Salt Accumulation due to Evaporation from Soil Surface

Abstract

This paper deals with the salt accumulatiom in a sand column due to the evaporation from a soil surface. A solute balance approach was used to estimate the condensation process of salt component, contained in groundwater. Temperature, volumetric water content, solute concentration proflies and evaporation rate were measured, and the temperature gradient was induced by the radiation. It was found that as the radiation gets stronger, the condensation near the soil surface becomes clear and soon. The computation could provide the time changes of temperature, moisture content, solute concentration profiles and evaporation rate, and could model the salt accumulation.
