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 ...

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

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

Brief communication: Heterogenous thinning and subglacial lake activity on Thwaites Glacier, West Antarctica [PDF]
The Cryosphere, 2020 A system of subglacial lakes drained on Thwaites Glacier from 2012–2014. To improve coverage for subsequent drainage events, we extended the elevation and ice-velocity time series on Thwaites Glacier through austral winter 2019.

Transient evolution of basal drag during glacier slip
Journal of Glaciology, 2022 Glacier slip is usually described using steady-state sliding laws that relate drag, slip velocity and effective pressure, but where subglacial conditions vary rapidly transient effects may influence slip dynamics.

A unified model for transient subglacial water pressure and basal sliding
Journal of Glaciology, 2022 Changes in water pressure at the beds of glaciers greatly modify their sliding rate, affecting rates of ice mass loss and sea level change. However, there is still no agreement about the physics of subglacial sliding or how water affects it.

HydrologyArctic tidewater glaciers are retreating, serving as key indicators of global warming. This study aims to assess how subglacial hydrology affects glacier front retreat by comparing two glacier–fjord models of the Hansbreen glacier: one incorporating a ...

Technical note: Representing glacier geometry changes in a semi-distributed hydrological model [PDF]
Hydrology and Earth System Sciences, 2018 Glaciers play an important role in high-mountain hydrology. While changing glacier areas are considered of highest importance for the understanding of future changes in runoff, glaciers are often only poorly represented in hydrological models.

Subsurface hydrology of an overdeepened cirque glacier [PDF]
Journal of Glaciology, 2011 AbstractTo investigate the subsurface hydrological characteristics of an overdeepened cirque glacier, nine boreholes were drilled to the bed of West Washmawapta Glacier, British Columbia, Canada, in summer 2007. All holes were surveyed with a video camera, and four were subsequently instrumented with a combination of pressure transducers, thermistors ...

The contribution of glacier melt to streamflow
Environmental Research Letters, 2012 Ongoing and projected future changes in glacier volume and extent globally have led to concerns about the implications for water supplies. Glacier contributions to river discharge are not well known on a regional or global basis, nor are the populations ...
