Modeling Subglacial Hydrology in the Himalayas
The snowpack and glaciers of the Himalaya-Karakoram range feed several major river systems in Asia which provide water to over a billion people. Glacial retreat, glacial lake outburst flooding (GLOFs), surge behavior, and glacial ice mass balance are all

Coupling subglacial hydrology to basal friction in an Antarctic ice sheet model
, 2020 Due to the lack of direct observations, subglacial hydrology is still marginally considered in Antarctic ice sheet modelling studies, albeit that several approaches exist (e.g. LeBrocq, Bueler and Van Pelt).

Influence of water extraction on subglacial hydrology and glacier velocity
Abstract. Subglacial water modulates glacier velocity across a wide range of space and time scales by influencing friction at the glacier bed. Observations show ice acceleration due to supraglacial lake drainage and water draining through moulins, where both configurations involve water inputs to the bed.

SUBGLACIAL CONTROLS ON ANTARCTIC ICE SHEET DYNAMICS: Focus on subglacial hydrology and bed rheology [PDF]
Centered at the South Pole, Antarctica constitutes the largest expanse of continental ice on Earth, representingthe most significant freshwater stock. This mass of ice is in constant motion, deforming underthe influence of gravity and sliding over the bedrock on which it is lying.

The influence of subglacial hydrology on Antarctic ice sheet dynamics
, 2019 Current observed mass loss of the Antarctic ice sheet is tightly linked to the loss of buttressing of ice shelves, leading to increased inland mass flux and concomitant grounding-line retreat.

Modeling the Influence of Moulin Shape on Subglacial Hydrology
Journal of Geophysical Research F: Earth Surface, 2022AbstractSubglacial models represent moulins as cylinders or cones, but field observations suggest that the upper part of moulins in the Greenland Ice Sheet has more complex shapes. These more complex shapes should cause englacial water storage within moulins to vary as a function of depth, a relationship not currently accounted for in models.
