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.

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.

The role of subglacial hydrology in ice streams with elevated geothermal heat flux [PDF]
Journal of Glaciology, 2020 The spatial distribution of geothermal heat flux (GHF) under ice sheets is largely unknown. Nonetheless, it is an important boundary condition in ice-sheet models, and suggested to control part of the complex surface velocity patterns observed in some ...

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.

Geophysical Research LettersTwo outstanding questions for the future of the Greenland Ice Sheet are (a) how enhanced meltwater draining beneath the ice will impact the behavior of large tidewater glaciers, and (b) to what extent tidewater glacier velocity is driven by changes at ...

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 ...

Subglacial Processes and Subglacial Hydrology
, 2016 The hydrology of glaciers is known to have a significant influence on glacier dynamics. Rapid variations in dynamics can occur due to changes in the glacial and subglacial hydrology. However, our understanding of the subglacial drainage system is based on few direct and usually short-term observations.

Surging of a Hudson Strait-scale ice stream: subglacial hydrology matters but the process details mostly do not [PDF]
The Cryosphere, 2023 While subglacial hydrology is known to play a role in glacial dynamics on sub-annual to decadal scales, it remains unclear whether subglacial hydrology plays a critical role in ice sheet evolution on centennial or longer timescales.
