周口水文站是沙颍河周口市区主要控制站,自建站以来水位流量关系基本稳定,2010年汛期沙颍河出现了2000年以来的最大洪水过程,测得最大流量2700m3/s,最高水位49.62m,与历年水位流量关系对比水位偏高0.76m,这种情况对防汛抗洪极为不利。文章在调查的基础上对2010年洪水位偏高原因进行了初步分析,希望能对今后的防汛工作起到一定的作用。
The Zhoukou Hydrological Station is the main control station in the urban area of Zhoukou in the Shaying River. Since the establishment of the station, the relationship between the water level and the discharge has basically been stable. In the flood season in 2010, the largest flood occurred since 2000, with a maximum flow rate of 2700m3 / s and a maximum water level of 49.62 m, compared with the previous years, the water level is higher than the water level 0.76m, this situation is extremely unfavorable for flood control and flood fighting. Based on the survey, the article makes a preliminary analysis of the reasons for the high flood level in 2010, hoping to play a certain role in the flood control work in the future.
