Impact of changes in climate and glacier configurations on runoff from the Langtang River basin, Nepal [PDF]
Proceedings of the International Association of Hydrological SciencesClimate change is rapidly altering Himalayan glaciers, jeopardizing downstream water resources. This study investigates the impact of changing air temperatures, precipitation, and glacier configurations on streamflow in the Langtang River basin, a vital ...

Basal conditions of Denman Glacier from glacier hydrology and ice dynamics modeling [PDF]
The Cryosphere, 2023 Basal sliding in Antarctic glaciers is often modeled using a friction law that relates basal shear stresses to the effective pressure. As few ice sheet models are dynamically coupled to subglacial hydrology models, variability in subglacial hydrology ...

Snow and glacier hydrology [PDF]
Eos, Transactions American Geophysical Union, 2001 The study of snow and ice is rich in both fundamental science and practical applications. Snow and Glacier Hydrology offers something for everyone, from resource practitioners in regions where water supply depends on seasonal snow pack or glaciers, to research scientists seeking to understand the role of the solid phase in the water cycle and climate ...

Spectral roughness of glaciated bedrock geomorphic surfaces: Implications for glacier sliding [PDF]
, 2000 A microroughness meter (MRM) was used to measure the high-frequency roughness of a number of geomorphic surfaces in the forefield of Glacier de Tsanfleuron, Switzerland.

Effects of undercutting and sliding on calving: a global approach applied to Kronebreen, Svalbard [PDF]
The Cryosphere, 2018 In this paper, we study the effects of basal friction, sub-aqueous undercutting and glacier geometry on the calving process by combining six different models in an offline-coupled workflow: a continuum–mechanical ice flow model (Elmer/Ice), a climatic

Geological and glacial-hydrologic controls on chemical weathering in the subglacial environment
Annals of Glaciology, 2022 A comparison of major ion chemistry of subglacial boreholes and discharging subglacial waters reveals three fundamentally different glacier hydrochemical regimes.

A semi-automated, GIS-based framework for the mapping of supraglacial hydrology
Journal of Glaciology, 2023 Supraglacial drainage networks play an integral role in both glacier dynamics and run-off timing, and mapping them provides insight into their role in glacial systems.

Quantification of seasonal and diurnal dynamics of subglacial channels using seismic observations on an Alpine glacier [PDF]
The Cryosphere, 2020 Water flowing below glaciers exerts a major control on glacier basal sliding. However, our knowledge of the physics of subglacial hydrology and its link with sliding is limited because of lacking observations. Here we use a 2-year-long dataset made of on-

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]
, 2012 Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.
