Analysis of bottom position changes in a lowland river on the basis of sediment transport

The paper present an analysis of changes in the Odra River bed position, which is based upon the evaluations of intensity of the sediment transport rate, which is spe-cified by the modified Ackers-White's method. The case of flow between groins and the change of hydraulic conditions has been presented for the newly designed longit-udinal dam. The analyses were carried out for different flow intensities, comparing the results achieved with the measurement in the Hohensaaten-Bielinek section.
