摘要
高明河水文站稀少,缺少流量实测资料,但有较长的降雨观测资料。从两个方面建立预报方案,一是针对其洪水特点,以水位涨幅与相应的造峰雨量为参数建立一元回归方程,并建立雨量水位速查表。另一方面,建立新安江模型,对其控制站尼教站的流量过程进行预报,由洪峰流量反推洪峰水位,调整参数后的模型预报精度较好。结合两种方案分析,以期为中小河流山洪预警提供依据。
The hydrological stations of Gaoming River are of scarcity,which lacks observation discharge data,but has enough rainfall data.Therefore,the forecasting scheme was established from two aspects.First,based on the characteristics of the flood,a simple correlation calculation was conducted with the data of rainfall and water level.On the other hand,the Xin anjiang model was established,and the flow process of the Nijiao station was forecasted,from which the flood peak water level was derived,results show that the forecasting model has good effect.The two schemes were combined to provide a basis for the early warning of the small and medium basins.
