Abstract
Sediment supply into gravel-bed stream in the Moravskoslezské Beskydy Mts. constitutes an interesting question. This paper brings new possibility of temporal reconstruction of material movement from gullies and bank scours, using methods of dendrogeomorphology. Growth disturbances on trees and their roots due to material movement were used for dating. Nine years of slope material movement within the last 50 years were identified. Extreme one-day and one-week precipitation totals seem to be important triggering factors of slope material movement.

Keywords:
dendrogeomorphology; sediments; flood; extreme precipitation; the Moravskoslezské Beskydy Mts.
