On the rate of alluviation of the Upper Volga drainage basin

Abstract

Calculations based on data of archaeological studies of the Voyatitsa site on the Sheksna River indicate gradual' decrease in alluviation rate with the age of the floodplain: from 0.7 m per 1000 yrs in the 3rd millennium BC to 0.4 m per 1000 yrs after the middle millennium BC. A relative increase in the floodplain surface height, above the water edge results from both sedimentation on the surface and downcutting of the river.
