Última Suspended sediments in a macrotidal estuary: comparison and use of different sensors ArchiMer Lunven, Michel; Gentien, Patrick. Measurements made using an in situ particle-sizer (PSA) were compared to those of an optical backscatter sensor (OBS) in a macrotidal estuary. Both estimate the total volume of particles. After comparison with dry weight of suspended matter sampled in the study area, the different measurements were converted into dry weight. In three different kinetic energy regimes, times series were coherent for most of the observations. Discrepancies of suspended sediment concentrations estimated by both sensors appeared under specific hydrodynamic conditions: they were related to occurrences of definite particle populations. Overestimations and underestimations of measurements by the instruments depend on the optical principles of the sensors (backscatter and...
