Understanding jökulhlaups: From tale to theory

, 2010
The study of jökulhlaups has advanced from describing them qualitatively to measuring systematically on site their discharge curves and source geometry, as well as investigating conditions when particular floods were initiated.

Hydrologic and geomorphic effects of temporary ice-dammed lake formation during jökulhlaups

, 2003
Glacial outburst floods (jökulhlaups) occur frequently in glaciated environments, and the resultant flooding causes geomorphic change and, in some instances, damage to local infrastructure.

Glacial lake formation and evolution in the Hindukush Region of Afghanistan between 1990 and 2020

The rapid retreat of mountain glaciers and the formation of new glacial lakes due to climate change pose considerable risks in mountain regions, especially where they increase the frequency and magnitude of glacial-lake outburst floods (GLOFs) and ...

Jökulhlaups in Iceland : sources, release and drainage

, 2010
Jökulhlaups in Iceland may originate from marginal or subglacial sources of water melted by atmospheric processes, permanent geothermal heat or volcanic eruptions.

Evolutionary model for glacial lake-outburst fans at the ice-sheet front : Development of meltwater outlets and origins of bedforms [PDF]

Large-scale landforms originated from jökulhlaups or glacial lake-outburst floods (GLOFs), and their small-scale components help in recognising the sedimentary environment of the flood.

Icelandic jökulhlaup impacts: Implications for ice-sheet hydrology, sediment transfer and geomorphology

, 2006
Glaciers and ice sheets erode, entrain, and deposit massive quantities of debris. Fluxes of subglacial meltwater exert a fundamental control on ice dynamics and sediment transport budgets.

Reconstruction of Consecutive GLOFs from Small Proglacial Lake in Central Himalayas

Glacial lake outburst floods (GLOFs) is a major glacial hazard, occurring when a vast amount of water is suddenly released from a naturally dammed proglacial lake due to overtopping or dam breaching.

Recent occurrence of large jökulhlaups at Lake Tuborg, Ellesmere Island, Nunavut.

, 2009
The varved sediment record from glacially-fed Lake Tuborg, Ellesmere Island, Nunavut, shows that only three large jökulhlaups have occurred there in the last millennium: 2003, 1993, and 1960. Detailed analyses of sediment microstructure and particle size,

Glacial Lake Outburst Flood Risk in the Poiqu/Bhote Koshi/Sun Koshi River Basin in the Central Himalayas

, 2015
The Himalayas have experienced several glacial lake outburst floods (GLOFs), and the risk of GLOFs is now increasing in the context of global warming.
