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.

Laboratory Models of Glacier Dynamics
Geological Society of America Bulletin, 1972Excellent laboratory models of glaciers were produced by pouring a mixture of molding plaster and water down a prefashioned trough of nonabsorbent material. The plaster models simulate the dynamics of glacier flow and accurately display many surface and internal structures common to real glaciers, including crevasse and flow patterns, icefalls and ...

Modelling of Glacier Mass Balance
1993The energy balance of the ice/snow surface is the dominating factor with regard to mass balance of glaciers in warm environments (currently all ice outside Antarctica). It is shown that an energy balance model is able to generate realistic mass-balance profiles from climate data for glaciers in widely differing climatic settings.
