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.

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.

Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal [PDF]
, 2015 In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.

Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]
, 2005 This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

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.

An energy-balance model for debris-covered glaciers including heat conduction through the debris layer [PDF]
, 2010 Extensive covers of supraglacial debris are often present in glacier ablation areas, and it is essential to assess exactly how the debris affects glacier melt rates.

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 ...

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.
