Rock glaciers on the run – understanding rock glacier landform evolution and recent changes from numerical flow modeling [PDF]
The Cryosphere, 2016 . Rock glaciers are landforms that form as a result of creeping mountain permafrost which have received considerable attention concerning their dynamical and thermal changes.

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.

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 ...

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 ...

Mass balance and hydrological modeling of the Hardangerjøkulen ice cap in south-central Norway [PDF]
Hydrology and Earth System Sciences, 2021 A detailed, physically based, one dimensional column snowpack model (Crocus) has been incorporated into the hydrological model, Weather Research and Forecasting (WRF)-Hydro, to allow for direct surface mass balance simulation of glaciers and subsequent ...

Journal of Glaciology, 2022 Upernavik Isstrøm, a marine glacier undergoing rapid retreat, is simulated by forcing a numerical model with ocean-driven melt. A review of processes driving retreat led us to hypothesize that a glacier undergoing rapid retreat may be less sensitive to ...
