WebHere we present continuous, concurrent observations of dynamics and suspended particulate matter (SPM), performed in the bottom boundary layer (bbl) of a macrotidal estuary during a 24-day period. Turbulence parameters were found to vary on both a quarter-diurnal and a spring-neap tidal timescales. Webprocess of salt flocculation. Measurements by EISMA (1991) conducted in the Zaire River estuary indicated that salt flocculation did not appear to be an important cohesion mechanism for the formation of in-situ floes, principally due to the weak nature of the electrostatic bonds.
