受副热带高压和切变线以及低涡的共同影响,造成今年7月3日8时至4日8时沙澧河上游的大暴雨和局部特大暴雨,沙颍河干流出现了1982年以来的最大洪水。在防御这次大洪水的过程中,省防办做了精心组织,合理调度,充分发挥了现有水利工程的削减洪峰、蓄滞洪水的功能,根据降雨和河道水情及时修正调度方案,把洪水损失减少到了最小限度,确保了大中型水库、沙澧河堤防、漯河市、周口市、京广铁路和人民生命财产的安全。但是,在这个过程中也暴露出了一些问题值得我们进行更进一步探讨,以使我们今后做得更好。例如,由于6月25日的降雨,使昭平台水库超蓄了大量的洪水而没有及时排泄、腾出库 Affected by the subtropical high and shear line and the low vortex, heavy rains and localized heavy rainfall occurred in the upper reaches of the Shahe River at 8 o’clock on the July 3 this year between 8 am and 8 April. The largest flood in the Shaying River since 1982 . In the course of defending this great flood, the provincial defense office did meticulously and rationally dispatched and gave full play to the functions of cutting down floods and storing floods of existing water conservancy projects, and timely adjusted the scheduling plans according to rainfall and river conditions Flood losses reduced to a minimum, to ensure the safety of large and medium-sized reservoirs, Shahe River embankment, Luohe City, Zhoukou City, Beijing-Guangzhou railway and people’s lives and property. However, during this process, some problems have also been exposed that deserve further discussion so that we can do better in the future. For example, due to the rainfall on June 25, a large amount of floods have been accumulated in the Zhaopingtai Reservoir and there is no timely excretion.
