Validation of effective subglacial hydrology models

The presence of subglacial lubrication networks at the ice-bed interface is a key component for ice sheet dynamics. A subglacial network has the potential to facilitate rapid ice flow through reduction in basal friction, possibly resulting in the formation of surges and ice streams.

Modeling Subglacial Hydrology in the Himalayas

2023
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 likely strongly affected by subglacial hydrology.

Subglacial meltwater corridors and their relationship to the soft-bed subglacial hydrological continuum

The subglacial environment is a key part of glacier dynamics, and the ‘slipperiness’ of the bed has shown to be related to the rate of sea level rise. Investigations of the subglacial hydrological system associated with soft beds are rare.

A numerical study of hydrologically driven glacier dynamics and subglacial flooding

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
A hydrologically coupled flowband model of ‘higher order’ ice dynamics is used to explore perturbations in response to supraglacial water drainage and subglacial flooding. The subglacial drainage system includes interacting ‘fast’ and ‘slow’ drainage elements. The fast drainage system is assumed to be composed of ice-walled conduits and the slow system

Emulating a Subglacial Hydrology Model with a Neural Operator

Subglacial hydrology exerts an important control on ice flow and influences the evolution of downstream hydrology, as well as the occurrence of glacial lake outburst floods. However, large-scale modelling of subglacial hydrology remains computationally expensive due to the presence of nonlinear processes.Within our DeLIGHT (Deep-Learning-Informed ...
