Climate Change Risk to Coastal Airfield Stormwater Systems
Climate change is resulting in rising sea levels and increased rainfall, posing new challenges to stormwater management, particularly along coastlines. The airfield stormwater systems of Tyndall Air Force Base discharge directly into an interior bay of the Gulf of Mexico through tidal canals and ditches, creating a risk of system inundation from high tidewater conditions from sea-level rise (SLR). This study explores the performance and consequences of an inundated stormwater system from SLR during rainfall events using the EPAs Stormwater Management Model (SWMM). One hundred and fifty-three combinations of SLR and return year storms were applied to a model of an independent stormwater system servicing the Bravo taxiway, and analysis of the results indicate that SLR projectionsassociated with 2065 under high emissions and 2100 under medium emissions will result in widespread flooding, surcharging, and capacity limitation in stormwater inlets and conduits adjacent to airfield pavements and proximate tothe system outfall. The results of this model warrant future study and validation, while indicating that the Department of Defense needs to account for the dual threat of SLR and intensified rainfall in stormwater planning.
