Abstract

A short review of rhythmic shoreline features is discussed and shoreline planform advance and recession rates for a coastal segment of Florida are investigated. Time series analysis techniques that include parametric spectra, autocorrelation, and cross correlation are utilized to identify low frequency rhythmic patterns in the shoreline. Non-stationarity and phase shifting of rhythmic patterns is identified via comparison of the shoreline changes for different time intervals. Probability density functions of the shoreline change rates are also investigated and found to be in reasonable accord with Gaussian filtered noise.
