Synopsis:

Tidal cycles in turbulence, current velocity and salinity are compared with near-bed mud suspension characteristics through in-situ measurements of floc settling velocity, size and mass concentration. The complex nature of flocculating suspensions results in lags in the response of sediment properties to local forcing mechanisms which has important implications for residual flux magnitudes and directions. This study will examine the phase relationships between floc settling velocity, size and density, suspension concentration, turbulence and velocity in an estuarine environment and use the results to estimate transport and deposition rates as well as net fluxes over a tidal cycle.
