港口湾水库入库洪水预报模型研究

Research on Flood Forecasting Model of the Inflow in Gangkouwan Reservoir

基于港口湾、胡乐司流域产、汇流分析,提出了分流域、分单元入库洪水预报模型的整体构架,产流计算应用了蓄满产流模型,汇流计算提出了拟线性河网汇流指数模型:Csj=Cs0+αe-βAj,实现了汇流系数因入流强度自动调整的目标。

Based on the rainfall-runoff analysis of Gangkouwan valley and Hulesi valley a general framework of the reservoir inflow flood forecasting model was presented. The model was composed of classified basins and calculated cells and the natural storage model was used in the calculation of drainage runoff. The simulation linear exponent model Csj=Cs0+αe-βAjwas given to the calculation of runoff. The runoff coefficient will be adjusted according to the intention of inflow automatically by using the model.
