The existing pumped storage plant Coo in Trois-Ponts has two upper basins (Coo 1 & Coo 2), both being located on Mont de Brume, and a single lower reservoir located at an ancient river bend of the Amblève River. The plant was commissioned in two stages, Coo 1 (1969) and Coo 2 (1978).
Thakot Hydropower Project will exploit the difference in head of circa 180 m between the planned Patan Hydropower Project and the existing Tarbela Project. Various options are being studied to exploit this head. The options include a single dam and hydropower scheme and a cascade of lower dams and hydropower schemes.
The dam of the Laúca Hydropower Project is a roller compacted concrete (RCC) type with a maximum height of about 132 m and a crown length of about 1.1 km, creating a 11 km2 large reservoir with a storage capacity of about 5.5 x 109m3. The integrated spillway is equipped with three radial gates, each 15 m wide and 21 m high. The bottom outlet, with a 6.70 m height, 3.60 m width and a length of 115 m, is located in the middle of the dam.
The construction of the Capanda dam was initiated in 1982, but due to military conflicts the works stopped in the 1990s. After the resumption of the construction works the first units started going into operation in 2004. The power station contains four Francis Turbines with a capacity of 130 MW each. The dam is a roller compacted concrete (RCC) type with a maximum height of 110 m.
The original Naga Hammadi Barrage is located on the River Nile in Upper Egypt some 135 km north of the city of Luxor. It was commissioned in 1930 and is one of a series of structures to raise river levels and divert water to irrigation areas. After several years of planning, the construction of a new barrage began covering a sluiceway, a powerhouse and two navigation locks.
The Mujib Dam is located in the Wadi Al Mujib, south of Madaba and north of Al Karak. The Al Mujib drains toward the Dead Sea. The Mujib Dam is a composite dam, consisting of a RCC middle section and clay core rockfill (CCR) sections at both abutments. The water intake consists of draw-off works with intakes at three levels. The reservoir will be mainly used for irrigation purposes.
The construction of the Maguga Dam is the key element in the development of the irrigation potential of the Komati River in Swaziland and in South Africa. After review of a feasibility study of 1992 and other work done before 1996, one of 6 dam types had to be selected for the site. The dam types studied included an arch roller compacted concrete (RCC) dam, a gravity RCC dam, three rockfill dams (inclined clay core, asphalt core, concrete face) and a composite RCC rockfill option.
