Popis:	It is now widely recognized that significant proportion of pollutants in rivers is transported with suspended sediments. This paper presents a combination of reconstruction of recent floodplain sedimentation rates based on detailed description of sediment sections and 137Cs stratigraphy with geochemical analysis of overbank deposits at selected sites on rivers of the Severnaya Dvina River basin. Overbank sedimentation rates for sections sampled on floodplains of the Severnaya Dvina and Vychegda Rivers are characterized by noticeable decrease from ≈1.5–4.0 cm/year between 1954 and 1963 to
