Odbicie ekstremalnych wezbrań okresu historycznego w osadach rzecznych i stokowych w dorzeczu górnej Wisły

Reflet des crues extrêmes de la période historique dans les dépôts fluviatiles et de versant de la haute vallée de la Vistule

Description :
Besides the measuring records, chronicles and old maps, the flood records are reflected in the slope and fluvial deposits and forms. We may distinguish several phases of increased fluvial activity connected with climatic variations and changes in the land use. On the medieval forest clearence are superimposed heavy floods from the second half of XIth century and close of XIIIth century. Frequent floods from XV-XVIth century and snow melt floods of the Little Ice Age caused the shift of the meandering toward braiding channels. Again the late XIXth century regulation is reflected in the turn from aggradation to erosion. The separation of the climatic factor from the anthropogenic one needs more extensive research. - (DG)
