by the DGADR .
Barrier structure
The barrier structure is a dam with a height of 32.5 m above the foundation level (28.14 m above the river bed). The top of the dam is at a height of 272.50 m above sea level . The length of the dam crest is 150 m and its width 8 m. The volume of the dam is 201,550 m³.
The dam has both a bottom outlet and a flood relief . A maximum of 2.8 m³ / s can be discharged via the bottom outlet, and a maximum of 494 (or 298) m³ / s via the flood discharge. The design flood is 406 m³ / s; the probability of this event occurring has been determined to be once in 5,000 years.
Reservoir
With the normal storage target of 269 m (maximum 271.10 m at high water), the reservoir extends over an area of around 1.42 km² and holds 10.3 million m³ of water - of which 8.8 million m³ can be used. The minimum storage target is 256.70 m.
