Cliff top recession rate and cliff hazards for the sea coast
of Wolin Island (Southern Baltic)
Abstract. The article presents results of studies on the
rate of erosion of the Wolin Island cliff-coast (NW Poland) during the last
three decades. Trends of geomorphological changes were defined based on
multiannual observations (1984–2014). Changes were controlled by secular and
extreme processes. Research has shown that the intensity of the processes
shaping the Wolin Island cliff-coast were characterized by a clear seasonal
variability. Analysis of hydro-meteorological conditions allowed the authors to
derive the threshold values of the most important factors initiating cliffs
hazard. The destruction of the cliff, differing in range, occurs in the
above-threshold conditions. Multiannual research and direct observations of the
functioning of the cliff-coast conducted herein provided the basis for proposing
the safety shield and information system about the cliff hazard.
