The presented research analyses the impact of deflectors on sediment transport processes. The basis for analysis is a hydrodynamic model of downstream part of the Flinta river. The geometry reproduction was performed using spatial data: digital elevation model (DEM) and cross-sections of considered reach. The computations were calculated in HEC-RAS 5.0.1, a common software used to calculate water surface profiles and sediment transport. In the research, two calculation variants were analysed: (1) with initial geometry of channel, and (2) with geometry after introducing deflectors. In order to take into account uncertainty, five scenarios of 10-year flow hydrographs were tested. To calculate the intensity of sediment transport, the Engelund-Hansen formula was used. The results suggest a possible initiation of local scours near the structures.
