O článku:
It is important to know the history of occurrence of debris flows, especially with respect to the potential prediction of their origins in future under the changed climate conditions. The temporal occurrence of debris flows in some localities in the Moravskoslezské Beskydy Mts is known. Nevertheless, it is necessary to replenish these data. Debris flows were dated using the dendrogeomorphic methods in the valley of the Bučací potok Brook on the northern slope of the Smrk Mt. Increment cores and cross sections from 35 predominantly broad-leaf trees growing near the debris flow track were used for dating. Eleven debris flow events from the last 70 years were identified. The reconstructed frequency of debris flows makes it obvious that activity has increased since the mid-1980s. Origins of all debris flows are connected with the occurrence of extreme short-term precipitation totals (often more than 200 mm/day). This study should contribute to the knowledge of debris flow chronology in the Moravskoslezské Beskydy Mts.
