The Gulf Coast has experienced increasingly severe flooding in recent decades, highlighting the need for robust, science-based flood management strategies. Accurate estimates of flood hazards, grounded in historical conditions and considering future projections, are essential for resilience planning. This study employs hydrodynamic modeling to simulate compound flooding in Mobile Bay, Alabama, using the SFINCS model forced by water levels (tide + storm surge), wind stress, rainfall, and river discharge. We analyze scenarios informed by stakeholder priorities, including historical tropical cyclones and synthetic compound events with defined return periods. Future conditions incorporate projected sea-level rise by 2050 and evaluate the effectiveness of various nature-based solutions in reducing flood risk. This presentation gives the “behind the scenes” technical background for generating inundation and hazard maps, forming part of the Cooperative Institute for Research on Hydrology (CIROH) project, “Assessing Nature-Based Solutions to Mitigate Flood Impacts and Enhance Resilience.” A series of talks from this project will address ecological implications, community engagement, and strategies for communicating these tools to end users.
