Flood events caused by discharge from Qaanaaq Glacier, northwestern Greenland

open access: yesJournal of Glaciology, 2021
As a result of climate warming, glacial meltwater discharge has been increasing in Greenland. During the summers of 2015 and 2016, there were rapid increases in discharge from Qaanaaq Glacier in northwestern Greenland. These discharges resulted in floods

Influence of subglacial drainage system evolution on glacier surface motion: Haut Glacier d'Arolla, Switzerland [PDF]

open access: yes, 2002
The relationship between the evolution of subglacial drainage system morphology and spatial patterns of glacier surface velocity was investigated using dye tracing experiments and ground surveying throughout the 1995 melt season at Haut Glacier d'Arolla,

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]

open access: yes, 2012
Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

Progress and prospect in risk assessment of hazards from glacier lake outbursts

open access: yesShui kexue jinzhan, 2012
Glacier Lake Outburst Floods(GLOF) are natural hazards to the socioeconomic system in hazard regions.However,their predictions still remain worldwide challenge,and thus have attracted much attention in the scientific community as well as society at large.

Sustained retreat of the Pine Island Glacier [PDF]

open access: yes, 2013
We use satellite observations to show that, between 1992 and 2011, the Pine Island Glacier hinge line retreated at a rate of 0.95 ± 0.09 km yr−1 despite a progressive steepening and shoaling of the glacier surface and bedrock slopes, respectively, which ...

The 24 July 2008 outburst flood at the western Zyndan glacier lake and recent regional changes in glacier lakes of the Teskey Ala-Too range, Tien Shan, Kyrgyzstan [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2010
On 24 July 2008, a glacier lake outburst flood (GLOF) occurred at the western (w-) Zyndan glacier lake in the Tong District of Ysyk-Köl Oblast, Kyrgyzstan.

Hazard from Himalayan glacier lake outburst floods [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Sustained glacier melt in the Himalayas has gradually spawned more than 5,000 glacier lakes that are dammed by potentially unstable moraines. When such dams break, glacier lake outburst floods (GLOFs) can cause catastrophic societal and geomorphic impacts.

GIS based landslide susceptibility mapping of northern areas of Pakistan, a case study of Shigar and Shyok Basins

open access: yesGeomatics, Natural Hazards & Risk, 2017
This study presents the use of geographical information system (GIS) datasets and methods to investigate landslide susceptibility in the rugged mountainous terrain of Shigar and Shyok Basins in northern areas of Pakistan.

Landslide-generated tsunami and particle transport in mountain lakes and reservoirs

open access: yesAnnals of Glaciology, 2016
Gravitational mass flows may generate tsunamis as they hit water bodies such as oceans, reservoirs or mountain lakes. Upon impact, they can generate tremendous particle-laden or debris flows and floods.

Radio-echo soundings on Icelandic temperate glaciers: history of techniques and findings

open access: yesAnnals of Glaciology, 2020
Since the mid-1970s radio-echo soundings have been conducted on Iceland's temperate glaciers. Since then, low-frequency radar technology has furthered the study of most of the island's ice caps.
