ABSTRACT
As pointed out by various author (e.g., Romero et al., 2000) two main mechanisms generally govern the storage of water inside a soil: the first mechanism is mainly related to free water flow inside the macropores between aggregates/grain; the second one is related to water adsorption at the intra-aggregate level. While the second mechanism is virtually independent of the void ratio, the first one is coupled with the mechanical response of the soil (e.g., Vaunat et al., 2000; Casini 2012; Casini et al., 2012b).
