The Rain-Induced Urban Waterlogging Risk and Its Evaluation: A Case Study in the Central City of Shanghai

Waterlogging induced by rain in urban areas has a potential risk impact on property and safety. This paper focuses the of waterlogging evaluates central city Shanghai. A simplified depth model is developed different with drainage capacity rainfall consumption simplifying effect complex terrain characteristics hydrological situation. Based its classification collection, Rain-induced Urban Risk Model (RUWRM) further established to evaluate city. The results show that closely linked drainage, linear relationship between them. More leads higher risk, especially imperfect facilities. can rapidly gives rank caused clear collection. prediction indicate it confident get well truly advance more accurate prediction. general study contribution allows public, policy makers relevant departments operation assess appropriate management reduce traffic intensity personal safety or strategy lead less risk.
