There are several models of soil water that consider the soil medium as an active site for chemical, physical, and biological processes with a bimodal porous medium, micro- and macropore systems. Few of these models consider the soil medium as a structured medium with aggregates. However, none considered the swelling-shrinkage properties of these aggregates and the resulting hydrostructural properties of the soil medium, which significantly contribute to the formulation of transfer functions and their parameterization. Thus, soil dynamics literature describes soil properties independently from the aggregated organization of soils and their structural dynamic with water.
