Je connaissais le monstre depuis en haut car notre famille avons un chalet à Pramarin. Il parait que mes parents s'étaient arrêtés une fois après le pont de Susten pendant un orage, mon père connaissant les conditions favorables pour la formation des laves car il était ingénieur au téléphone et s’était occupé du passage des câbles sur le site. Ma mère me raconte que c'était un mur qui avançait à pas d'homme et qui faisait un bruit épouvantable. J'y étais aussi mais je n'ai aucun souvenir, je pense que j'étais sous le choc mais que cela a dû rester dans mon subconscient. A Pletschen les maisons devaient trembler parfois. Il faut penser qu'avant il n'y avait pas les murs le long du lit du torrent et qu'il n'y avait pas tout le système d'alarme et de surveillance.

@@allenpeck8239 The dates are taken from the videos of this channel. Of course there are events in may, june or August too, but the accumulation in the last 10 days of july over these years is very signigicant. Actuallay what you need in the area is a thunderstorm with lot of prepicitation in a short time in the bowl area , and these are more likely in warm and humid conditions. The material transportet may be the most though in the first events after winter, because they move the debris out of the canyon, which accumulatet in the winter by frost blast and avalanches.

I love watching these things. Here's my theory on debris flow. The coefficient of friction is different for an object that is moving than one that is stationary. That's why when you're braking on a rainy day, you'll feel the car slowing and then you'll exceed the limits and the car appears to lurch in whatever direction gravity takes it. You can't just hit the brakes again and expect the car to slow. You have to deal with an object which is effectively more slippery than it was moments before even though its the same wet object. Before you lost control your tire was rolling at the same rate of speed. As it rolled, the tire kept pace with the tar moving past below. Now that you're skidding the tire isn't moving and the tar is going by very fast. The coefficient of friction is different. To get control back you have to pump the brakes or let your car equipped with traction control do it at high speed. Eventually your tire will once again be rolling along as fast as the road is sliding past and the old coefficient of friction will be in place along with control. Its the same with the boulders coming down the hill. Rolling, they're wet and somewhat supported by the thick goo which has momentum. Friction on the huge boulder is low. If they land on a flat side, there will be a lot more friction, but they still have the weight of all that goo pushing them ahead and goo underneath as well as a slimy surface under that. That's why they keep rolling and sliding, lower coefficient of friction and pressure from upstream and lower friction with surface. If the boulder topples onto one of it's flat sides and hits a dry level spot it most likely won't be moving again unless the upstream stuff hits it in a big mass. The next time you're standing next to a steep mountain or a cliff and you wonder why you aren't being covered in stone, its because of the coefficient of friction holding things together. That can change with a lot of rain or a shock that causes a tiny amount of movement. Suddenly the moving coefficient of friction will be put into place and you had better not be standing there because millions of tons will only stop when they run out of momentum or into lots of friction.

Well done, erm filmed Pierre. The movie of the Illgraben flood of 2000 and also 2014 is quite spectacular with its fast, compact front, but this on can top it in some aspects. Especially the tremendous push force able to move those giant blocs of several m3 in the front.

Merci pour ces images très instructives. Le front de cette lave torrentielle est constitué par un "amas mobile de blocs rocheux encastrés". Les blocs rocheux ne sont pas identiques, comme le seraient des pavés auto-bloquants, ni semblables, comme des pièces de puzzle. Néanmoins, ils forment une sorte d'encastrement mutuel, dans lequel chaque bloc du front trouve à s'encastrer dans les autres, en se remplaçant dynamiquement. Cet encastrement mutuel dynamique permet à cet ensemble de blocs volumineux de ne pas être dépassé par la matrice boueuse dense, ni submergé par une vague d'eau plus rapide, ce qui finirait par assécher la matrice, la ralentir voire l'immobiliser. Tant que les gros blocs ne sont dépassés ni par l'eau ni par la matrice, le processus de lave torrentielle s'entretient.

For "Pierre": It is simply astonishing, the extreme dangers that the authorities faced, in the construction of these illgraben channels designed to protect lives, property, and lands downstream. They had to work, knowing that this stuff could come hammering down at any time, any second, with the certainty that they could be killed, and that any improvements that they had so far accomplished, could be destroyed in seconds. I noticed in the "dump pit" at the base of the concrete lip, seemed to be catching most of the boulders, as only a finer slurry was flowing below them. So, they could present a big problem, once the flow stops. They could hold back subsequent materials, causing nasty bursts that may overwhelm the system, with unintended consequences. So, when the flow stops, do men . . . demolition experts . . . slowly and carefully blast away at the boulder piles?

