Modelling Debris-Covered Glacier Ablation Using the Simultaneous Heat and Water Transport Model. Part 1: Model Development and Application to North Changri Nup

Frontiers in Earth Science, 2022
Modelling ablation of glacier ice under a layer of mineral debris is increasingly important, because the extent of supraglacial debris is expanding worldwide due to glacier recession.

Representing moisture fluxes and phase changes in glacier debris cover using a reservoir approach [PDF]

, 2014
Due to the complexity of treating moisture in supraglacial debris, surface energy balance models to date have neglected moisture infiltration and phase changes in the debris layer.

An energy-balance model for debris-covered glaciers including heat conduction through the debris layer [PDF]

, 2010
Extensive covers of supraglacial debris are often present in glacier ablation areas, and it is essential to assess exactly how the debris affects glacier melt rates.

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]

, 2008
Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

Meteorology and surface energy fluxes in the 2005–2007 ablation seasons at the Miage debris-covered glacier, Mont Blanc Massif, Italian Alps [PDF]

, 2010
During the 2005–2007 June–September ablation seasons, meteorological conditions were recorded on the lower and upper parts of the debris‐covered ablation zone of Miage Glacier, Italy. In 2005, debris temperature and subdebris ice melt were also monitored

Air temperature distribution and energy balance modelling of a debris-covered glacier [PDF]

, 2016
Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.

Ice cliff contribution to the tongue-wide ablation of Changri Nup Glacier, Nepal, central Himalaya [PDF]

The Cryosphere, 2018
Ice cliff backwasting on debris-covered glaciers is recognized as an important mass-loss process that is potentially responsible for the debris-cover anomaly, i.e.

Remotely sensed debris thickness mapping of Bara Shigri Glacier, Indian Himalaya [PDF]

, 2015
Despite the important role of supraglacial debris in ablation, knowledge of debris thickness on Himalayan glaciers is sparse. A recently developed method based on reanalysis data and thermal band satellite imagery has proved to be potentially suitable ...

Southwest-facing slopes control the formation of debris-covered glaciers in the Bhutan Himalaya [PDF]

The Cryosphere, 2013
To understand the formation conditions of debris-covered glaciers, we examined the dimension and shape of debris-covered areas and potential debris-supply (PDS) slopes of 213 glaciers in the Bhutan Himalaya.

Assessing ice-cliff backwasting and its contribution to total ablation of debris-covered Miage glacier, Mont Blanc massif, Italy [PDF]

, 2014
Continuous surface debris cover strongly reduces the ablation of glaciers, but high melt rates may occur at ice cliffs that are too steep to hold debris.
