Foreword Shanghai is located in the southeast coast of our country, north of the Yangtze River, Hangzhou Bay in the south, low lying, long coastline, high tide, frequent heavy rains, while the existing flood control facilities defense ability is low, hit by heavy rain, some parts of the urban area Water is inevitable. In order to minimize the disasters caused by typhoon, heavy rains and orgasms and minimize losses, apart from relying mainly on engineering measures such as continuously improving the design standards and actual defensive capabilities of seawalls and urban flood control walls and continuously improving urban drainage Facilities, and continuously improve urban drainage design standards, non-engineering measures play an extremely important role in flood control work in Shanghai. According to Shanghai in recent decades to prevent