Ces blocs ralentis tendent à se déposer sur le fond, ou n'avancent que par reptation et non par saltation (comme on dit pour la neige ou le sable dans le vent). La boue et l'eau tendent à les submerger. Mais quand la boue et l'eau accélèrent, et s'insinuent entre des blocs éparpillés, leur flux est de moins en moins laminaire, de plus en plus turbulent. Les blocs déposés sont à nouveau déplacés, absorbant par leur mouvement une partie de l'énergie cinétique de la matrice boueuse. Déplacés un à un, les blocs submergés tendent à former un massif de blocs sur le plancher. (Ch. Blanchet, "Formation et destruction par un courant d'eau de massifs en pierres", in La Houille Blanche, 1946). D'où un véritable dallage sur le fond du thalweg ou chenal torrentiel. Passant sur ce dallage, la lave torrentielle est plus à même de déborder du chenal. Mais les débordements latéraux sont rapidement immobilisés. On constate une élévation et un élargissement de la surface de la lave ; lave dont la partie médiane est la plus dynamique. Des massifs de blocs submergés peuvent générer un amas immobile de blocs rocheux encastrés entre eux. Ces amas immobiles de blocs rocheux encastrés s'allongent par sédimentation d'aval en amont. En conséquence, le débordement latéral de la lave remonte aussi vers l'amont. Sur une vaste zone, les gros blocs sont de moins en moins visibles à la surface. Vu de dessus, on semble assister à une coulée de boue, chargée de galets et de cailloutis. Mais, de temps en temps, des gros blocs rocheux sont à nouveau visibles : soit qu'ils roulent sur le dallage de blocs, soit qu'ils aient été arrachés de ce dallage. Ce sont : soit les blocs amont du dallage qui sont arrachés et qui roulent sur tout les autres, soit le bloc le plus aval qui est emporté, amorçant un démantèlement régressif du dallage. Le démantèlement régressif du dallage semble le cas le plus probable quand on voit de plus en plus de gros blocs isolés franchir le mur, tandis que la surface de la lave s'abaisse et amenuise son aire (superficie). Tant que les gros blocs rocheux détachés du dallage sont espacés, un nouvel amas mobile de blocs rocheux encastrés ne peut pas se produire. La lave torrentielle reste laminaire, en régime de croisière. On assiste alors à un démantèlement régressif (érosion régressive) du dallage constitué précèdemment par sédimentation de blocs d'aval en amont. Si plusieurs gros blocs rocheux sont détachés du dallage simultanément, ils peuvent générer un nouvel amas mobile de blocs rocheux encastrés. Une alternance de sédimentation de gros bloc en dallage et de démantèlement du dallage peut produire le rythme des bouffées torrentielles qui est l'originalité des laves torrentielles.

Bonjour, J’ai vécu cinquante ans à 15 km de ce lieu + un chalet non loin des hauts de l’Illgraben sans jamais savoir ce qu’était une lave torrentielle. Pourtant j’ai fait le collège scientifique à Sion (matu bac). J’ai vu la première fois le phénomène à la télé. C’était un reportage sur la disparition d’un alpage dans l’Oberland Bernois. Gros blocs entraînés dans une boue formée d’éléments plus fins allant jusqu’à la poudre. Son poids spécifique va de 1.8 à 2.2 kg au litre, ce qui permet de porter des blocs de granit. En principe c'est pas chaud, sauf chaleur générée par les blocs qui se concassent les uns contre les autres. (Par contre à la catastrophe de Bondo je pense qu'au coeur de l'éboulement la température à grimpé, ce qui a fondu la glace du glacier qui avait était emporté avec l'éboulement, ce qui forma une lave torrentielle). Regardez mes autres vidéos sur l’Illgraben. Vous y verrez un immense ravin, sorte d’entonnoir de 1000 m de haut sur un pourtour d’une dizaine de km. Ce que les spécialistes nomment le bassin versant. La pluie torrentielle tombe d’un coup et entraine avec elle les éléments de plus en plus gros, de cette terre jaune bien poudre après une période sèche, aux bons vieux blocs faisant en moyenne 20 T. Le gros dans ma vidéo du 22.07.2016 fait selon mon estimation 150 T. Au pied du ravin tous ces éléments se rencontrent s’assemblent puis sont poussés vers les bas le long d’un canyon qui le printemps est en plus encombré de reste d’avalanches et d’éboulis, puis d’un chenal pas toujours propre. Comment savoir si ça vient ou pas. C’est là qu’est le mystère. J’ai dû attendre deux ans avant de voir un front de lave. En principe un gros orage, une pluie soudaine (les deux dernières de cette année 2018 étaient inattendues, pas même le temps d’envoyer un message). C’est là après 20-30 minutes. Le lieu est sécurisé par des lampes d’avertissement et les fous qui s’aventurent dans le chenal ont à peine un quart d’heure pour quitter les lieux. Moi je n’ai pas osé y mettre un orteil, sauf une fois en automne par beau temps pour prendre des mesures et là encore il faut craindre un nettoyage au barrage de l’Illsee. La commune de Leuk pourrait permettre un tourisme d’intéressés par le phénomène en sécurisant le dessous du pont de la route cantonale. Lieux absolument déconseillé. Personne ne sait si ce qui arrive est normal ou énorme. De toute manière un jour ce sera giga. Si on élargit le chenal la lave freine et donc augmente de volume. Il faudrait garder le chenal fait par la nature mais donner au monstre tout l’espace nécessaire en cas de débordement, dont consacrer tout le dessous du pont à sa gracieuse intention, et laisser deux espaces de chaque côté sous le pont pour les intéressés par ce phénomène. Il parait que certains donneraient des millions. Quand ça passe, la terre tremble, le fracas est épouvantable, et il y a une odeur de soufre et de pierre pulvérisée qui se répand dans l’air. Ça remet l’orgueilleux en place, à moins qu’il soit irréductible.

