Bankfull widths of steep headwater channels were examined in the Western Carpathian flysch midmountains. The criteria of the top of banks, scoured lines and presence of bank vegetation were helpful in the bankfull width determination. A direct downstream relationship between the parameters of the bankfull width and the watershed area and a negative downstream relationship between the parameters of the bankfull width and the channel gradient were observed in all examined channels similarly to lower gradient rivers. However, streams based in more resistant sandstone flysch and/or influenced by small debris-flows indicated much less dependence between these parameters. Significant differences in bankfull widths were found when channels of the same watershed areas, but located on leeward and windward hillslopes were compared.

W pracy badano przepływy brzegowe na stromych terenach górnych biegów strumieni na obszarze fliszu w środkowej części Karpat Zachodnich. W określeniu przepływów brzegowych przydatne były kryteria dotyczące wierzchnich fragmentów brzegowych, linii przebiegu erozji oraz obecność wegetacji brzegowej. Bezpośredni stosunek pomiędzy parametrami przepływów brzegowych w dół rzeki oraz obszaru zlewni, a także ujemny stosunek między parametrami przepływów brzegowych a nachyleniem koryta zaobserwowano we wszystkich badanych ciekach, podobnie jak w rzekach o niższym stopniu nachylenia. Jednak strumienie usytuowane na terenach zbudowanych z bardziej wytrzymałego piaskowca fliszowego oraz/lub będące pod wpływem cieków z małym rumowiskiem wykazywały mniejszą zależność między tymi parametrami. Istotne różnice w przepływach brzegowych znaleziono porównując koryta z tej samej zlewni, lecz występujących na zboczach leżących po stronie zawietrznej oraz nawietrznej.
