A practical problem of pollutant migration has been studied for dierent concentration dierences and mass diusivities using the ยฎnite element method. The results indicate that the pollutant takes years to travel 10 m into the water-saturated soil when the mass diusivity and concentration dierences ar

In this paper we describe a fast parallel method for solving highly ill-conditioned saddle-point systems arising from mixed finite element simulations of stochastic partial differential equations (PDEs) modelling flow in heterogeneous media. Each realisation of these stochastic PDEs requires the sol
## Abstract We present a new numerical scheme for the approximation of solutions of transient water infiltration problems in heterogeneous soils. The twoโphase (water and air) flow problem is governed by a pressureโvelocity equation coupled to a saturation equation. The numerical scheme combines a
A fully coupled numerical model is presented for the water-table uctuation and land deformation in partially saturated soils due to surface loading. This numerical model is developed based on the poroelastic governing equations for groundwater ow in deforming variably saturated porous media and the
## Abstract This paper presents a fully coupled finite element formulation for partially saturated soil as a triphasic porous material, which has been developed for the simulation of shield tunnelling with heading face support using compressed air. While for many numerical simulations in geotechnic
