Description :
The AA. describe the results of geomorphological, sedimentological and 14C analyses of Late Holocene fluvial sequences in the Moldova River Valley, originating from the Carpathians mountains and known for the extent of its large floodplain and sediment thickness. Between the Molid and Timişeşti localities, large fossil trunks of trees are exposed in the riverbanks. Six wood samples were selected for radiocarbon absolute dating. The thickness of the alluvial sediments above the sampled fossil trunks varied between 2 and 3 m. Additionally, in the same investigated areas, successive floodplain cross-sections were constructed. For each cross section, all data were used to calculate the local values of bed loads, and these values were compared to the absolute ages of the fossil trunks. The sedimentation rates are discussed in the context of Late Holocene regional and local palaeoclimatic reconstructions as well as that of human interventions.
