Inversion of a glacier hydrology model [PDF]
Annals of Glaciology, 2016 The subglacial hydrologic system exerts strong controls on the dynamics of the overlying ice, yet the parameters that govern the evolution of this system are not widely known or observable.

POLYTHERMAL GLACIER HYDROLOGY: A REVIEW [PDF]
Reviews of Geophysics, 2011 The manner by which meltwater drains through a glacier is critical to ice dynamics, runoff characteristics, and water quality. However, much of the contemporary knowledge relating to glacier hydrology has been based upon, and conditioned by, understanding gleaned from temperate valley glaciers.

Basal conditions of Denman Glacier from glacier hydrology and ice dynamics modeling [PDF]
The Cryosphere, 2023 Basal sliding in Antarctic glaciers is often modeled using a friction law that relates basal shear stresses to the effective pressure. As few ice sheet models are dynamically coupled to subglacial hydrology models, variability in subglacial hydrology ...

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 ...

Sensitivity of subglacial drainage to water supply distribution at the Kongsfjord basin, Svalbard [PDF]
The Cryosphere, 2021 By regulating the amount, the timing, and the location of meltwater supply to the glacier bed, supraglacial hydrology potentially exerts a major control on the evolution of the subglacial drainage system, which in turn modulates ice velocity.

Persistent, extensive channelized drainage modeled beneath Thwaites Glacier, West Antarctica [PDF]
The Cryosphere, 2022 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 systems that lead to low effective pressures.

Seasonal Acceleration of Petermann Glacier, Greenland, From Changes in Subglacial Hydrology
Geophysical Research Letters, 2023 Petermann Glacier is a major outlet glacier of northern Greenland that drains a marine‐based basin vulnerable to destabilization from enhanced oceanic and atmospheric forcings. Using satellite radar interferometry data from the Sentinel‐1a/b missions, we

Canadian Glacier Hydrology, 2003-2007 [PDF]
Canadian Water Resources Journal, 2009 Glacier hydrological research in Canada from 2002-2007 continues to advance, driven by new observations of glacier retreat in all regions of the country. New observation networks have been formed to study various aspects of glacier change and linkages with the hydrological system.
