First: Cloud torn or not …
It is surprising that there was not so much rain on the site of the meteorological department, which the situation like cloud bursting. According to the Meteorological Department, on August 4 and August 5, there was 8 mm to 10 mm of rain. Retired scientist Glacieologist Dr. DP Doval of Wadia Institute said that the situation of cloudburst that is created is not being set. Cloud bursting means rain above 100 mm in an hour. But according to the IMD, 8-10 mm of rain was recorded till 8.30 am on the night of August 4 and August 5. Flash flood came in the afternoon. Because of which it is believed that cloud bursting is not the reason for this flood.
Uttarkashi District Disaster Management Officer Shardul Gusaini said that three incidents of cloudburst have been recorded. In front of Dharali, Harshil and happy top. He said that the initial reason is the cloud burst. If new data will come in the morning, then the situation will be cleared. Can not deny any reason right now. Because the weather was fine a day earlier. It was raining less. But where does it take to change the weather on the mountains.
Second: temporary lake or dam formation and rain breakage
Retired scientist and glacieologist Dr. DP Doval interacted with Aajtak.in. They said that-
“Dharali is situated in the flood plane. I had already warned. There is one and a half kilometers long and very dense forest behind Dharali. The kheer car from which the flash flood passes through the same forests. Mount Srikanth is full of snow. But the speed with which the flash flood is not going to burst. The cloud is not going to burst. The cloud is not clouded. The flood flood is slow. Gets “

A. To become temporary lake
The forest over the speed of the flash flood reflects a situation like a temporary lake, water deposition or natural dam. The water came at a speed of about 43 kilometers per hour. The same pace was in 2013 at the time of Kedarnath disaster, the flood came out of the breakdown of Chorabari Lake. The second is that Dharali and its side are very narrow Valley. There is a high mountain. If someone Glacier If the temporary lake breaks down on the water deposition or natural dam, it breaks it. In the video that has come, the water coming from above is black. Debris is also gray colored.
Doval says that such water and debris have come due to the breakdown of the frozen place. But in the last few days, no such lake was seen in satellite pictures there. Maybe there is somewhere in the middle of the forest. On which a stone has fallen or weakened due to continuous rains. Because of which the flash came flood. Just like an accident. The dirty debris stored in his temporary lake, dam also came down.
B. There was already two lakes
If you try to understand the area with Google Earth, then it seems that there are two glaciers in the top catchment area of the mountain behind Dharali, in which big cracks are visible. It may have come from here that the ice Evelyn would have come, due to which the debris accumulated in the glacier came down rapidly. If you look at the video of the devastation in Dharali, then the flood is seen coming down very fast. The reason for the speed of the inundation is also the step slope.

Google image was also revealed in 2022, in which two small lakes were also seen near the glacier above. Which was then on the verge of meeting each other. There is also a possibility that now both these lakes have been found and then Evely has come, which caused havoc at the bottom. Like in 2021, in the Rishiganga disaster in Chamoli district.
Third: Due to changing the climate, now clouds are bursting even at the height.
Doval also said that nowadays cloudburst due to climate change can occur at an altitude of 3-4 thousand meters. Which was earlier at a height of 1 or 2 thousand meters. Usually there is no rain at an altitude of 3-4 thousand meters. Snowfall occurs. But this pattern has changed due to climate change and rising temperature. Now if it rains continuously, it will break the glacier. If this glacier falls on a temporary lake, its weight will break the lake and will come down fast.
What is showing the video of Dharali’s destruction
If you watch the video of the devastation in Dharli carefully, then it seems that this flood came down very fast due to the sudden breakdown of something. The inundation that has come is not only water, but also the material of slurry type is also seen in it, which has brought all the above deposits down.
The possibility of damage due to destruction in Dharli is also more because there is dense settlement here. There is a area adjacent to Dharali, Gangotri and Harshil. Which is very famous among tourists. Due to the tourist area, there are also a large number of hotels and home stays in Dharali market. Because of which there is a lot of settlement around the river (River Bed). Because of which there is more loss there.
What is the occurrence of cloudburst?
Cloud bursting is a natural phenomenon in which a small area receives more than 10 centimeters (100 millimeters) in an hour. This happens in hilly areas like Himalayas when hot air and moist clouds collide with the mountains. Suddenly heavy rain starts. Due to this, the drains come in spate. flood And there is a situation of landslides, which people call Himalayan tsunami. This incident is so fast that it is difficult to predict in advance.
