百色水库汛期划分及分期设计洪水的计算

Flood Season Division and Stage Design Flood Calculation for Baise Reservoir

通过详细分析右江流域汛期洪水发生成因及发生时间的规律,结合百色水库优化调度的要求,对百色水库汛期进行划分。根据流域的防汛情况和水库蓄水要求,结合后汛期洪水逐渐过渡的特征,从后汛期蓄水时间提前的可能考虑.提出按旬划分的分期方法.分别计算各分期的设计洪水。

The flood season of Baise Reservoir was divided by analyzing the causes and law of occurance time of floods in Youjiang Basin and demand of optimal dispatching of Baise Reservoir.According to the flood control standard of the basin,the demand of impoundment of the reservoir,and the characteristics of gradual transition of floods in post flood season,a method of dividing the flood season by ten-day was put forward considering the possibility of impoundment being ahead of schedule in post flood season,on the basis of which design flood can be calculated respectively of each ten-day.
