Modeling the effect of glacier recession on streamflow response using a coupled glacio-hydrological model [PDF]
Hydrology and Earth System Sciences, 2014 We describe an integrated spatially distributed hydrologic and glacier dynamic model, and use it to investigate the effect of glacier recession on streamflow variations for the upper Bow River basin, a tributary of the South Saskatchewan River, Alberta ...

Mutual effects of ablation and ice temperature in a firn-free glacier: Observations from Aug 1st glacier on northeast Tibetan plateau [PDF]
iScienceSummary: Glacier stability depends on the interaction between ice temperature and ablation, processes mediated by firn cover. Although firn-covered glaciers have been extensively investigated, firn-free glacier dynamics remain less clear.

Assessing glacier changes and hydrological impacts in the upper Indus Basin under CMIP6 climate scenarios [PDF]
iScienceSummary: Glaciers in the Himalaya are vital for sustaining streamflow in the Upper Indus Basin. This study quantifies future glacier mass and area changes in the Jhelum sub-basin using projections from 13 bias-corrected CMIP6 climate models under SSP245 ...

Inferring time-dependent calving dynamics at Helheim Glacier
Journal of Glaciology, 2023 We perform Bayesian inference of the parameters of a time-dependent model of ice flow and calving at Helheim Glacier, East Greenland. We find that, while a time-independent calving parameterization can recover the mean observed terminus position, such a ...

Performance analysis of high-resolution ice-sheet simulations
Journal of Glaciology, 2023 Numerical glacier and ice-sheet models compute evolving ice geometry and velocity fields using various stress-balance approximations and boundary conditions. At high spatial resolution, with horizontal mesh/grid resolutions of a few kilometers or smaller,

Identification of glacial meltwater runoff in a karstic environment and its implication for present and future water availability [PDF]
Hydrology and Earth System Sciences, 2013 Glaciers all over the world are expected to continue to retreat due to the global warming throughout the 21st century. Consequently, future seasonal water availability might become scarce once glacier areas have declined below a certain threshold ...

Numerical modeling of the dynamics of the Mer de Glace glacier, French Alps: comparison with past observations and forecasting of near-future evolution [PDF]
The Cryosphere, 2020 Alpine glaciers are shrinking and rapidly loosing mass in a warming climate. Glacier modeling is required to assess the future consequences of these retreats on water resources, the hydropower industry and risk management.

Simulation, modeling and authoring of glaciers [PDF]
ACM Transactions on Graphics, 2020 Glaciers are some of the most visually arresting and scenic elements of cold regions and high mountain landscapes. Although snow-covered terrains have previously received attention in computer graphics, simulating the temporal evolution of glaciers as well as modeling their wide range of features has never been addressed.

Quasi-static granular flow of ice mélange [PDF]
, 2018 We use Landsat 8 imagery to generate ice mélange velocity fields at Greenland’s three most productive outlet glaciers: Jakobshavn Isbræ, Helheim Glacier, and Kangerdlugssuaq Glacier.

Toward Numerical Modeling of Interactions Between Ice-Marginal Proglacial Lakes and Glaciers
Frontiers in Earth Science, 2020 Global climate change is evidently manifest in disappearing mountain glaciers and receding and thinning ice sheet margins. Concern about contemporaneous proglacial lake development has spurred an emerging area of research seeking to quantitatively ...
