The recent flood in the Sikkim Himalayan area, Sikkim and downstream areas are a classic example of Glacier Lake outburst-induced flash flood in the Teesta River that devastated the Sikkim state and northern West Bengal by killing hundreds of people besides livestock, buildings, roads, bridges and dams, and so on. Though the duration of the incident was small compared to other flood disasters in the country, it resulted in severe damage to property and life. Post-disaster satellite images depict that the size of the South Lhonak Lake was reduced to about 107.1 ha (the present size of the lake is 60.3 ha). The study reveals qualitative as well as quantitative analysis of during and post-GLOF situation which was due to an effect of highly intensive rainfall, the sudden beach of South Lhonak Lake and Chungthang dam faced by the riparian inhabitants. In this study, both primary and secondary data were collected from news channels, newspapers, the Sikkim government website, public conversations, and focused group discussions. After the 2011 earthquake, this was a large catastrophic GLOF in Sikkim. As a consequence, social, economic, and environmental aspects are intensively impacted by the GLOF (South Lhonak Lake) in Teesta River Basin (TRB). In the case of Mountain Rivers, such a circumference is quite natural, but precautions should be taken to minimise the risk.

摘要

The recent flood in the Sikkim Himalayan area, Sikkim and downstream areas are a classic example of Glacier Lake outburst-induced flash flood in the Teesta River that devastated the Sikkim state and northern West Bengal by killing hundreds of people besides livestock, buildings, roads, bridges and dams, and so on. Though the duration of the incident was small compared to other flood disasters in the country, it resulted in severe damage to property and life. Post-disaster satellite images depict that the size of the South Lhonak Lake was reduced to about 107.1 ha (the present size of the lake is 60.3 ha). The study reveals qualitative as well as quantitative analysis of during and post-GLOF situation which was due to an effect of highly intensive rainfall, the sudden beach of South Lhonak Lake and Chungthang dam faced by the riparian inhabitants. In this study, both primary and secondary data were collected from news channels, newspapers, the Sikkim government website, public conversations, and focused group discussions. After the 2011 earthquake, this was a large catastrophic GLOF in Sikkim. As a consequence, social, economic, and environmental aspects are intensively impacted by the GLOF (South Lhonak Lake) in Teesta River Basin (TRB). In the case of Mountain Rivers, such a circumference is quite natural, but precautions should be taken to minimise the risk.
