Abstract

The study is focused on spatiotemporal shoreline variability at a beach with a wide surf zone featuring 3-5 bars based on field observations done between 1983-2008 in the south Baltic Sea. The implementation of various analyses from simple geometry, through spectral analysis up to Discrete Wavelet Transform (DWT) allowed for a synergistic description of simultaneous shoreline and dune foot variability in space and time. The results include meso-scale and long-term phenomena with time scales from several months to many years and spatial scales ranking between a few hundred meters up to several kilometers.
