Abstract：In view of the fact that flood control in the past mostly focused on the analysis of the impact of urbanization on runoff characteristics,flood simulation and upper-level planning of flood control system,this study selected representative old coastal mountainous areas to analyze the causes of floods,such as mountain floods entering the city,poor internal drainage,and sea tide backflow,and constructed a high-standard,refined and systematic flood control system integrating various measures such as'improving the system,high water and high drainage,low water and low drainage,self-drainage,supplemented by pump drainage,water storage and utilization,and tide blocking and peak shifting'.At the same time,in view of the many misunderstandings and problems in the previous planning and design,such as the scale of mountain flood parallel storage,the scale of mountain flood interception ditch,the scale of municipal rainwater pipe network after mountain and water entering the city,the check of pavement drainage capacity and the flood control calculation of joint operation of sluice and pump in coastal area,the demonstration methods are systematically sorted out and the adaptability analysis is carried out in order to provide experience for the prevention and control of flood disasters in similar areas.
