(Nonuniform vertical distribution of fine sediments in Amazonas rivers.). Academic Article uri icon


  • Sediment particles finer than 60 mu m are not uniformly distributed in suspension in waters of the Amazon and Solimoes Rivers. Concentrations of such fine particles at the river surface are only half as large as their concentrations in the full water column. Particles as small as 10 mu m are less concentrated near the river surface than at greater depths. Estimates of sediment yield and flux of suspended chemical constituents that are based only on surface samples are likely to contain significant errors.
