Quantitative assessment of alluvium made by water and wind from field surface of the reclamation systems is presented, its redistribution and accumulation in open drainage system by application of the existing techniques is made. The estimation techniques of reclaimed peat soils erosion damage level upon analog objects in the context of typical soil and climatic conditions of the Republic of Belarus including ageing treatment of reclamation systems are developed. The scheme of the experimental lot of reclamation system and silting volumes of canals cross sections is presented. The scheme of solid flow formation on the canal section is displayed. Textural curve of the bottom alluvium sediments is shown. Calculation of average hydraulic granularity of alluvium is made. The scheme of channel operation regime per average year is suggested. Intensiveness of organic matter content decline is evaluated. Deprivation of organic matter due to the flat erosion is shown. Distribution of the erosion products from the field over the experimental area is presented. Complex impact of water, erosion and deflationary processes on components of open reclamation system is estimated.
