Abstract：In July 2021,the Weihe River Basin experienced its most severe flood since 1963,leading to the activation of eight retarding basins for flood diversion.Most of these basins relied on temporary breach diversion methods,where the width of the breach became difficult to control after excavation.This resulted in unmanageable inundation areas within the retarding basins.To enhance the operational flexibility and controllability of flood diversion in retarding basins,minimize inundation losses,and enable adaptive scheduling during flood events,it was proposed to modify the originally approved spillways of the Baisipo and Changhongqu retarding basins.The modifications involved replacing the standalone spillways with a combined system integrating spillways and floodgates.Following the approval of the design revisions,the Weihe River Construction Management Bureau promptly adjusted the engineering contract terms and finalized supplementary agreements to ensure the smooth implementation of the project.
