Abstract (in english)
   Three vertical sections were sampled. Mineral magnetic parameters such as mass specific susceptibility (÷), ARM, SIRM and their ratios (ARM/SIRM, S-ratio) all show similar variations from section to section. The gradual increase of ÷ and other magnetic parameters in the uppermost 200 cm of each section is the consequence of more intense erosion caused by agriculture activities, which was triggered by medieval colonization in the central Europe and dramatically accelerated during the last 60 years of very intensified land use, when the topmost 50 cm of the floodplain sequences were deposited as verified by the sediment age estimation based on Pb isotopic content and persistent organic substances (DDT, PCB) determined in the sediments.
