An online participatory system for SWMM-based flood modeling and simulation

Area of Science:

• Environmental Science
• Urban Planning
• Water Resource Management

Background:

• Urban flooding risk is escalating due to urbanization and climate change.
• The Storm Water Management Model (SWMM) is crucial for urban rain-runoff simulations but requires complex, collaborative processing.
• Existing resource-sharing platforms lack a dedicated participatory environment for distributed cooperation in SWMM-based flood modeling.

Purpose of the Study:

• To design and implement an online participatory system for effective collaboration in SWMM-based flood modeling and simulation.
• To address the challenges of distributed cooperation among multifield participants in urban flood modeling.
• To provide a framework and tools that facilitate collaborative flood modeling processes.

Main Methods:

• Development of an online participatory system tailored for SWMM-based flood modeling.
• Integration of a guiding framework with multiple participatory activities.
• Inclusion of online auxiliary tools to support collaborative modeling tasks.
• Case study application in the main urban area of Lishui City.

Main Results:

• The developed online system effectively coordinates collaborative flood modeling and simulation.
• The system successfully demonstrated the collaborative process of SWMM-based flood modeling in a real-world urban area.
• Participants could overcome difficulties associated with distributed cooperation in flood modeling.

Conclusions:

• The online participatory system enhances collaboration for urban flood modeling.
• This approach facilitates the research and application of SWMM for flood risk assessment.
• The system provides a viable solution for cooperative flood modeling in urban environments.
