运用雨洪规律进行洪水预报的探讨

Discussion on flood forecasting by using the law of rainfall and flood

详细阐述应用超渗产流模型衰减曲线计算土壤补充水量及时段净雨量,应用净雨生成洪水的转化规律进行洪水预报。以鲢鱼桥、鹤洲、白沙3个水文站为例,运用实测降水量、洪水流量资料对洪水流量过程进行预测验证,结果表明操作方法简单易行,计算结果精度达标。

The supplementary soil water volume and net rainfall in the period are calculated by using part of the attenuation curve of infiltration excess runoff model.Flood forecasting is carried out by using the transformation law of rainfall and flood.Taking the three hydrological stations of Lianyuqiao,Hezhou and Baisha as examples,the forecasting verification of flood flow process is done with measured rainfall and flood flow data.The results show that the operation method is simple and easy,and the accuracy of calculation results is up to standard.
