Webb29 nov. 2024 · 1 Introduction. The elemental composition of river sediments is determined by the chemistry of the eroding substrate (e.g., bedrock and soils) and modified by processes including chemical weathering, cation exchange, and hydrodynamic sorting (e.g., Bouchez et al., 2011, 2012; Lupker et al., 2016).Consequently, river sediment … WebbWhile Table 1 gives the erosion rates for continents as a whole, the sediment yield from individual river catchments varies from as little as 1ton/km2/year to as much as 50 000 tons/km2/year. The various factors which affect sediment yield are discussed by Walling.
