Coarse sediment transport in Beskydian torrents: Evaluation of critical conditions for bedload motion
Original language description
The contribution summarizes the results of the bedload transport research in headwater streams of Moravskoslezské Beskydy Mts. We applied two methods: flood competence method and marked particle displacement method. The first method included measurementof diameters of the largest transported boulders (200-400 mm) during 5/2010 flood (Q 25 ) in uppermost part of Lubina river and Malá Ráztoka torrent. Transport of marked particles (18-152 mm) was conducted in Malá Ráztoka torrent in the period between 11/2010 and 7/2011 during which several discharges up to bankfull discharge occurred. The latter method was also used in two selected gullies of Malá Ráztoka basin to evaluate the intensity of coarse sediment transport in such initial channels. The relationship between grain diameter and critical conditions (shear stress, unit stream power and unit discharge) were evaluated and compared to than those coming from Alpine and Andine environments.
