  Vaiont Dam
Vaiont Dam, 262m high, on the Vaiont River, a tributary of the Piave River, in Venetia, NE Italy in the south-eastern part of the Dolomite Region of the Italian Alps, near Belluno, about 100 km north of Venice.
The dam, one of the highest in the world, was completed in 1961 and is used to generate HEP for the rapidly expanding northern cities of Milan, Turin and Modena.
The Vaiont reservoir disaster is a classic example of the consequences of the failure of engineers and geologists to understand the nature of the problem that they were trying to deal with.

 Vajont (Vaiont) lecture notes by Dave Petley
It appears that during the construction of the dam the chief engineer was concerned about the stability of the left bank of the dam, and a number of reports were compiled on this during 1958 and 1959, which identified a possible prehistoric slide on the right bank.
It was realised by the designers of the dam that the large mass of the left bank was inherently unstable.

The gravity dam uses the dead weight of the dam to resist the hydrostatic force of the water.
Construction of the dam was begun in 1993 and the entire project is expected to be complete in the year 2009.
The arch dam is used in tall rocky gorges and is curved facing the reservoir so as to transmit the major part of the water load to the abutments and to keep the masonry joints closed tight.

Vaiont Dam, 858 ft (262 m) high, on the Vaiont River, a tributary of the Piave River, in Venetia, NE Italy, near Belluno.
Vaiont Dam, one of the highest in the world, was completed in 1961 and is used to generate electricity.
After heavy rains in 1963, landslides into the Vaiont reservoir caused the stored water to spill over the dam, sweeping away the village of Longarone and flooding nearby hamlets; some 2,000 people drowned.

 Historical Events - The Vaiont Disaster, Northern Italy, 1963
The Vaiont disaster is particularly interesting as an example of a tsunami-like event in which human actions played a significant part, although it should be noted that the exact sequence of events is still the subject of litigation in Italy and some aspects are still not fully clear.
The Vaiont dam, at the time the tallest concrete arch dam in the world at some 260 m high, was built at the entrance to a very narrow and deep valley tributary to the Piave river valley in the Tyrolean Alps of NE Italy.
As the valley filled with water after completion of the dam in 1960, an ancient landslide on its upper southern side, adjacent to the dam, began to move again, in episodes of slow creeping movement.

The reservoir that occupied this valley prior to October of 1963 was contained by the Vaiont Dam.
Note that the dam held despite the tremendous stress that the slide and huge volume of water and debris exerted against it during the 1963 disaster.
Sediment of the slide is visible behind the dam.

 The Dam Site
Dam failures are of particular concern because the failure of a large dam has the potential to cause more death and destruction than the failure of any other man-made structure.
The Lower San Fernando Dam in California, USA did fail during an earthquake in 1971 which caused the fill in the dam wall to liquefy resulting in the collapse of the upstream part of the dam.
Dams are likely to exist, perhaps for hundreds of years, even after they are no longer required for their original purpose.

A dam must be impervious to water; leakage through or under a dam must be prevented to avoid excessive water loss and to prevent undermining of the structure itself.
A dam must also be constructed in such a way as to withstand the forces exerted upon it.
The most famous example is the disaster that occurred at the Vaiont Dam in the Italian Alps.

 BBC - h2g2 - Risk in an Industrial Society - Some Case Histories
The Vaiont Dam disaster is an excellent example of a failure of the engineers and geologists to understand the nature of the problems they are faced with.
Over the next few years, filling and lowering of the dam varied as the dam's engineers attempted to find the right water level where electricity could be generated and where the land would not slide.
An arch dam is a dam that is curves inwards from the downstream side, or is convex from that point.

The dam was constructed on the Yellow River in 1960.
Both dams were constructed on the basin of the Huai River, a tributary of the Yangtze River, in the 1950s.

They were surprised to find the dam still standing with a minimal amount of damage - but not much water was left in the reservoir.
On the right side of the dam, a huge mass of earth began a landslide that slid about 500m northwards at speeds up to 30 m/s (about 67 miles per hour).
In the interests of impartiality regarding such a sensitive issue, this entry has deliberately left out the precise details of the accident progression, whether they were determined by the UCC or the CBI with the Indian government, since they tend to contradict each other.

A wave estimated to be 100 m high spilled over the Vaiont dam and maintained a height of 70 m 1.6 km downstream obliterating the town of Longavone.
At the dam, the maximum surface elevation was predicted to 3.9-5.2 m depending on the pool level and landslide history.
For a high pool level of +601.5m, significant dam overtopping can be expected both as a consequence of the static increase of the reservoir level (estimated at approximately 3.2 m), but also from the long-periodic oscillations occurring in the reservoir.

On 9 October 1963, 300 million cubic metres of mountain slid into the lake behind what was then the tallest dam in the world, at Vaiont, 30km north of Venice.
The landslide displaced the water in the lake and created a 200 metre-high wave that overtopped the dam, raced over the town of Longarone and travelled both up and down the Piave valley at 80km per hour, wiping several communities off the map.
Surprisingly, the Vaiont barrage is still largely intact.

Edoardo Semenza is the geologist who discovered the Vaiont landslide in August, 1959, hypothesizing that it could move again once the reservoir had been filled.
La Storia del Vaiont raccontata dal geologo che ha scoperto la frana becomes, therefore, an indispensable resource upon which to base an objective judgement regarding the catastrophe as well as an important contribution to be certain that similar tragedies are not repeated.
His publications on Vaiont have provided a noteworthy contribution to two geotechnical engineers, American and Canadian, who, confronted with the feasibility of the construction of a huge dam on the Columbia River between the USA and Canada, discovered the enormous Downie landslide.
