Debris-cover impact on glacier melting in the Upper Indus Basin

, 2022
Out of 4530 glaciers covering ∼4770 km2 in the Upper Indus Basin, viz., Chenab, Zanaskar and Suru sub-basins, we selected topographically and morphologically homogeneous set of 98 glaciers; 56 debris-covered and 42 clean to assess the impact of debris ...

Meteorological impacts of a novel debris‐covered glacier category in a regional climate model across a Himalayan catchment

Atmospheric Science Letters, 2021
Many of the glaciers in the Nepalese Himalaya are partially covered in a layer of loose rock known as debris cover. In the Dudh Koshi River Basin, Nepal, approximately 25% of glaciers are debris‐covered.

Reduced melt on debris-covered glaciers: investigations from Changri Nup Glacier, Nepal [PDF]

The Cryosphere, 2016
Abstract. Debris-covered glaciers occupy more than 1/4 of the total glacierized area in the Everest region of Nepal, yet the surface mass balance of these glaciers has not been measured directly. In this study, ground-based measurements of surface elevation and ice depth are combined with terrestrial photogrammetry and unmanned aerial vehicle (UAV ...

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

, 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.

Three-Dimensional Time Series Movement of the Cuolangma Glaciers, Southern Tibet with Sentinel-1 Imagery

Remote Sensing, 2020
Many debris-covered glaciers are broadly distributed across High Mountain Asia and have made a number of contributions to water circulation for Qinghai-Tibet Plateau (QTP).

Debris-covered glacier energy balance model for Imja–Lhotse Shar Glacier in the Everest region of Nepal [PDF]

The Cryosphere, 2015
Debris thickness plays an important role in regulating ablation rates on debris-covered glaciers as well as controlling the likely size and location of supraglacial lakes.

Debris‐covered glaciers and rock glaciers in the nanga parbat himalaya, pakistan [PDF]

Geografiska Annaler: Series A, Physical Geography, 2000
The origin and mobilization of the extensive debris cover associated with the glaciers of the Nanga Parbat Himalaya is complex. In this paper we propose a mechanism by which glaciers can form rock glaciers through inefficiency of sediment transfer from glacier ice to meltwater.

Pluri-decadal (1955–2014) evolution of glacier–rock glacier transitional landforms in the central Andes of Chile (30–33° S) [PDF]

Earth Surface Dynamics, 2017
Three glacier–rock glacier transitional landforms in the central Andes of Chile are investigated over the last decades in order to highlight and question the significance of their landscape and flow dynamics.

Modelling climate sensitivity of debris-covered glaciers

, 2022
The common occurrence of debris-covered glaciers in high-mountain areas makes their response to climate change relevant. The insulating effect of debris cover on surface melt causes debris-covered glaciers behave differently from debris-free glaciers, warranting the use of a specialized model for predictions.
