Abstract：The reconstruction of Airport Drainage River Bridge No.1 is part of the Donghuan Line renovation project in Wuqing District,Tianjin.The bridge spans the western branch of the Airport Drainage River,and a flood impact assessment is required as per relevant regulations.This paper determines the flood control standards,calculates the design flow and water level,and performs calculations for backwater and scouring analysis.A comprehensive evaluation is conducted,considering aspects such as planning adaptability,river flood discharge capacity,river regime stability,and impacts on other engineering facilities.Based on the evaluation conclusions,suggestions to mitigate adverse effects are proposed,providing technical support for relevant organizations undertaking the project.
