About article:
A staircase-like longitudinal profile of the Topľa headwater stream channel is analysed and the resultant parameters of step heights, wavelengths, relative steepness and vertical sinuosity are compared with well-established values published in other studies. While the mean step height and wavelength do not show significant differences, the relative steepness factor and vertical sinuosity index are relatively low compared to the theoretical values of a developed and stable step/pool system, performing as the maximum flow dissipator. Recent extreme flood events in the Topľa watershed may be the cause of system disruption. However, a recovery of the system stability was observed in other step-pool channels worldwide indicating that these rhythmic forms reflect a general self-organization phenomenon operating on the earth’s surface.
