Abstract
Heat, liquid water, vapor movement theory, not including Kelvin's relation and equation of state, was proposed and was combined with a solute transfer model to assess the secondary salinization, i. e. the re-accumulation of salt near the soil surface following the elution from an initial salt accumulated layer after precipitation. The proposed model was, therefore, extended to analyze the moisture movement from funicular to pendular moisture state. The computation could reproduce vertical profiles of temperature, volumetric water content, vapor density and salt concentration in a soil column including a salt accumulated layer after watering the soil surface. It was confirmed that the secondary salinization is sensitively affected by the watering rate, watering times and the depth of the initial salt accumulated layer.
