Abstract :
Based on theory of seepage and solute transport, dynamic coupling model of unsaturation water flow and solute transport is established. The established model is used to model study contaminant transport law in two different penetrability soil under the circumstance of continuous and break pollution source, on the basis of sorption, desorption and biodegradation in soil and water environment. The result reflects contaminant transport law truly, and proves validity of this model. The model provides the theoretical basis for quantitatively predicting space-time distribution of contaminant in landfill soil.
