Emergency Response and Thinking of Risk in Baige Barrier Lake in the Jinsha River
Landslides occurred twice in Baige Village, Jiangda County, Changdu, Tibet on October 10 and November 3, 2018, blocking the main stream of the Jinsha River and forming a barrier lake. After the occurrence of the significant event, entrusted by the National Energy Administration, China Renewable Energy Engineering Institute quickly established a Technical Emergency Response Team and scientifically studied and judged the risks of the barrier lake and accurately predicted the flood caused by break of the barrier lake with the support and cooperation of all relevant organizations. In the shortest time, it studied, formulated and implemented a series of emergency response schemes, such as the manual excavation of the barrier, the removal of the cofferdam of Suwalong Hydropower Station, and the emergency water discharge of Liyuan Hydropower Station, which effectively alleviates the disaster and risk, and ensures the safety of hydropower projects under operation and construction in the lower reaches. Combined with the experience of this risk treatment, this paper considers and predicts the risk assessment, emergency safety management, joint dispatching of cascade reservoir, etc. of the river basin water at cascade level.
