Abstract
Abstract Several sedimentary records of floodplain sediments in the Werra valley and subcatchments have been analysed in order to investigate the influence of climate change on the sediment transport system. In the sedimentary records of the subcatchments a marked change from minerogenic to organic sediments is visible about 14.6 ka B.P. According to palynological analyses this change occurs in a period with a remarkable rise in arboreal pollen percentages. In addition, a reverse change from organic to clastic sediments takes place shortly after 12.9 ka B.P., coincident with a decrease in arboreal pollen percentages during this period. Assuming that changes in vegetation cover are mainly caused by climate, the variations in the sedimentary records are also attributed to these climatic oscillations. In contrast to the subcatchments, comparable changes in the sedimentary record are not detectable in the floodplain of the Werra River. This points to the conclusion that the influence of Late Glacial climate fluctuations on the sedimentary regime of a river with a relatively large and a more heterogeneous catchment seems less pronounced.
