Abstract

In the study of soil salinization, the hydrodynamic dispersion coefficient is an important parameter for solute transport. However, dispersion coefficients for soils require a great deal of time and effort, especially for silts and clays, which can be complicated and prolonged to measure. In this study, the hydrodynamic dispersion coefficients of silt and clay were determined by laboratory experiments and numerical analysis under different saturation states. By comparing with the conventional method, the applicability of proposed method of to quickly obtaining the unsaturated dispersion coefficient was verified. Additionally, by investigating the relationship between the hydrodynamic dispersion coefficient and the soil pore water velocity, the empirical formula of the soil hydrodynamic dispersion coefficient obtained.
