An attempt of denudational volume and rate estimation under forest-steppe at the Russian Plain

Abstract

The total erosion at the Seim River basin (Middle Russian Elevation) has been estimated by calculation of the volume of concave erosional landforms. Coefficient of denudation, i. e. volume of eroded rocks to total volume of valley and interfluves ratio is equal to 0,54, which indicates the maturity of the relief under consideration. Erosion rate calculated for Neogene and Quaternary appeared to be 0,028 mm per year, the value being close to the contemporary solid discharge of the Seim River (0,026 mm per year).
