Description	Most of the toxic compounds transported by rivers are bound to fine-grained solid particles, which are deposited as contaminated fluvial sediments. Much of this contamination is likely to be redistributed, constituting potential serious environmental hazards. Stratigraphic record of sediment contamination is usually incomplete in the highly dynamic systems such as river channels but it can be more complete in floodplains or oxbow lakes. We studied sediments and stratigraphic architecture of an artificial oxbow lake, a former meander separated by river realignment in 1930s. The lake has been connected to the active channel via a water-gate allowing contaminated fine-grained sediments to enter and settle in the lake. Facies analysis of four cores up to 4m long, supported by ground penetration radar (GPR) profiling allowed us to recognise two major depositional phases.
