Evaporation front and its motion [PDF]

open access: yesHydrology and Earth System Sciences, 2022
The evaporation demands upon a rock or soil surface can exceed the ability of the profile to bring a sufficient amount of liquid water. A dry surface layer arises in the porous medium that enables just water vapor flow to the surface.
