Аннотация:The detail assessment of geomorphological and radioecological consequences of the extreme flood in the Niida River basin allows to conclude that different exogenic processes (landslides, scree, bank erosion etc.) were the main sediment sources for the river sediment discharge. Maximum channel deformations were observed within the lower reach of the Niida River because of extremely high energy of the stream with maximum water and sediment discharges. However, sedimentation rates on the floodplain of the upper reaches of the Niida River were also one order higher under the mean annual rates. Finally, extreme event promoted to the serious reduction the dose rate of the river bottom except some high floodplain levels where sedimentation rates were negligible.
