| Abstract: | On the basis of soil-water dynamics, soil-water movement rules in upland field with rainfall are researched, and a one-dimensional vertical unsaturated soil-water movement mathematic model is established. Finite difference method is used in solving the mathematic model. The results of model verification show that the results of numerical simulation of the model agree very well with the data observed. Therefore, the model established is feasible. |
