Quantifying the contribution of glacier runoff to streamflow in the upper Columbia River Basin, Canada [PDF]
Hydrology and Earth System Sciences, 2012 Glacier melt provides important contributions to streamflow in many mountainous regions. Hydrologic model calibration in glacier-fed catchments is difficult because errors in modelling snow accumulation can be offset by compensating errors in glacier ...

Calibration of glacier volume–area relations from surface extent fluctuations and application to future glacier change [PDF]
Journal of Glaciology, 2010 AbstractThe volume- and area-change evolution of glaciers can be obtained by employing the volume–area scaling approach during mass-balance modelling. This method usually requires information on the initial surface area and ice volume to adjust the volume–area relation to the specific ice body.

Frontiers in Earth Science, 2019 Himalayan glaciers are a storehouse of fresh water and play a significant role in influencing the runoff through numerous perennial rivers flowing over the Indo-Gangetic plains, providing freshwater to the second largest populated country in the world ...

Glacier Retreat in Eastern Himalaya Drives Catastrophic Glacier Hazard Chain
Geophysical Research LettersCryospheric responses to climate warming include glacier retreat, altitude‐dependent thermal instability, and abundant meltwater, which increase the frequency of catastrophic glacier hazard chain (CGHC) events.

Glacier volume estimation as an ill-posed boundary value problem [PDF]
, 2012 . Estimating a glacier's volume by inferring properties at depth from properties observed at the surface creates an instability that grows exponentially with the size of the glacier.

The equilibrium flow and mass balance of the Taku Glacier, Alaska 1950–2006 [PDF]
The Cryosphere, 2008 The Taku Glacier, Alaska has advanced 7.5 km since the late nineteenth century, while all other primary outlet glaciers of the Juneau Icefield are in retreat.

Halving of Swiss glacier volume since 1931 observed from terrestrial image photogrammetry
The Cryosphere, 2022 . The monitoring of glaciers in Switzerland has a long tradition, yet glacier changes during the 20th century are only known through sparse observations.

Journal of Glaciology, 2023 The Northern and Southern Patagonian Icefields are rapidly losing volume, with current volume loss rates greater than 20 km3 a−1. However, details of the spatial and temporal distribution of their volume loss remain uncertain.

A Bayesian ice thickness estimation model for large-scale applications
Journal of Glaciology, 2020 Accurate estimations of ice thickness and volume are indispensable for ice flow modelling, hydrological forecasts and sea-level rise projections. We present a new ice thickness estimation model based on a mass-conserving forward model and a Bayesian ...

Volume–area scaling vs flowline modelling in glacier volume projections [PDF]
Annals of Glaciology, 2007 AbstractVolume–area scaling provides a practical alternative to ice-flow modelling to account for glacier size changes when modelling the future evolution of glaciers; however, uncertainties remain as to the validity of this approach under non-steady conditions.
