  abstract = {{A}ccurately measuring sediment flux in large rivers remains a challenge due to the spatial and temporal cross-sectional variability of suspended sediment concentrations in conjunction with sampling procedures that fail to accurately quantify these differences. {T}his study presents a field campaign methodology that can be used to improve the measurement of suspended sediment concentrations in the {A}mazon {R}iver or similarly large rivers. {T}he turbidity signal and {R}ouse model are together used in this study to define the spatial distribution of suspended sediment concentrations in a river cross-section, taking into account the different size fractions of the sediment. {W}ith this methodology, suspended sediment fluxes corresponding to each sediment class are defined with less uncertainty than with manual samples. {T}his paper presents an application of this methodology during a field campaign at different gauging stations along a 3,000-km stretch of the {S}olimoes/{A}mazon {R}iver during low water and flood periods. {V}ertical concentration profiles and {R}ouse model applications for distinctive sediment sizes are explored to determine concentration gradients throughout a cross-section of the river. {T}he results show that coupling both turbidity technology and the {R}ouse model may improve our understanding of the spatial distribution of different sediments fractions sizes in the {S}olimoes/{A}mazon {R}iver. {T}hese data are very useful in defining a pertinent monitoring strategy for suspended sediment concentrations in the challenging context of large rivers.},
