The study of suspended solids in the West Siberian rivers is of great importance from the point of view of biogeochemistry, since in the rivers there are the formation and transformation of abrasion products of banks and bottom, suspended and dissolved organic matter and solid river flow, which are carried out from the land to the Kara Sea and further to the North Arctic Ocean. Studies of river suspension are necessary to understand the processes of modern sedimentation, as well as for the ecological assessment of the water area state. Mechanisms of sedimentation are largely associated with the processes of physical and biological weathering, generation, transformation and transport of suspended matter from the catchment to floodplain landscapes. In this regard, the role of studying the connection of the qualitative composition of river suspended matter with landscape parameters (level of the catchment area swappiness, nature of the soil cover, composition of soil-forming rocks, presence (absence) of permafrost, etc. is high. For example, the river of the north-taiga subzone, the catchment area of which is heavily swamped, and the river of the tundra zone with a slightly swampy watershed are represented. The influence of flood waters on the concentration of some elements in rivers with contrasting watersheds is considered. The contribution of groundwater and the effect of soil solutions on the overall migration flow are estimated.
