Research on the Application of Unsaturated Soil Water Migration SWCC Models

摘要：

The soil water characteristic curve is very important for controlling movement of the unsaturated soil water. Based on the former models, this paper is simulated with the numerical simulation on Gardner-Simmons and Brooks-Corey and Van-Genuchten. The numerical results show that the VG model has a perfect flexibility in the soil water. At the same time, saturated water content and saturated infiltrate coefficient and residual water content are analyzed and discussed by the sensitivity analysis. The analysis results show that saturated infiltrate coefficient in those parameters is the most intensive than other parameters. Research on the parameters of water movement law can offer theory foundation for the measurement of the basic parameters in the laboratory and on the site.
