An Integrated Modeling Approach to Stormwater Management

An integrated XP-SWMM and TUFLOW modeling framework was used to simulate flood propagation and evaluate the effectiveness of flood mitigation scenarios for the James Madison University (JMU) campus which had experienced frequent flooding historically. A flood mitigation scenario was developed as a combination of new relief pipe system to divert runoff from the off-campus drainage areas and an enhanced drainage system near the campus' outlet point. The developed flood mitigation scenario was simulated to evaluate its effectiveness. The simulated maximum flood depths for this scenario showed significantly decreased flood propagation and accumulation. The 2D visual interface for flood propagation comparison was very effective in terms of communicating the flooding consequences at critical flooding locations to the campus stakeholders.
