Abstract

Basing on the data of Airborne Laser Scanning (LiDAR) the reinterpretation of relief and morphometry of headwater areas in Babia Góra homoclinal flysch mountain ridge (1725 m a.s.l.) modelled by landslides was made. The newest information source made it possible to determine the distribution of gentle relief landforms indicating the former and/or present directions of transport of colluvia. Four ways of changes in relief of headwater areas followed by changes in their morphometry were analysed. Deposition of huge volume of colluvial material in the bottoms of headwater areas increases the hazard of valley landslide movement. The development of landslides on the slopes of headwater areas is connected with headward erosion in the areas and includes – unlike other areas in the flysch Carpathians – wide range of Babia Góra ridge slope hight. This insures an extremely large load of colluvial deposits which re-model the relief of slopes and bottoms of headwater areas. The data from LiDAR made it possible to distinguish such elements of relief of headwater areas which so far have been neglected in the Polish geomorphological literature.
