Short Summary

This study develops a high-resolution integrated modeling framework (HiPIMS-PSM-FIM) to simulate urban multi-source flooding with mobile pumping operations, demonstrating its effectiveness in reducing flood impacts and enhancing resilience in coastal cities.

Objective

• To develop and apply a High-Performance Integrated Hydrodynamic Modeling System–Pumping System Model–Flood Impact Assessment Model (HiPIMS-PSM-FIM) framework to evaluate object-level exposure and quantify the benefits of mobile pumping for urban flood protection.

Study Configuration

• Spatial Scale: Urban area of Yuhuan City, Zhejiang Province, China, at 3 meter resolution.
• Temporal Scale: Dynamic simulation of a multi-source flood event.

Methodology and Data

• Models used: High-Performance Integrated Hydrodynamic Modeling System (HiPIMS), Pumping System Model (PSM), Flood Impact Assessment Model (FIM). PSM is two-way coupled with HiPIMS using a Source Coupling Method.
• Data sources: Field surveys (for validation), exposure data.

Main Results

• The HiPIMS-PSM-FIM framework demonstrates strong agreement with field surveys when applied to a multi-source flood in Yuhuan City.
• Vulnerability analysis indicates that Children are more vulnerable than Sedans, which are more vulnerable than Adults, who are more vulnerable than SUVs; educational facilities face the highest risks.
• Mobile pumping can reduce the affected population by 82% and decrease impacts on key facilities and roads.

Contributions

• Development of a novel, high-performance integrated modeling framework (HiPIMS-PSM-FIM) that two-way couples a pumping system model with a hydrodynamic model for high-resolution urban multi-source flood simulation.
• Integration of pump operations into high-resolution simulations, addressing a gap where previous studies used simplified methods.
• Quantification of the benefits of mobile pumping stations at an object-level, demonstrating significant reduction in affected population and impacts on critical infrastructure.
• Provides a robust and practical tool for enhancing urban flood resilience and supporting mitigation strategies.
