The study discusses the development of a montane river channel under anthropopression. Cartographic analysis and examination of historical records provided basis for reconstruction of the course and pattern of the submontane Skawa river channel in the 18th and 19th century, when the area was only slightly affected by anthropopression. Review of technical literature enabled identification of the main periods of river rectification, resulting in disappearance of the multiple channel. Present day geomorphological mapping indicated sites of reappearance of wandering channels, overlapping areas in which they functioned in the 19th century. Transformation of the Skawa river channel from multiple to single is a consequence of long-term hydrotechnical works.
