The research of slope deformations affecting the valley floors brings a more complex view of the phases of the Quaternary relief development in the Flysch Carpathians. Backwater deposits of the landslide-dammed lakes represent stratigraphically and palaeoenvironmentally important sedimentary complexes, which serve as indicators of the dynamics of relief development and palaeoenvironmental changes in this mid-mountain region. Variability of the sediment types in the stratigraphic profiles shows repeated changes in the depositional conditions connected with the environmental (mainly climatic) changes during the Holocene. The radiocarbon dating of the base levels of the sediments deposited in the landslide-dammed lakes ascertains the time of the formation of given landslide. Sufficiently high amount of data shall allow us to reconstruct the local palaeoenvironmental conditions and make correlations with palaeoclimatic reconstructions in other central European ranges.
