SHAKTI: Subglacial Hydrology and Kinetic, Transient Interactions v1.0 [PDF]
Geoscientific Model Development, 2018 Subglacial hydrology has a strong influence on glacier and ice sheet dynamics, particularly through the dependence of sliding velocity on subglacial water pressure.

Subglacial lakes and hydrology across the Ellsworth Subglacial Highlands, West Antarctica [PDF]
The Cryosphere, 2020 Subglacial water plays an important role in ice sheet dynamics and stability. Subglacial lakes are often located at the onset of ice streams and have been hypothesised to enhance ice flow downstream by lubricating the ice–bed interface.

A double continuum hydrological model for glacier applications [PDF]
The Cryosphere, 2014 The flow of glaciers and ice streams is strongly influenced by the presence of water at the interface between ice and bed. In this paper, a hydrological model evaluating the subglacial water pressure is developed with the final aim of ...

SHMIP The subglacial hydrology model intercomparison Project [PDF]
Journal of Glaciology, 2018 Subglacial hydrology plays a key role in many glaciological processes, including ice dynamics via the modulation of basal sliding. Owing to the lack of an overarching theory, however, a variety of model approximations exist to represent the subglacial ...

Incorporating modelled subglacial hydrology into inversions for basal drag [PDF]
The Cryosphere, 2017 A key challenge in modelling coupled ice-flow–subglacial hydrology is initializing the state and parameters of the system. We address this problem by presenting a workflow for initializing these values at the start of a summer melt season.

SUHMO: an adaptive mesh refinement SUbglacial Hydrology MOdel v1.0 [PDF]
Geoscientific Model Development, 2023 Water flowing under ice sheets and glaciers can have a strong influence on ice dynamics, particularly through pressure changes, suggesting that a comprehensive ice sheet model should include the effect of basal hydrology.

Antarctic Wide Subglacial Hydrology Modeling
Geophysical Research LettersGlobal sea levels are rising due, in large part, to the increase in the rate of melting of ice sheets as a direct result of climate change. A large fraction of uncertainty in future sea level rise comes from limited understanding of basal conditions ...

Subglacial hydrology regulates oscillations in marine ice streams [PDF]
The CryosphereMarine ice stream dynamics are sensitive to conditions at the grounding line and basal shear stress. Variations in subglacial hydrology have been implicated in ice stream speed-up and shutdown.

Simulating seasonal evolution of subglacial hydrology at a surging glacier in the Karakoram
Journal of GlaciologyGlacier motion, retreat and glacier hazards such as surges and glacial lake outburst floods (GLOFs) are likely underpinned by subglacial hydrology. Recent advances in subglacial hydrological modeling allow us to shed light on subglacial processes that ...

Annals of Glaciology, 2022 Subglacial hydrology is an important component of the ice dynamic system in Antarctica but is challenging to investigate due to the large spatial scales of the catchment systems, the ice thickness, and remote location.
