南流江洪水预报方案与防洪减灾对策

Flood prediction scheme and flood control countermeasure for Nanliujiang river

分析了南流江流域的洪水成因及特性.通过对南流江常乐水文站洪水利用降雨～径流预报、上游最大流量合成法、瞬时单位线法等3种不同的洪水预报作业方案,进行典型洪水实例预报分析,提出了河库联合调度洪水和建设洪水预警预报系统等防洪减灾对策,科学管理洪水,减少因洪水灾害造成的损失.

An analysis was made on the flood origin and characteristics of Nanliujiang river basin.With three flood prediction schemes including rainfall-runoff prediction,upstream peak discharge synthesis method and instantaneous unit hydrograph,example prediction analysis of typical flood was conducted based on the data from Changle hydrological station on Nanliujiang river.Some countermeasures for flood control are presented including joint flood regulating of reservoir and river,construction of flood forecast system etc.It is put forward that scientific control of flood will be able to reduce the losses caused by flood
