Bedload transport and flow resistance in steep channels - introduction to the issues in the context of mountain basins of the Central European region

Popis výsledku v původním jazyce

Although sediment transport in the uppermost parts of mountain basins may be supply- limited, bedload transport in small torrents represents a potential hazard during extraordinary floods. The authors attempt to review recent worldwide research of bedload and hydraulics the results of which could potentially be applied in local steep channels. Approaches to the calculation of flow resistance (Manning relationship, logarithmic and power-law relationships) and critical conditions of the incipient motion of a bed particle (critical shear stress, stream power, flow velocity and discharge) are closely discussed in order to describe hydraulic and bedload transport conditions in steep headwater streams. In the second part of the paper the authors present twopilot studies from the Western Carpathians and test potential applicability of specific formulas in this region.
