Abstract:With the increasing frequency of extreme weather events, to ensure the urban safety, it is particularly important to do a good job in the investigation of flood control safety hazards. On the basis of expounding the current methods, approaches and effectiveness used and achieved in the investigation of flood control safety hazard, the investigation results are analyzed in detail, and the existing shortcomings are summarized, such as a lack of traceability of the causes of potential hazards, the accuracy needs to be improved, the insufficient reliance on informatization and the poor connection with emergency response in the current investigation of flood control safety hazards. It is proposed that in the future, the improvement measures should be adopted, such as precise policy implementation based on classification, optimization of investigation strategies, enhancement of the digitalization level of investigation, and improvement of the investigation work system construction, which further enhances the investigation level of flood control safety hazards, and provides a reference for the other provinces and cities in improving the investigation capabilities of flood control safety hazards.
