The Story about interest in the Bureya theme in the evening on December 28, 2018
Evening. The Internet user turned on the computer and decided to read the news. "What about the Bureya river and the Bureya natural dam?"
The user typed in the search box of Yandex the word "Bureya", then, - the word "Bureyskaya HPP".
Journalists write ... But what?
There are some clarifications on certain points: on the distances to the natural dam (for example, "Part of the hill fell into the Bureya river in 73 kilometers from the village of Chekunda of the Verkhnebureinsky district of the Khabarovsk krai"), on the volume (a) of electricity generation at the Bureya HPP ("the average daily output is 19 million kW.h), (b) a "collapsed" elements of the mountain (hill) ("about 34 million cubic meters")...
More significant is that two concepts (hypotheses) are formulated.
1) It was not a meteorite ("the Scale of the landslide in the Khabarovsk territory is too large for a meteorite, so we are talking about a geological phenomenon", "NASA satellite network regularly monitors all the falling objects onto the Earth. A meteorite of this magnitude would have been recorded ... At the same time, a day later, the place of the probable fall would accurately tracked based on the trajectory."
Not a meteorite...
2) About "a river tsunami 40 meters high". ""That tumbled-down wood on the opposite river bank. At first thought it was a landslide. But height seemed big, and the head of the district insisted that there the wood was before a landslide. Familiar professor wrote to me that the landslide should be with a splash of water because it fell in water. Then I compared photos, and found traces of this phenomenon which incontestably indicate that when falling a landslide there was a water splash. And its height was up to 40 meters. It passed to other coast, demolished all trees up to the roots, and the wave climbed the valley of the river Sredny Sandar (inflow of the Bureya River) on four kilometers upstream. A tsunami in the Far East taiga - such here improbable anomaly", - Makhinov told". [deputy director of Institute of water and environmental problems of the Far East office of RAS, doctor of geographical sciences Alexey Makhinov].
Curious concept (hypothesis). What has to be the speed of "landslide" to lift a wave 40 meters high? The landslide is after all, - a landslide, but not the high-speed device...
Then let's discuss, for example, a difference between the concepts "landslide" and "falling" ... Whether though "falling" will be able to lift, to push a wave 40 meters high?... It what has to fall? Well, not a meteorite?...
Mentally imagine an experiment. In a big plate you pour water. Then in the middle of the plate pour a hill of loose mass (for example, some cereals, grain). Partially this hill of grain rises above water. Then take a spoon and move the grits, grain from under the hill (at the base of the hill). Grits, grain from the top of the hill and from the "slope" begins to pour into the water. Primitive? But no matter how primitive, - it is clear that loose weight, grain has to be displaced with an enormous speed down, with enormous energy, if you want to lift, to push a little essential wave.
Wave of 40 meters?. Capable to break trees?.
The landslide by its very nature "moves" more or less gradually, consistently...
Another consideration.
"The blockage approximately in 70 km from the settlement of Chekunda has length about 800 m, width over 400 m and height from 80 m to 160 m"
If so-called "blockage" ["obstruction"] [dam] has length about 800 m, then how able such a "dam" to create a wave, which tumbled down the wood on the area nearly 1.7 sq.km? What configuration of the site on which trees are tumbled down? It is a rectangle with a total area of 1.7 sq.km, - with one party of 800 m and other party, let us assume, 2125 m (2.1 km)?
It would be nice, of course, to get acquainted with a fragment of a large-scale map... it Seems that there are automatic mapping systems?...
Somehow strange this hypothesis (concept), - about "a river tsunami", - appeared...
Tsunami not a needle, it in a box you will not hide.
Well, let's not make a too much emphasis on our thoughts... However, we have to assume that before we suggested that the landslide itself could not break the trees (by its very nature), the concept of "river tsunami" was not put forward (by anyone).
There was no tsunami. And then somebody thought, and came to the conclusion...
Science, of course, evolves. Discussion helpful...
Except an image of the primitive mound of grain on a plate with water the image of a grass snake on a frying pan in addition appears...
There are more an online travel information for tourists to the point "Bureya anomalies". If the river is divided (divided in whole or in part?) on two parts of - this anomaly? It may be...
So, got acquainted on December 28, 2018 late at night with news. There are specifications, there are additional concepts (hypotheses) - at least, two, there is information on (possible) trips of tourists.
But except all this there are also questions. For example:
1. It would be curious to learn how Bureya River drain indicators (for example, around the Bureya hydroelectric power station) change? The actual indicators are other than, differ an expected (assumed)? And in what degree?
2. What is the dynamics of flooding of new areas - if they are flooded. Yet the new (filling) reservoir does not have the shape of a vessel with vertical walls?.. Takes up some extra space?
3. In what degree of readiness the scientists and experts are? They were, seemingly, going to leave (again) to the place of emergence of a natural dam?
"... As reported in the RusHydro company, [hydroelectric power station] located on the Bureya River in the Amur region, operates normally, according to instructions of the Federal Agency for Water Resources (FAWR). ... FAWR did not instruct on change of working hours of hydroelectric power station. Water in the reservoir is still sufficient to provide the necessary amount of electricity. Overlapping of the river with a blockage of rocks, which was formed in a remote area about 100 km above the hydroelectric power station, currently has no effect on the operation of the station. Specialists of Bureya HPP strengthened monitoring of water inflow into the reservoir. The expedition of power engineers, who visited the site of the blockage, confirmed the almost complete overlap of the river with the landslide. Currently, the specialists ... are calculating ... on the basis of different scenarios of elimination of the blockage in the river"...
If "in accordance with the instructions of the Federal Agency for water resources (FAWR)"... Moreover, "FAWR did not give instructions on changing the modes of operation of the HPP.".. then of course... It... it is clear... "Overlapping of the river ... has no impact on work of the station now".
However, whether it is worth worrying (excessively). There are traditions.
People of life rejoiced and walked during festive demonstration in Kiev in 1986 (and not only in Kiev).
"On Friday, August 14 [1998], Russian President Yeltsin said: "there will be no Devaluation. I say this clearly and firmly. And I here not just dream, it's all calculated...". But three days later, on the morning of Monday, August 17, 1998, the Russian Government and the Central Bank announced a technical default on the main types of government securities."..
In General, all OK...
