It is thus indispensable to consider a fully coupled hydro-thermalmodel to well estimate the variations of soil temperature and volumetric water content. In this study, a numerical approach combining afully coupled hydro-thermal model and a soil-atmosphere interactionmodel is adopted to study the coupled hydro-thermal behavior of soilduring evaporation. Four different evaporation tests with recording soilhydro-thermal behavior in an environmental chamber conducted bySong et al. (2013, 2014) and Song (2014) are considered to verify theproposed approach in the specific laboratory conditions. The numericalmodelling is conducted through the FreeFem++ code (Hecht, 2010)with Finite Element Method. Moreover, the variations of soil temperature and volumetric water content in four evaporation tests arefurther discussed, suggesting the significant influences of water andheat flux boundary conditions.
