摘要
Construction of regular arrays of groynes along the Upper Odra channel created a new environment for sediment deposition. The inter-groyne infill is a significant sink for material transported in the Upper Odra channel. Sediment accretion rates were derived using artefacts as the alluvia age indicator. In the last 40 years the average rate of sediments accretion has been 5 cm year(-1) while shortly after channel stabilization the rates ranged from 1.2 to 2.8 cm year(-1). During large floods up to 30 cm per event have been deposited.
