The Vistula River is a typical Central-European river flowing from the mountains acrossbasins and upland belts to the lowlands. The Vistula valley is modelled by a river with a complexhydrological regime. In its upper reaches, floods driven by summer rainfall prevail, while in thelower reaches snowmelt floods are important. Deforestation favoured a natural propensity forriver braiding. In the mid-19th century, the channelization of the upper Vistula (in the Carpathianforeland) and the lower reaches was commenced with, while the middle streach was leftin a natural state, such that the river has in places preserved a braided pattern up to the presentday. The channelization followed by construction of reservoirs caused downcutting and aggradationto occur, such that opposing tendencies were observed in particular reaches of the riverchannel. In addition, flood embankments confined aggradation to the intra-embankment area.Thus, the functioning of the Vistula River system is largely controlled by diverse human activity.Unconstrained flow and river load transport along the whole river length are only partly possibleduring extreme floods. The present-day adjustment tendencies also relate to ongoing changes inland-use in the drainage basin, as well as on global climatic changes.
