Sedimentation of the Vistula overbank deposits at Tyniec

Summary/Abstract: The study area is located in the gorge section of the Upper Vistula river valley between Tyniec and Piekary near Kraków, where natural and industrial overbank alluvia with a different radionuclide activity, heavy metals content and grain size composition occur. Overbank deposits cover three levels of the floodplain where three cores of deposits were collected. Alluvia of the lowest level along the channel are more heterogeneous and coarser than those on the middle and the highest level. Most of the overbank deposits were accumulated in the lower regime of water flow. On the basis of luminescence dating it was determined that the accumulation of overbank deposits on the first level started 200 years ago and on the highest level – 3,000 years ago.
