The Jinsha River is the upper reaches of the Yangtze River. It is also called the Chin-sha Chiang or Kinsha Kiang (Fig. 1) (Wikipedia 2018). It flows through three provinces, i.e., Sichuan, Yunnan, and Tibet, in western China.

The landslide was huge and blocked the Jinsha River (Figs. 2 and 3) (Dave 2018). A barrier lake was formed and the water level rapidly rose. The length, width, and height of the barrier lake were respectively about 5600 m, 200 m, and 70 m. The landslide struck around 5 am on October 10th. At noon of that day, the water level in the barrier lake had risen by 40 m and the amount of water reached 150 million cubic meters. By 7 am on October 11, the water level of the lake had risen by 59 m and the amount of water reached 360 million cubic meters. The water level rose at an average rate of 1 m an hour. On October 14, the...
