Abstract:
... Meltwater from the glaciers in High Mountain Asia plays a critical role in water availability and food security in central and southern Asia. However, observations of glacier ablation and accumulation rates are limited in spatial and temporal scale due to the challenges that are associated with fieldwork at the remote, high-altitude settings of these glaciers. Here, using a remote-sensing-based ma ...

Abstract:
... Most natural rock slope failures result from long-term strength degradation. It is often hypothesized that glacial retreat leads to enhanced progressive damage accumulation in adjacent rock slopes, due to mechanical unloading and changes to the thermal and hydraulic boundary conditions. However, direct observations of subsurface processes in a rock slope subject to glacial retreat are rare. In thi ...

Abstract:
... The hydrological characteristics of debris-covered glaciers are known to be fundamentally different from those of clean-ice glaciers, even within the same climatological, geological, and geomorphological setting. Understanding how these characteristics influence the timing and magnitude of meltwater discharge is particularly important for regions where downstream communities rely on this resource ...

Abstract:
... Understanding the generation mechanisms of floods is important to estimating future flood hazards by improving flood frequency analysis and flood trend interpretation. From the hydrological perspective of flood classification, flood types are determined by the seasonality or magnitudes of hydrological drivers (e.g., rainfall, snowmelt, catchment wetness). Few studies attribute floods to the causat ...

Abstract:
... Debris-covered glaciers receive increasing attention during the current period of sustained negative mass balance and expanding debris cover. The debris cover induces various feedback mechanisms that shape the evolution of the glacier geometry, and also the glacier surface. Although the surface morphology of many debris-covered glaciers is markedly different from that of debris-free glaciers, only ...

Abstract:
... Meltwater from glaciers is not only a stable source of water but also affects downstream streamflow dynamics. One of these dynamics is the interannual variability of streamflow. Glaciers can moderate streamflow variability because the runoff in the glacierized part, driven by temperature, correlates negatively with the runoff in the non‐glacierized part of a catchment, driven by precipitation, the ...
