13-445: It was first conceived in the 1950s to help replace nature groundwater resources for the town of Esch-sur-Sûre. Using an André Coyne design, the dam was constructed between 1956 and 1957 and the power station was commissioned in 1963. The reservoir has been drained twice during the dam's life; once in 1969 to install a new fixed water intake and again in 1991 to install and adjustable-arm intake which mitigate issues with algae growth in

26-420: A 50-meter-high (160 ft) wall of water that reached the nearby town of Fréjus , killing 423 people. It was said that Coyne was deeply affected by the dam's failure, and immediately blamed himself, claiming he was solely responsible. Indeed, Coyne did not implement the advice of Georges Corroy, a geologist, to build the dam 650 ft upstream, nor did he adapt the spillway gate to the flood flow. He died half

39-402: A surface area of 3.5 km (1.4 sq mi) and is 19 km (12 mi) long. It is 43 m (141 ft) at it deepest point and the normal elevation is 322 m (1,056 ft). The power station at the base of the dam contains two 5.5 MW Francis turbine -generators for a total installed capacity of 11 MW. The power station generates an average of 16 GWh annually. Downstream of

52-428: A year later. A study later found that the design of the dam was probably not the reason for its failure. Other factors were blamed instead, including the location of the dam, the stability of the rock material, the fact that a geological fault was found on the site, and heavy rain that had raised the water level by 15 feet that year. Also, intense mining for a new highway nearby downstream is suspected to have weakened

65-912: The Grandval and Roselend Dams . Abroad he designed the Kariba Dam on the Zimbabwe - Zambia border, the Daniel-Johnson Dam in Quebec and the Santa Luzia Dam in Portugal. Coyne also designed the Malpasset Dam in Southern France. Nearly immediately after construction was completed on the dam, cracks were noticed at the base. A few years later, on 2 December 1959, the dam abruptly broke and collapsed, releasing

78-1063: The Kariba Dam along the Zambia/Zimbabwe border was completed and the Malpasset Dam in France, which was completed in 1954, had a tragic failure. In the same year work was complete on two reactors at the Marcoule Nuclear Site in France along with the Yaté Dam in New Caledonia. In 1960, the Serre-Ponçon Dam was completed and André Coyne died. Two years later ACJB became Coyne et Bellier. They continued to design dams that were completed to include their 100th dam, Jatiluhur Dam in Indonesia, Daniel-Johnson Dam in Canada (1968) and Tour Aurore office building in France (1970). In 1976, Electrobel became

91-612: The Americas, and Africa. The company was created by André Coyne and is a subsidiary of Tractebel, now part of Engie . The company was established by André Coyne in 1947 as Engineering Consultancy André Coyne et Jean Bellier (ACJB). Of the many projects the company designed, the Tignes Dam in France which was completed in 1952 which was followed by the Bin el Ouidane Dam in Morocco in 1953. In 1959,

104-723: The chief engineer of dams in the Upper Dordogne River. While in that position, he designed the Marèges Dam which incorporated several innovative advancements in dam design (a.o., a spillway of the ski jumping ramp type). In 1935 he became the head of France's Large Dam Engineering Department and between 1945 and 1953 he served as President of the International Commission on Large Dams . In 1947 he departed civil service and started his own consulting firm, Coyne et Bellier . Other dams he later designed in France include

117-726: The dam site. The company that André Coyne started is still operating under the name Coyne et Bellier . This French engineer or inventor biographical article is a stub . You can help Misplaced Pages by expanding it . Coyne et Bellier Coyne et Bellier is a global consulting and engineering firm based in Gennevilliers , France . They specialize in infrastructure projects such as dams, nuclear and hydroelectric power plants, roads, tunnels and other below-surface facilities. The company also carries out environmental and social impact assessment . They operate out of 43 offices in Asia, Europe,

130-408: The dam there are three weirs fitted with Kaplan turbines with a total installed capacity of 550 kW. The dam also provides for flood control but has no spillway . Currently, two bottom outlets with a 450 m/s (16,000 cu ft/s) discharge capacity pass floods through the reservoir. Floods in the 1990s highlighted the need for a spillway at the dam. A design for a chute spillway on

143-468: The left abutment of the dam have been drafted but not implemented. Andr%C3%A9 Coyne André Coyne (10 February 1891, Paris – 21 July 1960, Neuilly-sur-Seine ) was a French civil engineer who designed 70 dams in 14 countries. He received his education at École Polytechnique and its School of Civil Engineering afterwards. He worked on the Plougastel Bridge and in 1928 was appointed as

156-688: The primary shareholder of the company. They completed El Saada Dam , their 150th, in Algeria in 1978. Electrobel merged with Tractionnel in 1987 to form Tractebel. Tricastin Nuclear Power Plant in France was completed in 1980 and the Grande Arche , also in France in 1989. When the Aoulouz Dam in Morocco was completed in 1990, it marked their 200th dam designed. Birecik Dam in Turkey was completed in 2000 and

169-478: The reservoir. The Esch-sur-Sûre is an arch dam with a height of 50 m (160 ft) and length of 170 m (560 ft). It is 1.5 m (4.9 ft) wide at its crest and 4.5 m (15 ft) wide at its base. The dam sits at the head of a 428 km (165 sq mi) catchment area and creates the Upper Sûre Lake which has a total volume of 59,000,000 m (48,000 acre⋅ft). The lake has
