520 _ _ |a Salt precipitation from evaporation is a key factor for soil degradation due to salinization in arid and semi-arid regions. It also plays a key role in porous construction material deterioration due to salt weathering. Evaporation-induced water movement transports dissolved salt ions to the surface of the porous medium where they accumulate. When the solubility limit is reached, salt starts to precipitate and forms crusts on top (efflorescence) or inside (subflorescence) of the porous medium depending on the type of solute in solution. For the development of strategiesto treat salt-affected porous media and to prevent precipitation, it is important to understand the formation and the impact of the salt crusts on water flow during evaporation. Salt crust formation depends on ambient factors such as temperature, relative humidity, and wind speedover the porous medium, and also on solution properties, such as the type of dissolved ions and viscosity. However, it is not known how the hydraulic properties of the porous medium such as porosity, permeability, and water retention affect evaporation and crust formation in detail.In this context, the overall aim of this thesis is to improve understanding of the impact of salt crusts on evaporation with a focus on the porosity, the intrinsic permeability, and the spatial and temporal development of salt crusts.
