Impact of changes in climate and glacier configurations on runoff from the Langtang River basin, Nepal [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences
Climate 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 ...

Effects of undercutting and sliding on calving: a global approach applied to Kronebreen, Svalbard [PDF]

open access: yesThe 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

open access: yesAnnals of Glaciology, 2022
A comparison of major ion chemistry of subglacial boreholes and discharging subglacial waters reveals three fundamentally different glacier hydrochemical regimes.

Assessing the influence of the Merzbacher Lake outburst floods on discharge using the hydrological model SWIM in the Aksu headwaters, Kyrgyzstan/NW China [PDF]

open access: yes, 2013
Glacial lake outburst floods (GLOF) often have a significant impact on downstream users. Including their effects in hydrological models, identifying past occurrences and assessing their potential impacts are challenges for hydrologists working in ...

A semi-automated, GIS-based framework for the mapping of supraglacial hydrology

open access: yesJournal 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]

open access: yesThe 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-

Estimating the characteristics of runoff inflow into Lake Gojal in ungauged, highly glacierized upper Hunza River Basin, Pakistan [PDF]

open access: yes, 2013
Motivated by the potential flood outburst of Lake Gojal in the ungauged highly glacierized (27%) upper Hunza River Basin (HRB) in Pakistan that was dammed by a massive landslide on 4 January 2010, we attempt to analyze the characteristics of water inflow

Composite suspended sediment particles and flocculation in glacial meltwaters: preliminary evidence from Alpine and Himalayan basins [PDF]

open access: yes, 2002
Research over the last decade has shown that the suspended sediment loads of many rivers are dominated by composite particles. These particles are also known as aggregates or flocs, and are commonly made up of constituent mineral particles, which ...

Near-margin ice thickness and subglacial water routing, Leverett Glacier, Greenland

open access: yesArctic, Antarctic, and Alpine Research, 2018
Ice thickness measurements near the margin of the Greenland Ice Sheet (GrIS) are relatively sparse, presenting issues for modeling ice-flow dynamics, ice-sheet change, and subglacial hydrology.

Worldwide version-controlled database of glacier thickness observations [PDF]

open access: yesEarth System Science Data, 2020
Although worldwide inventories of glacier area have been coordinated internationally for several decades, a similar effort for glacier ice thicknesses was only initiated in 2013.
