Numerical Modeling of Soil Evaporation Process and Its Stages Dividing during a Drying Cycle

Figure 2

The liquid water (red solid line), water vapor (red dashed line) water fluxes, and the total flux (black solid line) at the soil surface. The left vertical dashed lines represent timing point of shift of evaporation process from stages 1 and 2, and periods between the two dashed line indicate the transient stage of evaporation process (same below).
