Significance of the hydraulic control for the metal partitioning within river as well as explains spatial (inter-basin) variations in particulate flux due to local hydrology, erosion rates and catchment lithology. Hydrogeochemical model to derive the annual flux of the sediments and particulate flux of the selected metals using (ADCP) acquisitions with sediment depth profile sampling of the Ob, Enisey, Lena and Kolyma Uncertainties estimates in selected sediment quantity and quality data, including contributions from vertical and cross-sectional variations into fluxes estimates including requirements for sampling strategy. Novel quantitative assessment of bank and catchment erosion contribution into chemical flux.
