The research activities of the modelisation and tomography group are focused on the physics of disordered geological systems. The modelisation in this field requires an original approach combining numerical and experimental studies.

The main objectives of our research are:

• the formulation and the physical investigation of the dynamics of geological systems with respect to the spatial and temporal scales involved;
• the prolongation by numerical simulation of the experimental approach toward the characteristic scales and the dynamical regimes of the geological systems;
• the identification of the pertinent physical observations in order to design new acquisition programs.

The physics of a number of geological systems has still to be formulated. A major difficulty is the analysis and the integration at the geological scales of the physical information obtained at small scales. This work implies close collaborations with other fields like physics, mechanics and numerical analysis.
