Debris-covered glaciers are characterised by a mantle of rock material, the supraglacial debris, spread over part of the ablation zone. The debris material origins from the catchment above and the bedrock below the glacier and appears at the glacier surface in the ablation zone.

The role of glacier structures in the degradation of debris-covered glaciers.
2023Glaciers in High Mountain Asia (HMA) are in a state of rapid decline, attributed to climatic changes at an intra-regional scale. Mass loss from glaciers in the region occurs in the form of the thinning and recession of glacier tongues, formation and coalescence of supraglacial ponds, and a growth in the size and number of glacial lakes, leading to a ...

Do Debris-Covered Glaciers Demonstrate Distinctive Hydrological Behaviour Compared to Clean Glaciers? [PDF]
Journal of Hydrology, 2019 Supraglacial debris is known to strongly influence the distribution of glacier surface melt. Since melt inputs drive the formation and evolution of glacial drainage systems, it should follow that the drainage systems of debris-covered glaciers will ...

Modelling debris-covered glacier melt
2023Meltwater from glaciers contributes to hydro-electricity and agricultural production in some places, and model predictions of glacier melt can inform water management decisions. However, predictions are inherently uncertain. Accurately constrained uncertainty can be key to success of management decisions.

Debris thickness patterns on debris-covered glaciers
Geomorphology, 2018Abstract Many debris-covered glaciers have broadly similar debris thickness patterns: surface debris thickens and tends to transition from convex- to concave-up-down glacier. We explain this pattern using theory (analytical and numerical models) paired with empirical observations.

Debris cover and the thinning of Kennicott Glacier, Alaska
2021<p>Many glaciers in High Mountain Asia are experiencing the debris-cover anomaly. The Kennicott Glacier, a large Alaskan Glacier, is also thinning most rapidly under debris cover. This contradiction has been explained by melt hotspots, such as ice cliffs, streams, or ponds scattered within the debris cover or by declining ice flow in time.

The geomorphology of debris-covered Ponkar Glacier, Nepal
2020<p>Understanding the evolution of debris-covered glaciers in High Mountain Asia is important for making informed projections of climate change impacts and associated water security and hazard-related issues. &#160;Here we describe the geomorphology of Ponkar Glacier, a debris-covered glacier in Nepal using high-resolution

<p>It is common for temperate glaciers in mountainous regions to exhibit an extensive ablation-zone supraglacial debris cover. Although secondary reworking of surface debris and its role in modifying rates of glacier melt is receiving increasing attention, debris origin and primary distribution is poorly understood. Arguably, studies have

DEBRIS-COVERED GLACIERS AND ROCK GLACIERS
2014The debris-covered glaciers are observed all over the glaciation regions of the world (Alps, Antarctica, Greenland, Ants, Cascades, Rocky Mountains and ext.). The debris covered glaciers are the formations which occur as a result of the recession of normal glaciers.

Remote SensingDebris-free and debris-covered glaciers are both extensively present in the southeastern Tibetan Plateau. High-precision and rigorous comparative observational studies on different types of glaciers help us to accurately understand the overall state of water resource variability and the underlying mechanisms.
