The Monte Novo dam ( Portuguese Barragem de Monte Novo ) is located in the Alentejo region of Portugal in the Évora district . It dams the Degebe , a right (western) tributary of the Guadiana to a reservoir (port. Albufeira da Barragem de Monte Novo ). The city of Évora is about ten kilometers northwest of the dam.

The project to build the dam began in 1976. The construction was completed in 1982. In addition to the drinking water supply, the dam is also used for irrigation.

Barrier structure

The barrier structure is a gravity dam with a height of 30 m above the foundation level (28 m above the river bed). The top of the wall lies at a height of 199 m above sea level . The length of the top of the wall is 160 m. The volume of the dam is 32,270 m³.

The dam wall has both a bottom outlet and a flood relief . A maximum of 11.7 m³ / s can be discharged via the bottom outlet, and a maximum of 609 m³ / s via the flood discharge. The design flood is 980 m³ / s; the probability of this event occurring has been determined to be once in 500 years.

Reservoir

At the normal storage target of 196 m (maximum 196.8 m at high water), the reservoir extends over an area of ​​around 2.77 km² and holds 15.28 million m³ of water - of which 14.78 million m³ can be used.
