dadu river landslide

The Shuangjiaping ancient landslide, located in the Dadu River, Sichuan Province, China, is an example of this case. It is 23 km away from the Pubugou Hydropower Station in the downstream region. Jun 10 A landslide dam on the Dadu River caused by earthquake ten days earlier collapses, killing 100,000 in the Sichuan province of China; Jun 29 Alexander Macdonell and over five hundred Roman Catholic highlanders leave Scotland to settle in Glengarry County, Ontario. Ten days later, on June 10 1786, the dam broke and the resulting flood extended 1,400 kilometres (870 mi) downstream and killed 100,000 people. Earlier this week on Thursday, a landslide left TWO people dead, 18 injured, and 31 others missing. Jul 29 1st newspaper published west of Alleghanies, Pitts Gazette A new landslide site that is more consistent with most historical documents is proposed, and a dammed lake formed by the landslide is defined and measured. Dadu river landslide dam 6. It is the second-deadliest landslide disaster on record. Using physically-based equations supported by recent physical model data, the maximum outflow may be estimated to be about 6,000 m3/s. The Kangding Louding earthquake of 1786 caused a landslide dam on the Dadu.

Ten days later, the sudden breaching of the dam resulted in catastrophic downstream flooding. View of the Mt.

The great European famine 1. overtopping was the primary cause of the Dadu river landside dam failure, although aftershocks may have further weakened the embankment. They show that the breach upper lip width reached the dam length (~220 m) about 35 min after breach start and that the maxi- Red triangles mark the locations of stations L6 and L7 at the entrance of two water tunnels. Shaanxi earthquake 3. It also created a 250 meter-long barrier blocking the Dadu river. This landslide was initiated along the weak layer of the bedding plane during the last glaciation in the late Pleistocene (Q 3) period, which was due to deep incision of the Dadu River at that time.

Plague of Justitian A detailed study of the 1786 Dadu River event is presented as the second chapter. The Hongyanzi landslide is located in the right bank of the Dadu River, a secondary tributary of the Yangtze River in Hanyuan County, Sichuan province in the Southwest of China (Figure 1). (1) (2) and (3) were applied to the Dadu river landslide dam breach development. Explosive work to blast and unblock Dadu river in southwest China's Sichuan Province has been postponed due to a new dangerous landslide. Compared to the previous work, new information to this historical event is discovered. As a result, a landslide dam blocked the river. Keywords: Landslide dam, Breach, Flood, Discharge. 2 where t is the time from the start of rapid breach development. Coringa cyclones 5. Typical results are shown in Fig. Krakatoa volcanic eruption of 1883 4. A stronger landslide effect implies that a higher percentage of channel length is buried by landslide-related sediment, leading to reduced river incision efficiency. Eqs. Chinese historic documents recorded that on June 1, 1786, a strong M=7.75 earthquake occurred in the Kangding-Luding area, Sichuan, southwestern China, resulting in a large landslide that fell into the Dadu River.
