Description :
Sediment profiles from the floodplain of Morava River in the Czech Republic have been collected from exposed river banks and cores and investigated using a set of geochemical proxies validated by granulometry and conventional geochemical analysis. The work was conducted to evaluate the increase in sedimentation rate during Medieval and modern time periods. Correlation of sediments along the current channel belt allows identification of 2 most important synchronous changes in the channel structure over the past 1300 years : in the 13th century and at the end of the 16th century. These changes could be related to central European climatic extremes rather than to land cover/land use practises. Surprisingly, the extrapolated aggradation rate is very small although Morava River watershed has been intensively used for agriculture and its land cover has changed in a manner similar to west and central European rivers.
