Wissmeier and Barry (2009) proposed the selective radius shift model to relate the changes in hydraulic properties to changes in mineral volume. A pore size distribution model is used to calculate the water-filled part of the pore space and the local pore volume. The linear scaling factor model cannot be used to describe the spatial-temporal evolution of hydraulic properties predicted by their model as it also contains a nonlinear part.


However, for saturated conditions (or assuming that dissolution and precipitation take place in the entire pore-space, Wissmeier and Barry (2010)), the linear scaling model can be applied and, combined with the van Genuchten/Mualem model, gives following equations (Wissmeier and Barry (2010)):
