Research on the Application of Composite Model-based Urban Flood Disaster Monitoring

Research establishes a composite model system based on hydrological models, hydrodynamic models, rainfall models, and evacuation models to accurately assess and predict flood disaster risks in specific regions. The study selects the Nanchang High-tech Industrial Development Zone as the target and conducts in-depth data collection and preprocessing. On this basis, researchers utilize the constructed composite model to conduct a detailed analysis of flood disaster vulnerability at candidate locations within the High-tech Zone. By combining the model experimental results with the actual situations at the candidate locations, specific analyses and comparisons of flood disaster risks at each location are conducted. Based on these analysis results, targeted disaster prevention and mitigation strategies and suggestions are further proposed, aiming to provide a scientific basis for flood disaster management.
