Hydrological alteration within an ice-marginal valley is analysed in relation to flooding by the River Vistula flowing within that valley. Specifically, the analysis covers the period of the last two centuries (up to the present day), making reference to human impacts and natural disasters. Seven topographic maps, as well as digital terrain model (DTM) analysis of the extent of flooded areas are used to evaluate the linkage with historical flood events. Within the ice-marginal valley, flooding processes are found to still play an important role on the floodplain, although human activities have limited these significantly through the construction of embankments. The changing characteristics of floods generated by different mechanisms (e.g. heavy rainfall and ice jams) are also discussed.Editor D. Koutsoyiannis
