In this thesis, we mapped the morphology of channel beds on two different geological substrates. The first geological substrate consisted of dolomitised limestone, which is the bedrock of the Belica watercourse, and the second of sintered claystones and sandstones, which is the bedrock of the Potuharica watercourse. We analysed the influence of channel slope and width on the morphological forms plane bed, pool-riffle, step-pool and cascades. In addition, we analysed the types of debris, the amount of debris, and the size classes and roundness of the pebbles occurring in each. We found that the channel slope influences the spatial distribution of morphological forms. Cascades and step-pool morphologies were repeatedly observed on higher slopes, while plane bed and pool-riffle morphologies were observed on lower slopes. Our results show a correlation between channel width and the spatial distribution of morphological forms. Cascades were repeatedly recorded in the narrower parts of the channels, while plane bed, pool-riffle and step-pool morphologies were repeatedly recorded in the wider parts of the channels. A good understanding of the morphology of the riverbed is important for the proper management of torrent channels. Our results show statistically significant differences between stage height and channel slope. These results can be applied to the construction of cross-sectional structures, on different geological substrates, where we want to build step heights that already occur naturally in the watercourse.
