Our paper summarizes the results of bedload transport modelling in the Morávka River, Ostravice River and Bečva River basins, conducted with the use the BAGS (Bedload Assessment for Gravel-bed Streams) spreadsheet-based program. The presented results show potential rates of bedload transport linked with identification of erosion and accumulation processes in channels. Selected channel cross-sections include preserved gravel-bed reaches with anabranching development as well as transformed reaches with accelerated deep erosion and occurrence of a single bedrock channel. The modelling shows bed load transport trends in relation with the morphology of the channel. Presented results show a potential rate of bed load transport because sediment inputs and barriers were not included in the model. In fact, these results of potential rates of bed load transport can be use for distinguishing of the reaches with erosion or accumulation trends.
