In this context it is di–cult to use common abso-lute dating techniques because they require datable material which is often not available.Additionally, these methods do not always date the time since the formation of these struc-tures. For these reasons the application of geomorphological dating seems one possibilityto date certain geomorphological features.The aim of this study was to relate present-day shapes of terrace risers to their ages. Thetime span since scarp formation ceased is re ected by the stage of degradation along withthe rounding of the proflle edges due to erosive processes.
