Santa Luzia Dam
Santa Luzia Dam (Portuguese: Barragem de Santa Luzia) is a concrete arch dam on the Unhais, a northern tributary of the Zêzere River, located in the municipality Pampilhosa da Serra, in Coimbra District, Portugal. The dam was constructed between 1930 and 1942[1] and was designed by André Coyne.[2]
Design
Santa Luzia Dam is a 76 m tall and 115 m long arch dam. The volume of the dam is 80.000 m³. The dam contains 2 crest spillways and one bottom outlet. At full reservoir level the reservoir of the dam (Portuguese: Albufeira da Barragem de Santa Luzia) has a surface area of 2.46 km² and its total capacity is 53.7 Mio m³.[1]
The concrete of the dam is affected by concrete swelling, caused by an alkali–silica reaction, that leads to tensions and cracks in the concrete.[3][4]
Power plant
The power plant is one of the smaller hydroelectric power stations in Portugal with a nameplate capacity of 32 MW. Its average annual generation is 55 Mio. kWh. The power station contains four Pelton turbine-generators.[1]
