良相坡蓄滞洪区防洪工程设计OA

The Liangxiangpo Flood Storage and Retention Area in Weihui City is a vital component of the comprehensive flood control system for the Zhanghe River and Weihe River within the Haihe River Basin,playing a significant role in alleviating the flood pressures on the Weihe River and enhancing the flood control standards across the basin.Taking the design and approval documents for the flood storage and retention projects of the Huaihe River Basin in Henan Province for reference,this study proposes a dredging plan based on a three-year recurrence flood discharge standard.Upon completion,through integrated operation of the project with rivers and reservoirs,the peak flood volume can be reduced and the excessive floodwater can be stored and released,achieving a balance between flood storage and discharge.This can enhance the overall flood resistance capacity of the river basin.
