Pilot Projects: Uzbekistan

In the Pskem River basin, GLOFCA works to reduce flood and landslide risks from large glacial lakes threatening villages, hydropower, and tourism in Tepar and Pskem.

Pilot site 1 & 2

  • Overview: Pskem River Valley
GLOFCA pilot site in Uzbekistan
The two pilot sites of the project—Tepar and Pskem villages—are located in the middle reaches of the Pskem River, on its highest terrace. Pskem Village is the last populated settlement in the river valley, with beekeeping sites, national park checkpoints, border posts, and the Maidontal and Oigaing meteorological stations situated further upstream. The population of Pskem Village is 1,035 people (420 women, 615 men, and 17 individuals with disabilities). The population of Tepar and Takayangak villages, which form one administrative unit, is 960 people (447 men, 486 women, and 15 individuals with disabilities). In the upper reaches of the Pskem River lie the glacial lakes Shavurkool and Ikhnach, with volumes of 4.5 million and 5 million cubic meters, respectively. The area is highly susceptible to active exogenous processes, including mudflows, landslides, and rockfalls.
  • Hazard Exposure and Risk
The Pskem River Basin houses the Teparsai Hydropower Station, with the smaller Mulallinskaya Hydropower Station located downstream. In 2023, the construction of the Teparsai dam was completed, raising the water level by 160 meters and forming the Teparsai Reservoir, which spans approximately 20 kilometers and has a capacity of 500 million cubic meters. Additionally, the construction of the Taliksai Hydropower Station is underway, with the KarangitugaiHydropower Station planned for the future. The construction activities, including blasting and transporting rock materials, as well as the development of major transport routes for delivering construction supplies, have disrupted the geological integrity of the terrain. This disruption can potentially activate ancient landslides with volumes of 20–30 million cubic meters and trigger new technogenic landslides. Rockfalls into the Pskem River could generate waves capable of damaging downstream dams. The river’s maximum discharge exceeds 200 cubic meters per second. The region is also vulnerable to mudflows caused by rainfall, snowmelt, and glacial melt. These processes pose ongoing risks to personnel at construction sites and the increasing number of tourists visiting the area.
  • History
Rain-induced mudflows have been recorded in the Pskem River Valley, causing damage to infrastructure and partially blocking the riverbed. Although no outbursts from glacial or moraine-dammed lakes have occurred to date, there is potential risk, particularly from the lakes in the Ikhnachkul system and the moraine-dammed Shavurkool Lake.
  • Measures
To mitigate risks, regular aerial and expedition surveys of the lakes in the Pskem River Basin are conducted by UZGIDROMET and the Institute of Geology and Geophysics. These include bathymetric and hydrometeorological observations.
  • Cultural Significance
The development of hydrotechnical infrastructure and the growth in tourism have significantly increased anthropogenic pressure on the region, emphasizing the need for additional disaster risk reduction measures.
  • GLOFCA Project:
In 2025, as part of the GLOFCA project, monitoring equipment will be installed on high-risk lakes (Ikhnachkul system, Shavurkool, and Urungach system) to monitor water levels and hydrometeorological conditions, along with early warning systems as needed. Landslide monitoring sensors will also be installed. The data collected will support risk assessment and mitigation, ensuring the safety of local communities and construction sites.
