SADE took no notice and construction was completed in October 1959 in February 1960, SADE was authorised to start filling the basin. This led to new studies in which three experts separately told SADE that the entire side of Monte Toc was unstable and would be likely to collapse into the basin if the filling were completed. Ĭonstruction work started in 1957 but by 1959 shifts and fractures were noticed while building a new road on the side of Monte Toc. SADE stated that the geology of the gorge had been studied, including analysis of ancient landslides and that the mountain was believed to be sufficiently stable. In the 1950s, SADE's monopoly was confirmed by post-fascist governments, and it bought the land despite opposition by the communities of Erto and Casso in the valley, which was overcome with government and police support. Tens of kilometres of concrete pipes and pipe-bridges across valleys were planned. The dam and basin were intended to be at the centre of a complex water management system in which water would have been channeled from nearby valleys and artificial basins at higher levels. The dam wall had a volume of 360,000 cubic metres (13 million cubic feet) and held up to 168.7 million m 3 (5.96 billion cu ft) of water. ![]() ![]() Not until the confusion after Mussolini's fall during World War II was the project authorized, on 15 October 1943. The 'tallest dam in the world', across the Vajont Gorge, was conceived in the 1920s to harness the Piave, Mae and Boite rivers, to meet the growing demand for power generation and industrialization. The owner, Giuseppe Volpi di Misurata, had been Mussolini's Minister of Finances for several years. The dam was built by SADE, the electricity supply and distribution monopoly in north-eastern Italy. 3 The tests of the hydraulic model of the Vajont tank.Underestimating the size of the landslide, ENEL's attempt to safely control the landslide by lowering the lake's level came when disaster was almost imminent. They had disregarded numerous warnings, signs of danger and negative appraisals. This event occurred after ENEL and the Italian government concealed reports and dismissed evidence that Monte Toc, on the southern side of the basin, was geologically unstable. The dam remained almost intact and two thirds of the water was retained behind it. On 9 October 1963, during initial filling, a landslide caused a megatsunami in the lake in which 50,000,000 cubic metres (1.8 ×10 9 cu ft) of water overtopped the dam in a wave of 250 metres (820 ft), which brought massive flooding and destruction to the Piave Valley below, leading to the destruction of several villages and towns, causing between 1,900 and 2,500 estimated deaths. The engineer was Carlo Semenza (1893–1961). The dam was conceived in the 1920s and eventually built between 19 by Società Adriatica di Elettricità (SADE), at the time the electricity supply and distribution monopoly in northeastern Italy. It is in the valley of the Vajont River under Monte Toc, in the municipality of Erto e Casso, 100 kilometres (62 mi) north of Venice. It is one of the tallest dams in the world, with a height of 262 m (860 feet). The Vajont Dam (or Vaiont Dam) is a disused dam in northern Italy. The wall of water that overtopped the dam by 250 metres (820 ft) and destroyed this village and all nearby villages on 9 October 1963 would have obscured virtually all of the blue sky in this photo.
