Abstract
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.

The intensity and frequency of extreme incidents have increased during recent years, and water logging disasters have become the most important disasters related to climate change which have been a sensitive issue faced by cities all over the world (Arnold & James, 1996; Katz & Brown, 1992; Vincenzi, De Leo, & Bellingeri, 2012; Easterling et al, 2009; IPCC, 2012), and it affects the urban planning and construction, as well as the management and regulation of urban ecological environment
Summary
Urban water logging is a phenomenon in which urban heavy rains or continuous rains exceed drainage capacity, resulting in water logging disasters. The intensity and frequency of extreme incidents have increased during recent years, and water logging disasters have become the most important disasters related to climate change which have been a sensitive issue faced by cities all over the world (Arnold & James, 1996; Katz & Brown, 1992; Vincenzi, De Leo, & Bellingeri, 2012; Easterling et al, 2009; IPCC, 2012), and it affects the urban planning and construction, as well as the management and regulation of urban ecological environment. A large number of water logging prevention and drainage projects have been constructed in cities, and non-engineering disaster reduction measures have been taken, the problem of urban water logging has not been effectively solved, and it shows a tendency to increase in local regions. Taking a coastal city—Ningbo as an example, it is a key measure to improve the ability to prevent water logging disasters by analyzing the causes of water logging, the problems in the prevention and management of water logging, and making prevention strategies according to different local conditions
