AbstractNuisance flooding, which causes public inconveniences such as frequent road closures, overwhelmed storm drains and compromised infrastructure (NOAA, 2017), has noticeably increased at multiple mid-Atlantic coastal locations in recent years. Multiple factors contribute to such flooding events, however mean seal level rise (MSLR) is a primary driver, due to its effect on increasing the exceedance probability of a given storm leading to flooding. Preliminary results show a tendency for a weakly non-Gaussian distribution of the extreme water level probability density function at multiple gage locations, which suggests that dimensionless extreme water level peaks (relative to the mean) will also be related between locations. Implications for both current and future nuisance flood frequency based on these distributions will be discussed.
