The basic research problem of this study involves presenting morpho-dynamic functions of the Wolin cliffed coast along sandy and till sections. Documentary evidence provided by a ten-year cycle of observations (1977-1986) has been utilized. Analysis of the present morphological development of the cliffed coast in Wolin Island has been based on repeated morphological mapping of cliffs and on the compiled morphological and morphodynamic maps. The present approach is a new methodological proposal for the study of the coastal zone.The action of the storm surge is the main process that operates in the coastal zone. Simultaneously, the cliff becomes shaped under the influence of gravity force, water, wind, snow and frost. The cliff's retreat continuously.The extent of the morphodynamic zones recognized, including those of degradation, transport, transport-degradation and accumulation-degradation as well as zone of dynamic equilibrum, varies throughout a year or over a multi-year period and it is dependent on seasonal variations of weather. The denudative system of the cliffed coast in Wolin Island is characterized throughout the year by four morpho-genetic seasons, i.e. autumn-winter, early spring, summer and summer-autumn. The development of the cliffed coast tends to follow the trend of abrasion equilibrium profile.
