The AA. report on the development of a multi-proxy flood history for the River Tay, Scotland, drawing on the sediment archive of a major palaeochannel complemented by archival, historical and epigraphic flood records from the city of Perth
. This paper demonstrates that proxy flood records extending over 200 years can be successfully recovered from sediment stacks in palaeochannels adjacent to major rivers. The hypothesis that each local coarsening in the stack represents a flood signature which

From its origins as a geological study of flood erosion and sediments the science palaeoflood hydrology matured to become an indispensable means for understanding the hydrology of very large, rare floods. Such floods are increasingly posing risks

A database of radiocarbon dates from Late Holocene fluvial environments in Spain was critically analysed in order to obtain a fluvial chronology for this period. The principal types of depositional represented in the record were slackwater flood
regions slackwater flood deposits are valuable archives of climatic variability even during periods of increased human impact.

This paper offers an alternative to the use of geomorphological and sedimentological evidence for the reconstruction of flood and low flow frequencies. It is based on a technique developed to estimate the hydrological impact of future climate change

A comprehensive database of radiocarbon dated fluvial units in Great Britain, Poland and Spain has been compiled to investigate the relationship between environmental change, flooding and Holocene river dynamics. Data analysis has been undertaken

and the evolution took place only in the one active branch (valley). Only young terraces are preserved in the section between Orsha and Shklov : low Vistulian-Young Pleniglacial terraces and two levels of the Late Glacial-Holocene flood plains. With the large
horizontal stability of the channel, the modelling of flood plains resulted only form a vertical accretion of overbank deposits. Phases of the intensified activity of the Dneper which have been identified on the border of the Atlantic and Subboreal and during
the Subatlantic about 2100 and 1000 BP manifested themselves here by changes of the type of sedimentation on flood plains (buried soils). These phases are conditioned by the climate, altough in the younger one a remarkable influence of human activity is evident
. The A. distinguish the effects of heavy downpours, continuous rains and extreme rainy seasons, as well as snowmelt floods visible in transformation of slopes and river channels. This examination shows a random distribution in 20-th century with few clusterings
