Depositional rates and dating techniques of modern deposits in the Brno reservoir (Czech Republic) during the last 70 years

Original language description

Facies analysis, magnetic susceptibility, and analysis of grain size, TOC content and isotopes (137Cs, 210Pb, 226Ra, 228Ra, and 238U concentrations) were used to determine the history of the modern deposits of the Brno reservoir. The sedimentary succession can be subdivided into two main units. The lower unit is interpreted as a fluvial succession deposited before the Svratka River was dammed. The upper unit is interpreted as a product of the reservoir deposition. The concentrations of 238U reflect thehistory of uranium mining in the upper part of the Svratka River catchment. As a consequence, 210Pb radionuclide concentrations cannot be used for establishing a sediment chronology. Concentrations of 137Cs show two marked peaks, the upper of which is attributed to the Chernobyl reactor accident in 1986, and the lower one is attributed to the maximum rate of atomic weapons testing in 1963. From these peaks, mean depositional rates of 3.2 cm y-1 for the time period of 1986 to 2007 and of
