Research on the emergency management pattern and adjustment system for urban waterlogging

Abstract

Urban waterlogging events have become more frequent in big cities, causing a considerable economic loss and casualties. Waterlogging disasters exert increasingly severe influences on cities, which has become a research hotspot under changing environment. In view of that problem of insufficient information in the waterlogging emergency management, it is necessary to build emergency management pattern to adapt to the changing environment of urban waterlogging and design support emergency management pattern implementation of adjustment system. Through the process of "pre-event, in-event and after-event", a set of emergency pattern is designed to face the urban waterlogging event, which ensures that the management personnel could grasp the state of the occurrence of the event at each stage of the event and take countermeasures for the occurrence of the event quickly. The digitalization and visualization of urban waterlogging emergency management can be realized by using customized components, drawing knowledge map and designing adjustment system. According to the urban waterlogging emergency management pattern, the Beijing emergency plan component and the component based on similar historical case analysis are customized, and the functions of the components are realized through the integrated adjustment system. The application shows that emergency management adjustment system of urban waterlogging can realize the quick use of information, offer users customized waterlogging emergency management services, and provide the management with the support of effective emergency management decision. The results can provide conceptual and technical support for urban emergency management. It can also improve the timeliness of urban response and the level of urban flood control.
