Laboratory Models of Glacier Dynamics

Geological Society of America Bulletin, 1972
Excellent 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

1993
The 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.

Plastic Modelling of Glaciers and Outlets

1993
In reconstruction of past ice sheets a plastic approach is often used in order to get a quick estimate of the shape and thickness of an ice sheet. The basic in the model has been that the bottom shear stress is assumed constant along a flowline (Orowan, 1949). This gives a simple calculation scheme for an ice sheet profile with an arbitrary bed surface.

Modelling the shapes of glaciers: an introduction

European Journal of Physics, 2019
Abstract We discuss models of the local thickness of glaciers and ice caps. Assuming perfectly plastic ice, as was done in the early days of glaciology, originates models (presented here) that capture some of the features of glaciers, but do not recover real life systems.

Accurate modelling of glacier flow

2010
Recent interest in climatic change and ice .sheet variations points out the need for accurate and numerically stable models of time-dependent ice masses. Little attention has been paid to this topic by the glaciological community, and there is good reason to believe that much of the published literature on numerical modelling of the flow of glaciers ...
