Proposal of Dams in France (1/5) Barrage de Saint-Ferréol. Saint Ferréol Dam. Revel (Haute-Garonne), France (1675/1685). Located in La Montagne Noire, the Saint-Ferréol Dam is an earth dam equipped with a masonry retaining wall in the core. This dam is devoted to feed in water the Canal du Midi (registered at the UNESCO world Heritage) which links the city of Toulouse and the Mediterranean Sea. At construction, in 1675, the dam was 30m high. Later on, it was hightened until 36 m high in 1685. For around 200 years, this remarkable work was the highest earth dam in the world.

Le Tholonet (Bouches du Rhône), France (1854). The Zola dam, on the Infernet River, is located in Le Tholonet, South East of France. It was devoted to water supply of the city of Aix en Provence, as well as for industrial use by factories. The Zola dam is a masonry arch dam, 42m high, 68m long. At the time of construction, it was the highest in its category. It was considered for a long time as a model in the US basic book on dams by Wegmann (Editions from 1888 to 1927).

France (1866) This dam is built on the Furens River, which flows across the city of Saint-Etienne. Taking into account the rapid growth of this city, construction of this dam was decided in order to supply the city in water for citizens, to protect the city from floods, to help feeding factories in water. The Furens dam is a triangular masonry dam, 56m high, 100m long. At the time of construction, it was the highest dam in the world. Engineers: A. Graeff (1812-1884), E.

Proposal of Dams in France (2/5) Barrage d Eguzon. Eguzon Dam. (Indre), France (1926). This gravity-arch dam in concrete was built in order to produce electricity (Electricité de France). It is 61m high and 300 m long. At the time of construction, it was the most powerful dam in Europe. Engineer : C. Rabut Contractor : Enterprise Chagnaud www.structurea.de Picture : Jacques Mossot Barrage de Marèges. Marèges Dam. Ussel (Cantal) and Neuvic d Ussel (Corrèze), France (1934). This dam is built on the Dordogne River in order to produce electricity (Electricité de France). It is an arch dam in concrete, 90 m high and 198 m long. Apart this exceptional height at the time of construction, this dam shows considerable innovations in dam design and construction: vault involving a double curvature, abutment stabilized using 500 tons anchorages (monitoring using vibrating wires cells), construction of the foundations using an innovative cofferdam. Engineer : André Coyne Contractor: Entreprise Ballot www.industrie.gouv.fr/energie Barrage de l Aigle. Aigle Dam. Mauriac (Cantal), France (1947). This dam was built on the Dordogne river in order to produce electricity (Electricité de France). It is a combination of gravity and arch dam, in concrete, 92 m high and 290 m long. Its specific character is to be located in a very narrow gorge which obliged to develop a very innovative design. The whole structure integrates the vault dam, the power plant, and the 2 ski jumps spillways which are acting downstream-top of the power plant.

Proposals of Dams in France (3/5) Barrage de Génissiat. Génissiat Dam. Génissiat (Ain), France (1948). Génissiat dam is built on the Rhône river in order to produce electricity (Compagnie Nationale du Rhône, CNR). It is a gravity dam, in concrete, 104 m high and 165m long. The power plant is established just at the basis of the dam, using a flow of 750 m3/sec (maximum) for the 6 hydraulic turbines. Engineer : (CNR) P.

(Drôme-Ardèche), France (1952). This dam is built on the Rhône River in order to produce electricity (Compagnie Nationale du Rhône, CNR). It is a plant-dam in reinforced concrete, 32 m high, 248 m long. Construction of this dam needed 18 Million m3 of earthworks, a very exceptional volume in Europe at this time.

Proposal of Dams in France (4/5) Picture: Electricité de France Barrage de Serre Ponçon. Serre-Ponçon Dam. Gap (Hautes-Alpes), France (1960). This dam is built on the Durance River in order to produce electricity and to feed agriculture with water (EdF-Electricité de France). It is an earth dam, 129 m high, 600 m long, equipped with an impervious earth core, the highest earth dam in Europe. It was constructed using 2 technologies. For the dam itself, it deals with sophisticated compaction technologies transferred from the USA. The soil foundation comprises mainly permeable coarse materials (110 m deepness) which needed to be treated: innovative grouting was developed by the firm Solétanche for treatment of 60 m upper alluviums.
