Abstract：Urban waterlogging,characterized by diverse causes and widespread impact,constitutes a fundamental societal issue.This article analyzes the multifaceted causes of urban waterlogging and proposes enhancing the city's ability to respond to such disasters through information technology.The study constructs an urban waterlogging waming and forecasting system based on real-time IoT sensing,data aggregation,mathematical modeling for prediction,big data analysis,and hydraulic digital twins.The system was applied in Ningbo,featuring functionalities such as"space-based"monitoring and early warning,"rainfall"monitoring and early warning,waterlogging forecasting and early warning,cause analysis,and impact assessment.This comprehensive approach allows for precise simulation of urban waterlogging,online risk map generation,and efficient assessment of waterlogging losses.The system significantly supports the prediction and early warning of urban rainstorm and waterlogging disasters,enhancing the city's capability for waterlogging risk management and control.
