摘要：The paper presents results from a study of the functioning of slopes in conditions where the dynamic equilibriumhas been upset and sliding has been followed by slope relaxation. The research was an attempt to analyze large-scale changesin slope morphology in the Łososina River basin in the Beskid Wyspowy mountain range caused by an extreme rainfall eventin 1997. The enormous scale of the sliding process that occurred on the slopes of the Łososina basin provided an opportunityto study the role of mass movements in landform development in mountains of medium height. The paper attempts to summarizethe rate and course of slope relaxation processes using geomorphological mapping done from 1997 to 2000. Thestudy tested the hypothesis that following the occurrence of an extreme event, slope relaxation processes will slow downmass movement processes to the point where they stop acting on the slope, and ultimately a new set of slope developmentprocesses will emerge.
