• Soil water movement

Based on the effect of infiltration head on soil water movement, the assumption of layered calculation was put forward. The model of soil water movement at different infiltration heads was established, and the finite difference method was used to solve it. A series of soil column infiltration experiments at different infiltration heads were conducted to verify the model. The computational soil water contents derived from the model was in accordance with the experimental results, the maximum relative error was 4.8%. It indicates that the mathematic model of soil water movement at different infiltration heads is correct and solving of the model with the finite difference method is feasible.
