Nuisance flooding duration across the United States
This research evaluates regional differences in the duration of nuisance flood events across the United States. The analysis is built upon a recently derived suite of nationally consistent thresholds for minor, moderate, and major coastal flooding. Within this framework, the duration of minor, moderate, and major events are specified from tide gauge data. The processes driving long and short duration events are defined by assessing the relative contribution of tides, mean sea level, and non-tidal residuals to each event. The duration and drivers of minor flooding at each coastal location are then compared to those experienced by moderate and major coastal flooding events. Understanding the relationship between the frequency and duration of low level flooding will help to distinguish differences in potential impacts, now and into the future.
