Summary/Abstract: A study was conducted to investigate the change in physical and geochemical composition of alluvial sediments in three selected aits along Suceava River, upstream and downstream of the Suceava urban area. Water chemical analyses were also carried out. Pit profiles were dug for each ait to assess the variability of sediment composition with depth. We used grain size distribution, organic matter and carbonate content, elemental geochemistry and magnetic properties to highlight vertical and horizontal variability of the selected parameters. Results show spatially distinct sources for the alluvial material deposited as aits, i.e., input of finer sediments in the upstream part (main river) and coarser material deposited in the downstream part (tributaries). Sediments and water downstream of Cetății Creek are characterized by high organic content, sulphur and heavy metal concentrations, resulting primarily from the discharge of the polluted waters of this tributary into Suceava River.
