摘要
基于MSWEP卫星反演降水数据延长APHRODITE降水数据系列,采用改进的统计法和SCS模型估算湄公河S1水电站坝址PMP/PMF,并与实测流量系列的频率分析结果进行比较验证。求得S1水电站坝址万年一遇校核洪水为91,700 m3/s,PMF估算结果为112,950 m3/s;S1坝址可能最大洪水约为万年一遇校核洪水的1.23倍。这与上游梯级电站的设计成果基本一致,研究结论基本合理。
Based on MSWEP satellite retrieval precipitation data, the extended APHRODITE precipitation data series are used to estimate the PMP/PMF at the S1 Hydropower Plantdam site in the Mekong River based on the improved statistical method and SCS model, and compared with the flood frequency analysis results. It is shown that the 10,000-year check flood of the S1 dam-site is 91,700 m3/s, and the estimated PMF is 112,950 m3/s. The PMF is about 1.232 times of the 10,000-year check flood, which is consistent with upper cascade reservoir designed values and the conclusion is basically reasonable.
