Soil water migration properties and hydraulic parameters were determined under different sodium concentrations by one-dimensional horizontal soil column in red soil. Results showed that Kostiakov model could well fit the relationship of cumulative infiltration with time, and cumulative infiltration was negatively correlated with salt concentration. There was a good power function between wetting front depth and time. The wetting front velocity decreased with the increase of salt concentration. Water content in soil column and soil diffusivity tended to decrease. The inflection point of water i...
