DAMS is a racing team from France, involved in many areas of motorsports. DAMS (an acronym for Driot-Arnoux Motorsport) was founded in 1988 by Jean-Paul Driot and former FerrariFormula 1 driver René Arnoux. Its headquartered in Le Mans, only 2 km from the Bugatti circuit.
Right from its inception, the French team entered the FIA International Formula 3000 Championship, which they won in 1990 with Erik Comas, 1992 with Olivier Panis and 1994 with Jean-Christophe Boullion. DAMS were one of many French teams that were part of the Elf young driver sponsorship program. They stayed in F3000 until 2002, the following year switching their effort to the Formula Renault V6 Eurocup, which they won that same year with Argentinian Jose Maria Lopez.
Aside from F3000, DAMS tried joining the Formula 1 World Championship in 1995, with a car developped by Reynard, but lack of funds prevented the team from advancing. Starting from 1997, Driot's team diversified into sports car racing, entering the FIA GT Championship in partnership with Panoz. Splitting up in the following year, DAMS ran a Lola-Judd B98/10 in the FIA Sports Racing World Cup, winning four races, as well as participating in the ALMS and Le Mans 24 Hours. In 2000 and 2001, DAMS associated themselves with General Motors, preparing the works Cadillac Northstar LMP prototypes for the ALMS, FIA SCC and Le Mans, but once again failed to get any results. DAMS helped the Michel Vaillant movie crew in the 24 hour race in 2002, and then switched their effort to the FIA GT. In 2003, they tried entering two Nissan 350Z, but once again funds prevented the French team from developing the Japanese car. In 2004, they teamed with Lamborghini and entered two Murciélago R-GT cars in the final rounds of the FIA GT Championship.
Rock-fill dams are embankments of loose rock with either a watertight upstream face of concrete slabs or timber or a watertight core.
Earth dams are constructed as a simple homogeneous embankment of well-compacted earth, sometimes with a watertight concretecore or upstream face, or sometimes with a hydraulic fill to produce a watertight core.
Single-arch dams are curved upstream and are usually constructed in narrow canyons or gorges where the rocky side walls are strong enough to withstand the tremendous lateral thrust of the dam that is caused by the pressure of the water.
Dams may also be constructed with roller-compacted concrete, in which thin layers of concrete are compacted as if they were earth layers; this produces a far stronger dam, without the need for full forms.
The Oroville Dam, located in California, the tallest in the United States, is 770 ft (235 m) high; the Rogun Dam, in Russia, the tallest in the world, is 1,100 ft (335 m) high.
