ABSTRACT
The paper analyzes several classical formulas for calculating the beginning of bedload transport, taking into account recent survey of Polish scientists conducted in the field: Egiazaroff formula [Michalik 1990], Wang formula [Michalik 1990], Bartnik formula [1992] and Diplas modified by Michalik formula [1990, 1999]. The analysis is intended to help in the bedload transport incipient motion calculation and interpretation of the results of the bedload transport in mountain streams. An example of calculation of parameters for entraintment of sediment in selected catchment of a mountain stream, in two areas, is included.
