The study area is located in the tectonized area - the Dukla Nappe thrust zone. Rocks in this region are highly fractured and disintegrated, which predisposes it to the development of landslides. The movement occurs as a combination of slide (mainly rotational) and flow (mainly debris flow). Landslide initiation takes place in the upper part of the slope, in the spring area, as a slide. Flow is mobilized within the landslide body as a result of high precipitation and intensive water infiltration. Flow-like landslides often “use” existing channel of the catchment to transport material downslope. To show differentiation of flow-like landslides, the author selected six forms observed in the Bukowica Range. The character of flow depends mainly on liquefaction and volume of transported material, as well as on land relief. Keywords: flow, slide, complex landslides, Bukowica Range, flow-like landslides.
