February 6th 2021, Nanda Devi range of the Garhwal Himalayas, a chunk of rock around 400 meters in diameter, three times as large as a cricket ground, broke off for each parent mountain and fell onto an overhanging glacier at 5600 meters above sea level.
As the massive piece of ice gave way, rocks and mud tumbled down in an avalanche, falling straight into the path of the wrong key river, which was flowing between mountain crevices at the height of three and a half. 1000 meters, the falling debris created an ad hoc damn temporarily blocking the rivers flow and forming a lake as the wrong thing continue to flow into this newly created lake.
The pressure on the dam began to grow 8 hours later on the morning of February 7th, and the DAB gave way as the mass of rock and mud gushed out, destroying everything in its path, leaving 200 dead or missing and damaged 4000 crores worth of property. Obliterating two power plants, witikka completely and Dolly Ganga patchy, this sequence of events was determined when a team of five geologists took pictures of the area from a helicopter.
We studied the satellite images and added to it what we saw. This is just a preliminary report. We cannot say that we were not warned. The K they’re not. Deluge in 2013. Destroid 24 hydropower projects. People protested outside the author and High Court when the Vishnu Ganga hydro project was proposed for reconstruction.
An expert committee headed by Doctor Ravi Chopra that the court-appointed even cautioned the riverbed profile had changed significantly. We suggest not to construct any hydropower plant in the upper Himalayas. But the problem is that with Eric, and despite having the potential of generating 12 gigabytes of hydropower, the second-largest in India has an acute power shortage and spends over 1000 crore each year in buying electricity.
How can they know the water cascading into rivers that potentially contain the energy equal to several nuclear bombs? At present, there are 86 hydro projects with a cumulative capacity of around 2.6 gigawatts. Operational interaction and more are on the way.
So the real question everyone is asking is whether this tragedy was due to climate change or a natural occurrence. Glacial lake outburst flood GL OF the name given to flash floods in snowy mountains happened in Russia in 1968 and in 1970s Alaknanda flood.
The problem is not the only climate change though it is a contributing factor. Some experts like neighbors Pemadam show, however, believe otherwise. So tragedy in Lutheran is a tragic reminder of the dangers we face from climate change. Yes, the science backing him warming is to increase the thermal profile of ice from minus 6 degrees Celsius last century to minus 2 degrees. Now melting glaciers create lakes 400 large ones at last count in the Himalayas up from 127 in 2005.
That can cause flash floods, impeached, but how is 1 to monitor so many glacial lakes? Key benchmark glaciers in every basin should be monitored, and the results extra politics, some amount of monitoring is already happening through satellite imagery and remote sensing technology. But the information can be better enhanced by putting people on the ground who can install equipment to measure changes in water levels, discharge balances, etc.
Presently there is a wealth of information collected by different agencies lying all over the place that needs to be coordinated. Annual monitoring by an appointed nodal agency can help determine when to drain a lake and reduce the threat of GLF by building side canals. Other threads are developmental activities like the 719 kilometers Chardon Rd, partly built by uprooting vegetation along river slopes, which was criticized.
Environmentalists, also aghast when it was found that 56,000 trees would be cut for its creation in response to their petition, a 3 judge bench of the Supreme Court in 2020 ruled against broad, with highways of the project to minimize damage.
However, the government is mindful of this and has been allocating larger funds towards green energy. Even though cold still gets the bulk of the energy budget, Costa Rica Doe is a unique country in that it generates more than 98% of its electricity from renewable sources. 75% of it from hydropower, however, their hydropower generation depends on rainfall and not glacial waters, so it is not as prone to flood damage as India. Unfortunately, while the project report studies pollution, River flow, environmental assessment, and forests, glacier aladji is not part of their study.
It is also alleged that legal loopholes are often used to pass environmental assessment reports as such projects are a monetary windfall for the political Babu and contractor logging. In 2011, fifty-six power projects in North Eric were cancelled after it alleged that 17 were allocated to just four entities.
Fortunately, the author account also has the option of harnessing wind energy to solve its electricity problems. High wind speeds in Lutheran due to low-pressure belts. His ID for windmills with monocle, Herschel, Dorian, Rancy areas all having a minimum wind speed required to rotate turbines. The 2.4 MW project at virtually Colin Terry gave all became the first windmill. Project another account in 2013.
However, we know that despite this tragedy, hydropower projects will continue to be built. An in fact needs to be built to solve India’s energy needs, but to minimize loss of life and property, preventive measures and disaster management preparation should be prioritised. Bispo’s Limerick flash floods and author acharnae happening too often. Hydro projects or bridges everything they flatten. Is it a natural event, or are we living our own torment? Whatever be the cause. To nature, we must suffer.
