| Abstract: |
| Based on the infiltrating character of FBFI mathematical models are developed to simulate infiltrating of FBFI by the use of the modified Richards’equation．Combined with initial condition boundary condition and relative parameter numerical solution is obtained by Galerkin finite element method．The founded model is steadier and reasonable and well agreed with the data obtained from field irrigation experiment by validating． It establishes the base for futther studying infiltration characteristic and surface flow moving characteristic irrigation technical parameter optimization system management and design etc. |
