Consolidation in the presence of sorption and consolidation-induced advection

13 For solute transport in a deformable clay liner, the importance of consolidation 14 in the presence of sorption and consolidation-induced advection are well known. 15 Here a one-dimensional coupled consolidation and solute transport model for a 16 partially saturated porous medium, including the new features of finite strain and 17 geometric and material nonlinearity, is proposed. A new boundary condition at the 18 compacted clay liner (CCL) base is also introduced. A comprehensive compar19 ison demonstrates the significance of finite strain, compressibility of pore water 20 (CPW), longitudinal dispersion (LD) and the degree of saturation on the solute 21 transport in an unsaturated porous medium. 22 Consolidation in the presence of sorption and consolidation-induced advection 23 both affect solute transport in a deformable clay liner. Here, a one-dimensional 24 coupled consolidation and solute transport model for a nearly saturated porous 25 medium, including finite strain and geometric and material nonlinearity, was pro26 Preprint submitted to Journal of Hydrology November 20, 2012 posed. A new boundary condition at the compacted clay liner base was also in27 troduced. The model demonstrates the significance of finite strain, pore water 28 compressibility, dispersion and the degree of saturation on solute transport in an 29 unsaturated, consolidating porous medium. 30
