Modelling the retreat of Grosser Aletschgletscher, Switzerland, in a changing climate

Martin Funk, Heinz Blatter, Guillaume Jouvet

For more than a century Alpine glaciers have been retreating dramatically, and they are expected to shrink even more quickly over the coming decades. This study addresses the future evolution of Grosser Aletschgletscher, Switzerland, the largest glacier in ...

Existence and stability of steady-state solutions of the shallow-ice-sheet equation by an energy-minimization approach

Jacques Rappaz, Heinz Blatter, Guillaume Jouvet

The existence of solutions of the non-sliding shallow-ice-sheet equation on a flat horizontal bed with a mass balance linearly depending on altitude is proven for fixed margins. Free-margin solutions for the same mass balance do not exist. Fixed-margin sol ...

Modélisation, analyse mathématique et simulation numérique de la dynamique des glaciers

Guillaume Jouvet

We address the free boundary problem that consists in finding the shape of a three dimensional glacier over a given period and under given climatic conditions. Glacier surface moves by sliding, internal shear and external exchange of mass. Ice is modelled ...

Numerical simulation of Rhonegletscher from 1874 to 2100

Marco Picasso, Jacques Rappaz, Heinz Blatter, Guillaume Jouvet

Due to climatic change, many Alpine glaciers have significantly retreated during the last century. In this study we perform the numerical simulation of the temporal and spatial change of Rhonegletscher, Swiss Alps, from 1874 to 2007, and from 2007 to 2100. ...

A new algorithm to simulate the dynamics of a glacier: theory and applications

Marco Picasso, Jacques Rappaz, Heinz Blatter, Guillaume Jouvet

We propose a novel Eulerian algorithm to compute the changes of a glacier geometry for given mass balances. The surface of a glacier is obtained by solving a transport equation for the volume of fluid (VOF). The surface mass balance is taken into account b ...
