This paper reports the use of sediment cores collected from river floodplains to provide information on changing suspended sediment sources and sedimentation rates at 7 sites within the non-tidal component of the catchment of the River Ouse, and one
). Caesium-137 analysis of floodplain sediment cores has been used to estimate average rates of overbank sedimentation during the last 30 to 40 years. The residence time of the fine-grained sediment stored on the channel bed is probably less than one year
