Glacial change and hydrological implications in the Himalaya and Karakoram
2021年2月2日 · Glaciers in the Himalaya–Karakoram mountain ranges harbour approximately half of the ice volume in High-mountain Asia and modulate the flow of freshwater to almost 869 million people within the...
Assessing climate-driven impacts on Karakoram glacier surge: A ...
2024年8月30日 · The Shishper Glacier in the Karakoram range underwent accelerated flow, leading to the formation of the Shishper glacial lake and posing a significant threat of GLOFs to the downstream region. Analysis of peak water discharge data during GLOF events reveals insights into the dynamics of catastrophic events, with the GLOF in May 2022 exhibiting ...
Basin-scale spatio-temporal development of glacial lakes in the ...
3 天之前 · Glacial lakes are expanding exponentially in the cryospheric environment of the Hindukush-Karakoram-Himalayas (HKH). Rapid glacier melting due to an above mean global annual temperature increase in HKH is attributed as the main reason for the expansion of the glacial lakes. ... Glacier-glacial lake interactions and glacial lake development in ...
Increasing glacial lake outburst flood hazard in response to …
2021年1月1日 · Glacier lake outburst floods (GLOFs) in the Karakoram. (a) Location of historical GLOFs sites (black dots) and the identified lake during remote sense era (blue dot), surge glaciers (dark brown shading), and the inventory of GLOF from the responsible glacier in (b-g) with temporal record in the five main valleys.
Future growth and decline of high mountain Asia's ice-dammed …
2022年8月26日 · Here, we focus on the future evolution of potential ice-dammed and supraglacial lakes in High Mountain Asia, as such lakes are responsible for the majority of glacier lake outburst floods in...
Monitoring and Disaster Assessment of Glacier Lake Outburst in …
4 天之前 · To explore reproducing the evolution of GLOFs with sparse observations in situ, this study focuses on the outburst event and corresponding GLOFs in August 2018 caused by the Kyagar Glacier lake, a typical glacier lake of the HMA in the Karakoram, which is known for its frequent outburst events, using a combination of multi-satellite remote ...
Surge-type and surge-modified glaciers in the Karakoram
2017年11月13日 · Some 221 surge-type and surge-like glaciers are identified in six main classes. Their basins cover 7,734 ± 271 km 2 or ~43% of the total Karakoram glacierised area. Active phases range from some...
Assessing climate-driven impacts on Karakoram glacier surge: A ...
2024年8月30日 · Glacial Lake Outburst Floods (GLOFs) have emerged as a significant phenomenon in Northern Pakistan's Karakoram, Himalayan, and Hindukush (HKH) mountain ranges. The accelerated melting of glaciers, driven by rising temperatures has led to the formation of 3,044 glacial lakes in the region from 2001 to 2013 [1].
Glaciohydrology of the Himalaya-Karakoram | Science - AAAS
Recent efforts to map and measure glacier extents, mass balance, and velocity, as well as the growth of glacial lakes, have filled several major gaps in glaciohydrology that existed a decade ago. This progress has been achieved primarily through remote sensing and modeling, yet field-based studies remain limited.
Characterizing the surge behaviour and associated ice-dammed lake ...
2023年7月18日 · Most recently (2018–2019) the Shispare Glacier in the central Karakoram surged, forming an ice-dammed lake (Rashid et al., 2020). The lake partially drained in June 2019 and then again in May 2020, affecting the Karakoram Highway and the neighbouring village of Hasanabad (Bhambri et al., 2020).
