The forest-steppe landscapes on the east of the Russian Plain possess favourable agro-climatic resources. The evaluation of the suspended sediment yield was performed for the rivers' basin of the East Russian Plane. The following aspects of the subject were being studied: examination of the calculated values of suspended sediment yield in the small rivers' basins on the mathematical -statistical model of the sediment load; building the map of spreading the sediment yield; studying the suspended

... sediment yield spatial trends in the small rivers' basins. The study area is located within the forest, forest-steppe and northern part of the steppe landscape of the Russian Plain and comprises more than 130 000 km . The calculated values of sediment 2 yield module for each of 3331 basins of the examined territory were calculated.
