Spectral analysis of water-level time series provides invaluable insight into the periodic behavior of hydrological processes. This study analyzes wetland hydroperiod, which is commonly defined as the period of inundation and is thought to be mostly annual, using spectral analysis of observed water-level time series. The results show the water level fluctuation observed in West-Central Florida wetlands follow a predominant semi-annual (180 day) cycle, with water levels fluctuating both above and below land surface.
