In this paper,an area in the northeast region is selected as the study area,and a 1D/2D coupled urban flooding model is established using InfoWorks ICM software.The model simula-tion results show that under design rainfall scenarios with return periods of 1 year,3 years,5 years,10 years,20 years,and 30 years.,more than half of the drainage network in the study area is overloaded.Under the standard of 3 years,the drainage capacity of the study area is only 27.7％.Under the 30 year design storm scenario,severe waterlogging occurs in many places in the study area,with a maximum waterlogging depth of 1.2 m,and the high-risk areas for urban flood-ing were mainly located in the vicinity of Bamiantong street and Ussuri road.In order to improve the efficiency of urban flooding emergency management,this paper proposes an intelligent man-agement program for urban flooding based on the evaluation of flooding risk level,which can pro-vide a reference for the urban emergency management department to prevent flooding manage-ment.
