As a common concern of the public and a major problem for urban construction and management, urban water logging disasters, especially in coastal cities, which are caused by extreme weather such as typhoons and continuous heavy rains, not only affect the public security of the city, the production and living order of the residents, but also lead to a lot of economic losses. Along with the continuous occurrence of urban water logging disasters, the problems of not paying attention to the drainage project and weak awareness of flood prevention in the process of urban construction have become increasingly conspicuous. Taking Ningbo City as an example, the thesis analyzes the causes of urban water logging disasters from different perspectives, and proposes specific measures to improve the prevention and management ability of urban water logging disasters in Ningbo, so as to offer helpful reference for solving similar problems to solve urban water logging disasters.
