This study describes the behavior of bedload transport and bed morphology in the Wloclawek Reservoir, simulated with the PTM model. Through numerical simulations, the interaction between flow dynamics, material transport and deposition was investigated. This analysis was carried out based on two variables: the height of sediment bedforms and the change in the bed level. The results were obtained for medium to high Vistula River discharges: 780, 1143, 1630 and 2990 m³·s^–1.</p> 1 1. Mączka, N.
