Occurrence of channel-reach morphologies with specific ratio of transport capacity to sediment supply (e.g., bedrock channels, cascades, step-pools, pool-riffles) in mountainous landscape is driven by several internal and external time-variable and space-variable factors. Especially, the identification of sediment supply potential is crucial for later stream management in mountains. The contribution deals with theoretical aspects of stream restorations of this part of stream net with emphasis on the flysch Western Carpathians.
