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 ...

Recent hydrological response of glaciers in the Canadian Rockies to changing climate and glacier configuration [PDF]
Hydrology and Earth System Sciences, 2022 Mountain snow and ice greatly influence the hydrological cycle of alpine regions by regulating both the quantity of and seasonal variations in water availability downstream.

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.

Hydrology of Tidal Waters at the Glacier Terminus and their Impact on Hydrographical Surveys and Navigation Safety [PDF]
TransNav, 2020 The data analysed in the paper are related to the hydrology of tidal waters at a tidewater glacier terminus. Set of data was collected in the wide span of time from 2009 till 2015 in the Nordaustlandet and Southwest Spitsbergen near various tidal ...

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

Sedimentary Signatures of Persistent Subglacial Meltwater Drainage From Thwaites Glacier, Antarctica
Frontiers in Earth Science, 2022 Subglacial meltwater drainage can enhance localized melting along grounding zones and beneath the ice shelves of marine-terminating glaciers. Efforts to constrain the evolution of subglacial hydrology and the resulting influence on ice stability in space

Implementation of a process-based catchment model in a poorly gauged, highly glacierized Himalayan headwater [PDF]
Hydrology and Earth System Sciences, 2007 The paper presents a catchment modeling approach for remote glacierized Himalayan catchments. The distributed catchment model TACD, which is widely based on the HBV model, was further developed for the application in highly glacierized catchments on a ...

Journal of Glaciology, 2022 We present the first fully coupled 3D full-Stokes model of a tidewater glacier, incorporating ice flow, subglacial hydrology, plume-induced frontal melting and calving. We apply the model to Store Glacier (Sermeq Kujalleq) in west Greenland to simulate a
