Computer modelling in environmental geomechanics

This paper presents a general framework for the computational analysis of environmental geomechanics problems. It is based on heat and multiphase flow in deforming porous media where pollutant transport mechanisms can be added. The governing equations are derived and then discretised by means of the finite element method in space and finite differences in time. Appropriate solution methods are addressed. Examples given involve heat and mass transfer together with pollutant transport in deforming geomaterials and surface subsidence problems.
