Recent observations of dynamic water systems beneath the Greenland and Antarctic ice
sheets have sparked renewed interest in modelling subglacial drainage. The foundations of …

We present a two‐dimensional Glacier Drainage System model (GlaDS) that couples
distributed and channelized subglacial water flow. Distributed flow occurs through linked …

When large volumes of meltwater arrive suddenly at the glacier bed, the capacity of
subglacial conduits is exceeded, generating transiently high fluid pressures. Yet we …

A numerical model is used to calculate how the motion of an idealized ice-sheet margin is
affected by the subglacial drainage of melt water from its surface. The model describes the …

Subglacial hydrology is a leading control on basal friction and the dynamics of glaciers and
ice sheets. At low discharge, subglacial water flows through high-pressure, sheet-like …

Penetration of surface meltwater to the bed of the Greenland Ice Sheet each summer causes
an initial increase in ice speed due to elevated basal water pressure, followed by slowdown …

The subglacial drainage system is one of the main controls on basal sliding, but remains
only partially understood. Here we use an 8-year dataset of borehole observations on a …

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 …

Major uncertainties in the response of ice sheets to environmental forcing are due to
subglacial processes. These processes pertain to the type of sliding or friction law as well as …

Below hard‐bedded glaciers, both basal friction and distributed subglacial drainage are
thought to be controlled by a network of cavities. Previous coupled hydro‐mechanical …
