| Abstract: |
| EPIC (Erosion-Productivity Impact Calculator) is a famous dynamic model that can be used to assess the effect of management strategies on field soil and water resources. The mathematical equations to simulate precipitation, runoff, percolation, evapotranspiration, crop water uptake and water stress in the EPIC model are briefly introduced in this paper. It may provide refernces to the management and quantitative research of field soil and water resources. |
