Abstract:: One-dimensional solute transport model is numerically solved with finite volume method in unsaturated soils.The dynamic procedures of soil water movement and solute transport are simulated.The rationality and validity of simulated results have also been verified by experimented data.Through comparing finite volume method (FVM) with finite difference method (FDM),it shows that FVM can avoid the phenomenon of numerical disperse and numerical shake which frequently happens in FDM.Therefore,for simulating soil water and solute movement,finite volume method is a good and practical numerical method in engineering application.
