Malpasset Dam: Côte d'Azur France: breach was caused by a tectonic fault in the impermeable rock base, which had been inadequately surveyed. 423 deaths: 1959 Vajont Dam: Pordenone Italy: Overtopping due to landslide caused by instability of the rock around, with the evidence of the instability suppressed by the Government. 1,917 deaths: 1963 ...
The machinery hall, heating system, electricity supply, and sewage tunnels were under repair. [45] As the spillway works all the time, several methods of preventing the dam from icing were also under consideration. [46] The machinery hall and its heating system also underwent repairs. The repair work was performed continuously, 24 hours a day. [47]
Concorde variable air dam control ramps move to suit flight condition. An intake ramp is a rectangular, plate-like device within the air intake of a jet engine, designed to generate a number of shock waves to aid the inlet compression process at supersonic speeds. [1]
A combination of design and construction flaws, continuing to operate the dam when the primary system for gauging the water level was known to be inaccurate (gauge pipes had become detached), moving the "failsafe" secondary gauging system above the actual height of the dam to avoid false positives, and operating the dam in an unsafe manner by ...
The reservoir emptying through the failed Teton Dam on June 5, 1976 Ruins of the dam of Vega de Tera (Spain) after breaking in 1959. A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release.

The dam monitoring system checks the level of the water because this creates different pressures on the dam, also in relation to the air and water temperature. All these parameters are controlled and compared with the deformation and stress applied on the structure of the dam, measured with extensimeter, pendulum, reverse pendulum, piezometer, etc.
The fault line was thought to be inactive, but in February 2007, a study by the U.S. Army Corps of Engineers found evidence of at least one earthquake in the last 5,000 years, and therefore judged the fault line as active. With the new information about the fault line, the study said the dam was not likely to be in danger. [12]
Air dam may refer to various aerodynamic devices: Spoiler (car), on automobiles; Spoiler (aeronautics), on aircraft; Trailer skirt, on semi-trailers
