abstract = {Soil salinization in irrigated croplands is a key factor in
soil degradation and directly affects plant growth and soil
hydrological processes such as evaporation and infiltration.
In order to support the development of appropriate
irrigation strategies, it is important to understand the
impact of salt crusts that form during evaporation from
saline soils on water flow. The determination of the
effective hydraulic properties of salt crusts that control
evaporation is still a challenge due to the lack of suitable
measurement techniques. In this study, we propose an
approach using gas flow to determine the permeability of
salt crusts obtained from evaporation of unsaturated saline
solutions of three different salt types and investigate the
impact of the crust permeability on evaporation. For this,
sand columns saturated with initial solutions of sodium
chloride (NaCl), magnesium sulfate (MgSO4), and sodium
sulfate (Na2SO4) at concentrations corresponding to $33\%$
of the solubility limit were prepared and allowed to
evaporate in order to induce crust formation. The results
demonstrated that the intrinsic permeability of the dry salt
crusts was similar for the different types of salts
(≈4×10−12m2), whereas the evaporation of the prepared
columns differed significantly. We conclude that the
intrinsic crust permeability only partly explains the impact
of the crust on evaporation. Other effective crust
properties such as porosity or unsaturated hydraulic
properties may provide additional information on how
evaporation is affected by salt crust formation.},
