Dynamic Assessment of Urban Interdependent Infrastructure Failure Risk Under Heavy Rainfall and Flooding

In this paper, we analyze the failure of critical urban electricity and water infrastructure under heavy rainfall and flooding, and analyze the multiple associations that lead to the failure. The multiple associations are classified and defined based on their causes, mechanisms and scope of influence. The coupling mechanism and dynamic evolution process of multiple correlations are analyzed with respect to the spatial and temporal evolution characteristics of heavy rainfall and flooding disasters. A joint probabilistic approach is used to couple the multiple associations and construct a multiple association dynamic evolution network to dynamically assess the failure risk of urban electricity and water critical infrastructure.
