When we established the gravity-tension balance equations assuming that soil pores are interconnected with each other, the capillary migration path of water is not like a single capillary tube, meaning that channel interleaving was bent and most of the gas-liquid interfaces on the same section are connected.
Capillary migration of moisture may occur in any material with a pore structure.
The second stage of drying commences when the evaporated volume is no longer replenished adequately by capillary migration of liquid from the interior to the surface, or when lateral diffusion inside the boundary layer is insufficient to compensate for the loss in surface area.
