棉花滩水库建成后对青溪水库设计洪水影响研究

Effect of Mianhuatan Reservoir on the design flood of Qingxi Reservoir

采用由实测流量推求设计洪水的方法,分别以考虑棉花滩水库影响和不考虑棉花滩水库影响两种途径对青溪水库的设计洪水进行了分析计算.结果表明,棉花滩水库建成投入运行后对青溪水库的设计洪水有一定的影响,且对青溪水库防洪有益;青溪水库可以适当提高其汛限水位.

The design flood of the Qingxi Reservoir was derived from the measured data with and without consideration of the influences of the Mianhuatan Reservoir. The result shows that the operation of the Mianhuatan Reservoir has certain influences on the design flood of the Qingxi Reservoir, and is beneficial to the flood control of the Qingxi Reservoir. Accordingly, the flood control level of the Qingxi Reservoir can be properly raised.
