Then came A: the oil crisis and revelation we were in a fossil fuel addicted society, with all pollution and greehouse effect soon to come.... B: The 1976 Seveso dioxine poison cloud over north Italy, next door.....

A French disaster you would probably find interesting is the November 2015 TGV crash in Eckwersheim, Alsace. It happened during deliberate overspeed tests on a new high-speed line and claimed 14 lives (iirc). It was totally ignored by the media because the day before, 130 people had been murdered by ISIS in the Paris attacks. And yet, 14 people died due to violation of basic safety measures, or to be precise a total lack of them during the test. It's a huge scandal for the national company (the SNCF) and I hope there will be a trial.

The driver basically asked his assistant when he had to brake, and the assistant was like "oh around here, don't worry we're good" before panicking and braking in extremis. That was the day before the accident. It's unbelievable that they didn't have a very precise planning and instructions about what to do. When you're going at 350 km/h you can't make mistakes. If you brake 5 minutes too late you've already lost several kilometers. Also, overspeed tests weren't even needed in 2016 because we can do the same but better with computers. They were a thing back in 1981 when modelling was not possible yet and you actually needed to push the train to its limits to know what happens.

I visited the site a few years ago. The size of the dam is impressive, and so is the size of the debris.. i passed three-storeys high concrete blocks on my way there. I was able to to crawl through the metal pipe at the bottom, through the valve which was left wide open, forever trying to lower the water level. But the most incredible sight is the gigantic hole in the ground under the left half of the dam (which is still standing). Water managed to dig under the dam and dug a huge hole in the ground, through which you can see the other side of the dam. You could walk under the dam if the hole wasn't filled with water.

I was 15 in 1959 and since then I had always thought of the name as Malplasset (‘Mal placè’) but in fact the actual name is Malpasset which in old French means "Bad passage”. What is said in the video is absolutely correct, but there are more details that can be found in a Wikipedia article (in French) titled : “Barrage de Malpasset”. You can attempt to translate the text with “Googke Trad", which will give you - in spite of mistranslations of the technical terms - a surprisingly good feel for the gist of the article. As I understand from this Wikipedia article, there has been three main causes for the catastrophe : •-Cause #1 (correctly stated in the video): Insufficient geotechnical study. The only geologist consulted (at the preliminary studies level) advised the construction of a gravity dam further upstream. Coyne & Bellier were the specialists of arch dams, and what the geologist was recommending was the old gravity dam building technique (which had been considered for this same location in the 1880’s). So the geologist was considered “an old beard”; he was not listened to and was no longer consulted. The geotechnical "study" was reduced to a geological field survey and some mechanical soundings; As shall be seen below, there was almost no site geotechnical monitoring. Unfortunately for Coyne & Bellier (and for the inhabitants of Fréjus), the soil at the location was made of Gneiss, considered impermeable but which was in fact fractured. Moreover the bedding of schistosity of this Gneiss was parallel to the direction of the vault. A concrete pillar was built as an abutment for the vault, but the bonding injections were sketchy and there was no concrete shroud (‘voile’) in front of the foundations, because the Gneiss was considered to be impermeable - which it was not, due to its fractured state. •-Cause # 2: Lack of on-site geotechnical monitoring. The video correctly states that the filling of the dam took years after completion of the building phase, but does not give the reason. A company operating the Madeleine fluorite mine and the Garrot mine, both located upstream, had been dragging out its expropriation procedure, forcing the operator of the dam to let the water level low (using the drain valve of the dam) so that the galleries of the mines would not be flooded until the expropriation was complete. Thus the dam could not be flooded for five years after its construction, and the control of its behavior during the commissioning phase - the classic periodic strain measurements, essential for any dam - could not, in the case of Malpasset, be rigorously carried out and carefully interpreted as they should have been. •-Cause #3: Letting the water level of the dam exceed the safety limit. This is correctly said in the video, but sketchily, so that the conundrum of the dam operator is difficult to understand. Due to abundant rains on Dec. 1-2 1959, provoking a very violent flood, the level of the reservoir, which was about ten meters below the crest of the dam, did rise very quickly, by 4 m in 24 hours; Moreover there were seeps downstream of the structure becoming real springs as the water rose. It would therefore have been necessary to open the drain valve wide to lower the water level in the dam. But 1 km downstream there was the construction site for the bridge over the Reyran on the Esterel-Côte d'Azur motorway path. The spillage of water would have flooded the machinery & equipment of the construction site and could even have damaged the bridge structure which was already under construction. It was therefore decided at first not to open the valve, in spite of the risk involved for the dam. André Ferro, keeper of the dam, did not receive the order to open the drain valve until December 2 at 6 p.m., a time when the water was ready to overflow, its level having risen far above the level of service and even above the design safety level of the dam. After the catastrophe, there was a judicial inquiry and a long controversy on the responsibilities, the geologists contending that they had not been listened to and the designers & builders contending that the geological science was not advanced enough to prevent the failure of the dam. It would seem that the responsibilities were shared. The “Institut de géologie de Nancy” was established in 1913 and its successor ”École supérieure de géologie”, est. 1944, had already developed knowledge and methods which were successfully used on other sites. The absence of meaningful dialogue between the geologist and the designers & builders seems the main feature here: The former did not adapt to the new arch-dam design concept and did not forcefully ask for the means of an on-site investigation leading to specific evaluations and recommendations; The latters knew how important its was to ascertain that the dam extremities would rest on abutments strong enough to resist extreme flooding, but rested on an imperfect knowledge of the Gneiss properties as a natural abutment and did not give sufficient means to and care for the geological surveys & geotechnical monitoring prior to and after construction. A sad and instructive tale; Thanks for posting it. __ .