La boue ne réussit pas à s'infiltrer entre les blocs rocheux et à y créer une pression interstitielle qui contribuerait à les écarter un peu plus et à disloquer le front rocheux de la lave. Les blocs ont des formes telles que la face aval qui subit la poussée de la matrice boueuse n'influence pas son comportement (avance, soulèvement par portance, abaissement par recouvrement). A l'arrière du front, on devine des blocs partiellement submergés, qui sont moins rapides que la matrice boueuse, dont les flux décollent en les dépassant, ce qui provoque des turbulences visibles en surface.

I assume it is steaming. Look @4:30, one can see the bubbles rise out of the sludge, like fumes out of Lava. I guess behind/down the "weir" something like a rotor/washing machine is formed like with pure water, crushing the blocks, +friction and pressure, as you said, producing enough heat to evaporate some water. In this video @9:30 it is steaming even more, and Monsieur Zufferey points out the crushing kzbin.info/www/bejne/oXebiKKEgpdmrbs In this video @1:50: one can see the "washing machine" with backflow where the sludgefall hits the lower level. Behaves like water, but is at least 2x as dense. I imagine some vapor here as well.

It isn’t steam. It’s rocks smashing down into other rocks and pulverizing them. It’s dust exploding up and out of the mud with all that force. The mud covers most of the rocks, but there are HUGE rocks we can’t see flowing just beneath the mud that smash together when they go over the edge, creating that white/grey dust.

More like 100-200 t. A 100 ton block would be the size of a cube with about 3,4 meter side length. The sludge which carries them along is almost as dense as the rocks themselves, something like concrete with 2,6 g/cm³, the rocks (quarzite) has about 2,7 g/cm³.

@@allenpeck8239 It´s not the first video of debris flow im watching ;) I´m a scientific interestet person, and was lucky to have a polytechnical high school in my town, instead of a musical, economical or humanistic orientated one. The internet provides a lot of information without the need to go to a library or catch the dictionary. When something is of interest, i read about it, when there are terms i don´t know or understand, i read about them ... but it´s a very time consuming hobby ;) Some kind of autodidact, but social contacts might suffer from it ;) Problem: 10 chrome sessions whith about 100 windows each opened at the same time, 2 weeks ago. On the other hand, don´t ask me questions about literature, i am a complete uninterested noob on this subject.

That's an incredibly well done resource! The necessity for such a detailed study must be of critical importance in such an environment. I've never given much thought to how much more locomotive force there would be behind something like the watershed from a rainstorm on the Swiss Alps than one might encounter on the Southwestern U.S. Thanks for sharing.

Is this a common event? It seems like it might be so considering the depth of the original channel through what seems like gravel and dirt. Obviously that drop was man made but was it built there with a specific purpose in mind? Lastly, how did you know to set up a camera at that point? Did you know this was going to happen and if so, how did you know?

That drop takes a lot of energy out of the falling material and reduces erosion further down. That, in turn, gives a measure of control over where the material flows.

So the water is just the lubricant. Probably 90%+ of the material in that slurry is everything from silt to boulders. This makes this a flood of basically liquid rock, not water. Rock is far heavier/denser than water, which is why it has the power to push those boulders along. It is super dense. Water alone couldn't do it unless it was moving faster and was deeper. This would be like swimming in a concrete mixer.
