The Gerkhozhan-Su river valley is one of the most prone in terms of debris flow formation in the North Caucasus Mountains. This work aimed to apply a chain of mathematical models to estimate debris flow characteristics. The simulation was carried out along the river from the upper reaches to the top of the debris flow cone. The choice to apply one...

The study deals with the modeling of a possible outburst flood with the example of glacial lake Varshezkul Lower located in the Western Pamirs. From the formation of the lake in 1968 and until 2022, the lake increased by 8.3 times, its active growth was observed until 2000. According to the survey of the valley in 2018, the volume of the lake was 1...

Three likely scenarios of debris flow development in the valley of the Gerkhozhan-Su river are discussed: (I) the passage of a debris flow comparable with that in 2017; (II) a shift of Buzulgan rockslide and the formation of a rock-dammed lake with a dam 20 m high; (III) a catastrophic shift with the formation of a lake with a dam 40 m high. The ch...

On July 8, 1998, the deadliest glacier lake outburst flood (GLOF) in Central Asia for at least the last 100 years occurred in the Shakhimardan catchment, Kyrgyzstan. Most of the >100 victims were, however, killed in the Uzbek enclave of Shakhimardan, i.e. in the downstream part of this transboundary catchment. No warnings were issued between the tw...

One of the most far-reaching glacier-related hazards in the Tian Shan Mountains of Kyrgyzstan is glacial lake outburst floods (GLOFs) and related debris flows. An improved understanding of the formation and evolution of glacial lakes and debris flow susceptibility is therefore essential to assess and mitigate potential hazards and risks. Non-statio...

New data on continuing advance of the Kamchatka glaciers Erman, Vlodavets, Sopochny, Schmidt, and Bogdanovich were obtained as a result of analysis of aerospace information taken at different times. Glacier Erman advances during the past 70 years (1945–2016). Over the period from 1949 to 2016, its area increased by 4.7 km2 and the length – by 3.3 k...

This research is devoted to Tangjiashan Lake, a quake landslide-dammed lake, situated in Sichuan Province, China, which was formed by a landslide triggered by the Wenchuan Earthquake on 12 May 2008. A STREAM_2D two-dimensional hydrodynamic model of Russia was applied to simulate the process of two flood scenarios: 1, lake dam outbreak, and 2, dam o...

Climate change has been shown to increase the number of mountain lakes across various mountain ranges in the World. In Central Asia, and in particular on the territory of Uzbekistan, a detailed assessment of glacier lakes and their evolution over time is, however lacking. For this reason we created the first detailed inventory of mountain lakes of...

At 16:30 (Beijing time) on August 3rd, 2014, an Ms 6.5 earthquake occurred in Ludian County in Yunnan Province, China. The Ludian earthquake triggered a collapse in Chapingzi, right bank of the Niulanjiang River, and a landslide in Hongshiyan at the left bank on the same location. These events occurred 1.5 km downstream of the Hongshiyan hydropower...

Glacier lakes pose threat to downstream settlements and infrastructure. In recent decades the number and area of lakes have been growing at an accelerating rate due to worldwide glacier shrinkage. In the Russian Caucasus this process is understudied. We present results obtained during a 12-year (1999–2010) continuous field monitoring of the Bashkar...

Measuring the internal velocity of debris flows is very important for debris flow dynamics research and designing debris flow control works. However, there is no appropriate method for measuring the internal velocity because of the destructive power of debris flow process.

The Wenchuan (汶川) earthquake on 12 May 2008 induced a large number of landslides, collapses, and rockfalls along the Longmenshan (龙门山) fault. The landslide in Niujuan (牛圈) Valley (named Niujuan landslide), close to the epicenter, is one that travelled a long distance with damaging consequences. Using QuickBird satellite images and GIS tools, the se...

Numerous glacier lakes have formed in recent decades due to worldwide glacier retreat induced by climate change. These lakes, dammed by glaciers and moraine ridges, are hazardous because of potential glacial lake outburst flows (GLOF). The GLOF probability is increasing in the Russian Central Caucasus, like at the Bashkara glacier which has been ex...
