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.

Ice-Dynamical Glacier Evolution Modeling—A Review
Reviews of Geophysics, 2022 AbstractGlaciers play a crucial role in the Earth System: they are important water suppliers to lower‐lying areas during hot and dry periods, and they are major contributors to the observed present‐day sea‐level rise. Glaciers can also act as a source of natural hazards and have a major touristic value.

Modeling 2 m Air Temperatures Over Mountain Glaciers: Exploring the Influence of Katabatic Cooling and External Warming [PDF]
Journal of Geophysical Research D: Atmospheres, 2015 Air temperature is one of the most relevant input variables for snow and ice melt calculations. However, local meteorological conditions, complex topography, and logistical concerns in glacierized regions make the measuring and modeling of air ...

Modeling Periodically Surging Glaciers
Science, 1974A numerical model has been developed which produces periodic surging as a characteristic of some glaciers for a certain accumulation and bedrock distribution in contrast to the normal steady state for nonsurging glaciers. Results are presented to illustrate how the magnitude of changes in the length, thickness, and velocity of surging glaciers can be ...

Evolution of rock glaciers and alpine glaciers: A model–model approach
2003The effects of horizontal stress transmission on the transient evolution of non-linear viscous bodies having aspects ratios similar to active alpine rock glaciers is investigated. This is done through a comparison between a shallow-ice model, which predicts material flux to be a local function of thickness and slope, and a finite-element model, which ...

Glacier Fluctuations and Simple Glacier Models
2020This chapter details the formulation and analysis of simple mathematical models that describe the response of glaciers to mass balance changes. The primary focus is on glacier length fluctuations. Key aspects studied include the response time and sensitivity of different glaciers to changes in climate, and the use of models to reconstruct past ...

A model for the flow of rock glaciers
International Journal of Non-Linear Mechanics, 2013Abstract A constitutive model is developed for describing the response of rock glaciers that takes into account the effect of the shear rate, pressure and the volume fraction of the rocks and sand grains trapped within the interstices of the rock glacier on the viscosity of the rock glacier.

As a geophysical fluid dynamics phenomenon, glacier motion has features in common with some of the other terrestrial and planetary flows considered in this book, but it also has a number of special features that give it a character of its own. It can be compared to mantle flow and convection: both involve slow flow of essentially incompressible fluids ...

The wording term “glacier modeling” is used in a generic sense for describing numerical simulations of glaciers and glacier related processes. Glacier modeling activities can be subdivided into four main branches reflecting the interactions between glaciers and other compartments of the earth system.
