| 摘要: |
| 国内外学者利用HEC-HMS水文模型模拟流域降雨径流过程，发现该模型有良好的适用性。【目的】提高紫荆关流域洪水模拟精度。【方法】采用紫荆关流域水文气象及下垫面资料，将流域划分为11个子流域，通过选择产流和汇流计算方法，构建了该流域分布式HEC-HMS水文模型，并从历史实测暴雨洪水事件中选择14场洪水对构建的HEC-HMS水文模型进行了参数率定和模型验证。【结果】率定的各子流域产流参数基本相同，由于各子流域面积不同导致汇流参数也不同。模拟的洪峰流量和洪量相对误差均在20%以内，纳什效率系数为0.51~0.95，模拟与实测的洪水过程线吻合较好，模型模拟精度较高。【结论】构建的水文模型能反映紫荆关流域实际的产汇流过程，可用于该流域洪水过程模拟和洪水预报。 |

| 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. |
