“…Furthermore, the evaporation and condensation of water vapor are determined by the pressure head and temperature gradient. The results of water vapor movement simulation in this paper show similar characteristics as previously reported [41] during summer, when the air temperature was higher than the temperature of the groundwater (Figure 10b). However, the zero flux interface is formed in deeper soil in the autumn (Figure 11b).…”

“…The temperature gradient changes due to diurnal temperature variations, resulting in the evaporation and condensation of water vapor in the soil. Zeng, et al [41] found that the movement of water vapor can be described by three stages in shallow soil layers over the course of a day. Furthermore, the evaporation and condensation of water vapor are determined by the pressure head and temperature gradient.…”

“…11). Zeng et al (2008) found that the thermal water vapour and liquid flux were dominant in uppermost soil layer at night, whereas the isothermal liquid water dominated during the day and in the deeper soil layer and this is evident in Fig. 11.…”

“…As can be seen, if B 2s is situated closer to either B 1 or B 2 , the weight of e´B 2s will not represent the second layer. Under the precondition that the annual averaged soil temperature tends to be homogeneous throughout the soil profile [23][24][25], to enable the layer representativeness of B 2s , the difference between B 2´B2s and B 2s´B1 has to be made as small as possible. Meanwhile, to enable the grey and the green area to be equal in size for the second layer in Figure 2a, the ratio should not be smaller than a constant, considering the shape of the f pxq " e x´x x curve.…”
