基于变量联合分布的沿江城市雨洪遭遇概率分析
Probability analysis of rainfall and flood encounters in cities along the river based on joint distribution of variable
摘要
Abstract
With the rapid advancement of urbanization,the problem of urban waterlogging has become increasingly prominent.In addition to being related to the precipitation within the urban area,urban waterlogging is also associated with the urban external drainage capacity,which in turn is closely related to the water level of the external drainage river channels.Therefore,it is of great practical significance to study the risk of rainstorm and high water level in external rivers.Taking Nanjing City as an example,the marginal distributions and joint distributions of the annual maximum daily precipitation and the maximum high tide level in a sliding 1-day period at Nanjing Station from 1951 to 2022 were respectively fitted,and the single risks and co-occurrence risks were analyzed.关键词
