DEHRADUN: The much-awaited report of the skilled committee set as much as confirm the causes of the land submergence catastrophe at Joshimath earlier this yr has been made public.
The committee has raised questions concerning the ‘load carrying capability’ however then again, the skilled committee has given a clear chit to the National Thermal Power Corporation (NTPC), which has been focused by numerous organizations and other people of Joshimath for this land submergence.
With the federal government making public the report of scientific establishments, the truth of the Joshimath land submergence has began coming to the fore. “The rocks have slipped due to water leakage inside the ground of Joshimath located in the Moraine area (soil brought by the glacier), causing the ground to collapse,” the report stated. Glacial moraines are fashioned by the deposition of fabric from a glacier and are uncovered after the glacier has retreated.
The most stunning revelation within the report has been present in a research performed by the National Geophysical Research Institute (NGRI) Hyderabad. According to this report, “evidence of land submergence has been found in Joshimath up to a depth of 20 to 50 meters”.
According to the report, “The floor situations noticed there have been discovered to be as much as a depth of fifty meters in lots of locations. The fundamental causes for land submergence embody the development of buildings past the ‘load-bearing capability’ of town, lack of drainage, deforestation, obstruction of paths of pure water sources, and enlargement of buildings.
The Geological Survey of India (GSI) and the National Institute of Hydrology (NIH) of their report after a research at Joshimath have given a “clean chit” to NTPC’s 520 MW Vishnugad hydroelectric venture on the Alaknanda River in Chamoli district. Following protests by native residents, the state authorities had on January 5 stopped all work on the NTPC venture website.
The Wadia Institute of Himalayan Geology report highlights, “The soil structure of Joshimath is a complex mixture of boulders, gravel and clay, the boulders here are also made of gravel and clay brought from glaciers, which is a major reason for their slipping”. According to the report, inside erosion in such soils causes instability in the complete construction. This is adopted by readjustment, ensuing within the boulders collapsing.
“The main reason for the submergence appears to be internal erosion and with the expansion of Joshimath, the flow of the natural drain flowing from above has been disrupted,” the report stated. “Drain water is continuously seeping into the ground which has increased the level of damage due to excessive rainfall over the past 10 years”, the report highlighted.
