Thermal Flow In Glaciers: Application To The
Lys Glacier (Italian Western Alps)

Abstract
In the present work the thermal flow in a section of Lys Glacier, in Italian Western
Alps, is investigated. This work represents the application of the model presented
in De Biase and Deponti [1]. The velocity field is calculated assuming ice to be a
perfectly plastic material.With this input data, the energy conservation equation is
solved by the Finite Difference Method. In order to accurately model the complex
geometry of the glacier section a regular but non–uniform grid has been used.
General Finite Difference Formulae of second order accuracy have been used. The
model has been applied to a section of Lys Glacier taking into account all the
particular atmospheric conditions of the site and making two different hypotheses
for the geothermal flux value at the base.
