Abstract

When a system of 5 check dams to hold back movements of rock debris was built along the forested reaches of the Černy Potok River, the result was accumulation above and erosion below. Analysis of reductions in tree-ring widths and exposure of roots in the area's trees allowed for the dating of riverbed transformation. The riverbed was transformed intensively in the years 1921, 1971, 1978-79, 1984-87 and 1997-99. The check dams become filled with organic and mineral sediment over a period of 50-60 years. There are no simultaneous erosion and accumulation episodes, i.e. synchronicity, in the individual dams as result of the supply of fresh sediment into the river channel from cut-bank sections and the stepwise transport of coarse-grained material over short distances. - (BJ)
