| Abstract: | This paper presents a numerical model for solving problems of water and nonconservative contaminant transportation and transformation in variably saturated soils. In this model the finite-difference approximation is used to the water and concentration equations.The numerical modeling of water and contaminant mixing is used to simulate water and nonconservative contaminant movements in unsaturated soils. Results from numerical simulation are compared with the test data. The predicted results are in good agreement with the experimental data. |
