不同计算方法对HEC-HMS小流域洪水预报结果的影响研究

Study on the influence of different calculation methods on the flood forecast results of HEC-HMS small watershed

有效的山洪灾害预警对减轻山洪灾害的影响和损失具有重要作用。本文以大洋河流域为例,对不同计算方法对HEC-HMS水文模型模拟精度的影响进行研究,结果显示不同的计算方法对模拟结果和精度存在一定的影响,应该结合流域的具体特征选择合适的计算方法以提高模型的模拟精度。

Effective early warning of mountain flood disaster plays an important role in reducing the impact and loss of mountain flood disaster.Taking Dayang River Basin as an example,this paper studies the influence of different calculation methods on the simulation accuracy of HEC-HMS hydrological model.The results show that different calculation methods have certain influence on the simulation results and accuracy.The appropriate calculation methods should be selected based on the specific characteristics of the basin to improve the simulation accuracy of the model.
