Abstract: Baige and Milin are two villages sitting on the riverside of Jinsha River and Yarlung Zangbo River, and they experienced large-scale landslides and glacier debris flow twice at the same site in the Tibet Autonomous region between October 10th and November 3rd of 2018. Deposits from the landslides and debris flow blocked the mainstream of the Jinsha River and the Yarlung Zangbo River, and formed barrier lakes, which posed serious threats to lives and property of local residents in the upstream and downstream of the landslide dam, along with the safety of downstream water conservancy facilities built or under construction. We undertook brief review on the four barrier lakes formed in the Jinsha River and the Yarlung Zangbo River, and the corresponding emergency response countermeasures. We summarize some experiences and enlightenments during the emergency responses, and put forward suggestions on improving technical support to such accidents, so as to provide reference for dealing with similar accidents in the future.
