A coupled model of heat-moisture flow with Penman-Wilson evaporation boundary condition is used for simulating evaporation processes in three 1D vertical columns with different dry densities. The simulation results show that unsaturated evaporation process has three stages, i.e. constant-rate stage, falling-rate stage and residual stage. The depth of drying front has a great influence on soil actual evaporation. The actual evaporation decreases as the drying front advancing downward. The total evaporation decreased with the increase of soil dry density. The velocity of drying front advancing in the soil of higher dry density is faster than that of lower dry density.
