| Abstract: | The redistribution of soil water in a Huangmian soil column is simulated with two mathemetical models, one model negecting hysteresi s, other taking hysteresis into account. The results show that agreement in more excellent between the measured and computed results in hysteresis model that in negecting hystersis one when evaporation is carried out to the second period. |
