| Abstract: |
| 【Objective】 HEC-HMS is a hydrological model to simulate rainfall-runoff process at basin scale, and the purpose of this paper it to apply it to simulate flooding in Zijingguan watershed. 【Method】 Based on available hydrological, meteorological and land surface data, we divided the watershed into 11 sub-watershed. The HEC-HMS model was built based on runoff generation and flow, and it was validated against14 flood events measured in the watershed. 【Result】 The runoff generation parameters in all sub-watersheds were approximately the same, but the flow parameters varied due to the difference in topography between the sub-watersheds. The errors of the simulated peak discharge was < 20%, with RSE ranging from 0.51 to 0.95. 【Conclusion】 The model can reproduce the measured runoff generation and flow in Zijingguan watershed, and can thus be used to predict flooding in the catchment. |