See, at the time of the disaster, several young men who died left behind grieving fiancées, some of whom turned out to be pregnant. Since at the time having a child out of wedlock was so detrimental to both mother and child, with approval from then president de la république, the grieving fiancées of Frejus were made widows by law, and later mother to legitimate children.

Prior to the dam's complete failure, were there any attempts to repair the cracks?

I think he said the cracks were identified but ignored. Given the erratic waterflow of the river, you'd have thought they would have had time to repair them - but perhaps publicly acknowledging their existence would have brought to light the dam being built 200m downstream from the originally intended site with no further geological surveys. Given John also said that it's best to fill dams at a constant rate, it doesn't sound as though they're best suited for such rivers anyway.

Would love to see you cover the 2020 breaks of the Stanford and Eden dams near Midland, Michigan. Thousands of people had to flee for their lives and the damage was estimated to be around $200 million of damage. It was so bad it caused Governor Gretchen Whitmer to declare a state of emergency and the area is still undergoing its recovery.

I think the Oroville Dam almost-complete failure is a story that should be more closely inspected - I have heard it said that the emergency spillway came within a hour of total fail

I looked at the map/satellite view of the site. There is a label Lac de Malpasset (Malpasset Lake) on a grove of trees. I think that lake has been gone since 1959. The photographs posted with the maps are interesting because there is a wall of the dam pushed out from the bottom and moved with other parts of the wall continuing over it.

To complete your video, in 2009 I visited the Frejus Town hall exhibition (if we can call it that) dedicated to the 1959 drama. In addition to the fact that the majority of the population was against the chosen site, it shows the long process of building this dam. Numerous strikes slowed down the construction of the building, the owner of the mine that the reservoir was to cover filed numerous legal appeals Last but not least, a block 20 meters long and 10 meters wide had been assembled with concrete of dubious quality. It is likely that this is the block where the reported leaks appeared. The guard had also warned the authorities that the use of dynamite for the construction of the nearby highway was causing small waves on the forming lake. The trial of the Malpasset dam disaster lasted 4 years and in 1971 the final judgment was that this disaster was due to inevitability.

Congratulations for your video! It's the first time I can hear the explanations about the Malpasset dam failure which was due to these reasons (the fault that prevented water from evacuating the foundations, the first time the dam was set under water pressure...). I can add a third cause of the unhooking of the construction: have a glance on the left bank of the river Reyran, you can see how smooth the surface the dam laid on is. That is a phenomenon called alkaline leaching which turns K-feldspar into soap on which concrete slipped under water pressure, especially when the ground is micaschists. Geologist Pierre Bordet, who issued a thesis on Esterel in 1951, quoted this fact in the sixties.

Some very important facts have been missed here, I did a TV investigation & report on this at the time of the opening of the memorial in Fréjus and interviewed François Léotard former mayor of Fréjus & later government minister. The A8 autoroute was under construction at the time of the disaster and during the filling phase, each time the highway contractors chain blasted the hillside which was perilously to the eastern wall of the dam, André Ferro the dams gardien reported severe rippling of the the water surface of the dams water during blasting, this was reported to the prefecture but ignored. Further to this as part of his responsibility he requested to bleed off water long before the critical level but was refused as the autoroute bridge was under construction down stream. Visiting the site it is clear, the eastern wall was not cut into the rock as the plans showed but rather butted to the face & secured with only 1 inch mild steel bars, combination of the blasting & poor workmanship contributed to the failure, The engineer André Coyne allegedly committed suicide & later André Ferro died under mysterious circumstances, I spoke to Gérard Ferro, the son of Ferro who alleges his father was murdered to silence him, I was told to play down the report as a blanket of secrecy was placed over the whole affair, make your own minds up.

The minute the contractor moved the location of original Dam the engineer should have Rejected it and resigned as the Engineer of Record. Not his fault.. Poor man must have died of heart ache from all the deaths. I am an Architect Engineer in New York and NO ONE is allowed to change anything on design without permission and extensive review of such.
