  abstract = {{O}ver the past several decades, major hydro-sedimentary changes have occurred in both continental and coastal regions of the {M}ekong {D}elta, and this has severely impacted coastal erosion. {A} good characterization of floc properties and of their changes over time is necessary to gain comprehensive understanding and modelling of hydrodynamics and of the associated geomorphological changes. {T}his paper quantifies the influence of sediment concentration, turbulence and differential particle settling on flocculation through field and laboratory investigations of the {M}ekong estuary. {F}or concentrations lower than 200 mg.{L}-1, the particles do not exhibit a dynamic response to their environment, while for higher concentrations (up to 3-4 g.{L}-1), particle size and settling velocity increased by more than one order of magnitude. {F}locculation by differential settling has not been sufficiently investigated yet, but this study reveals it as a predominant factor for siltation in quiescent environments such as the ones existing in the inner mangrove fringe. {S}uch results are important to provide realistic simulations of the coastal evolution.},
