| Abstract: |
| HYDRUS-1D model was used to simulate soil moisture profiles under artificial rainfall and good results were obtained.Then it was also used to simulate infiltration under different surface ponding.The simulation results showed that the infiltration rate differs from each other with different surface ponding.When the depth of surface ponding reduces 0.5 cm, soil moisture reduces 1.2%～2.8% at the same observing location.This phenomenon becomes more apparent when the head of water on the surface increases. |
