ИСТИНА

Soil erosion totals can be dominated by a few extreme events, thus monitoring, as well as erosion model simulation need to be long enough to capture these erosive events. The land use and climate changes are also influenced on the average erosion rates. Quantitative assessment of erosion rate trends for the last 5 decades was undertaken for the Veduga River and the Mesha river basins, located in two regions of the Russian Plain (Voronezhskaya oblast’ and Tatarstan Republic respectively). The both river basins are located in the forest-steppe zone with very high proportion of croplands (. Detail assessment of erosion rates was done for two time intervals (1963-1986 and 1986-2015) in the middle scale for the studied river basins. In addition, the soil redistribution for period 1963-1986 and 1986-2015 were studied in one small catchment within each river basin for the verification of model calculations.
