Underestimated mass loss from lake-terminating glaciers in the greater Himalaya

Guoqing Zhang et al.

Summary: According to satellite observations and bathymetric measurements, accounting for subaqueous melting from lake-terminating glaciers increases estimated glacier mass loss across the Himalaya by 7% over the past 20 years. This underestimation is due to the omission of subaqueous mass loss in geodetic methods, which do not account for the replacement of ice with lake water.

Modeling Potential Glacial Lake Outburst Flood Process Chains and Effects From Artificial Lake-Level Lowering at Gepang Gath Lake, Indian Himalaya

Ashim Sattar et al.

Summary: Glacial lake outburst floods (GLOFs) pose a serious threat to Himalayan communities, but mitigation strategies are limited and future hazards are rarely considered. This study assesses the current and future GLOF hazard for Gepang Gath Lake in the Western Himalayas, considering rock and ice avalanches cascading into the lake from areas of degrading permafrost. The study evaluates different scenarios of GLOF impacts, erosion patterns, and debris flow hydraulics, taking into account the engineered lowering of the lake. The findings demonstrate that the size of the future lake does not determine the size of GLOF events in Sissu, highlighting the importance of avalanche location and impact. Lowering the lake by 10 or 30 meters can reduce the high-intensity flood zone, but the Sissu helipad remains at risk under moderate-to-large scenarios. This study provides insights into the effectiveness of lake lowering as a GLOF mitigation strategy.

Analyzing the triggering factors of glacial lake outburst floods with SAR and optical images: a case study in Jinweng Co, Tibet, China

Liye Yang et al.

Summary: This study systematically analyzed the contributing factors to the glacial lake outburst flooding (GLOF) disaster, including meteorological triggering, glacial activity, lake expansion, landslide, and glacial collapse, using multi-source remote sensing approaches. The research found that heavy rainfall, landslide, and ice collapse within a short period of time likely caused the GLOF event in June 2020.

Monitoring glacial lake outburst flood susceptibility using Sentinel-1 SAR data, Google Earth Engine, and persistent scatterer interferometry

Sonam Wangchuk et al.

Summary: Continuous monitoring of glacial lakes and their surroundings is crucial due to the risk of lake outburst floods. This study demonstrates the use of Sentinel-1 SAR data and PSI technique for monitoring lake outburst susceptibility and seasonal/periodic changes in glaciers and lakes. The approach has the potential to be applied to other geographic regions facing similar challenges in glacial lake monitoring.

Improving the accuracy of glacial lake volume estimation: A case study in the Poiqu basin, central Himalayas

Miaomiao Qi et al.

Summary: This article introduces a volume-scaling relationship for moraine-dammed lakes based on the predictability of lake geometry parameters, and evaluates its performance compared to other formulas. The study finds that the new relationship shows a more robust performance and has no regional restrictions in the Himalayas. Additionally, using the new approach and high-resolution imagery, the sequential mapping of lakes in a basin reveals an increasing trend in total lake volume.

Glacial lake outburst flood hazard under current and future conditions: worst-case scenarios in a transboundary Himalayan basin

Simon K. Allen et al.

Summary: This study aims to demonstrate the assessment of the threat from a future lake and worst-case scenarios from current lakes, and how this information is relevant for disaster risk management. The results show that GLOF discharges from rock and/or ice avalanches could be much larger than previously observed or anticipated. The warning times in Nyalam are very limited. A comprehensive approach to disaster risk management is needed to address the current GLOF risk and consider worst-case catastrophic events.

Future Glacial Lake Outburst Flood (GLOF) hazard of the South Lhonak Lake, Sikkim Himalaya

Ashim Sattar et al.

Summary: This study assessed the future glacial lake outburst flood (GLOF) hazard of the South Lhonak Lake in the Sikkim Himalaya, considering the potential impacts of continued glacier retreat and avalanche events. The results indicate that the lake's growth may lead to overtopping of the frontal moraine, triggering GLOFs and causing significant downstream impacts.

Simulation and Assessment of Future Glacial Lake Outburst Floods in the Poiqu River Basin, Central Himalayas

Taigang Zhang et al.

Summary: Glacial lake outburst floods (GLOFs) are common natural disasters in high mountain regions, and the expansion of glacial lakes in the Himalayas due to climate change has raised concerns. Hazard assessments on certain glacial lakes suggest potential widespread damage that could impact both China and Nepal.

A massive rock and ice avalanche caused the 2021 disaster at Chamoli, Indian Himalaya

D. H. Shugar et al.

Summary: On February 7, 2021, a catastrophic mass flow hit the Ronti Gad, Rishiganga, and Dhauliganga valleys in Chamoli, Uttarakhand, India, causing extensive devastation and casualties. The collapse of rock and glacier ice led to a debris flow that transported large boulders and scoured valley walls, highlighting issues related to monitoring and sustainable development in high-mountain environments like the Himalayas.

Expansion and hazard risk assessment of glacial lake Jialong Co in the central Himalayas by using an unmanned surface vessel and remote sensing

Da Li et al.

Summary: Glacial lake outburst floods (GLOFs) are a severe hazard in the Himalayas, primarily influenced by glacial lake expansion, volume increase, and climate change. A lack of systematic assessment and field surveys puts downstream residents at great risk. Comprehensive investigations are urgently needed to understand the relationships between lake expansion, dam conditions, and GLOF risk.
