Evaporation from a porous medium can induce the precipitation of salt, thus leading to the formation of a porous salt crust. Depending on the topology of the system, the precipitated salt crust can either enhance or hinder evaporation . A better understanding of the water transport properties near aqueous/solid salt interfaces is necessary to predict the formation and impact of precipitated salt crusts, which is vital for arid regions where soil salinisation due to irrigation is a critical problem .
