Les matieres en suspension dans les estuaires

This paper, devoted to the behaviour of suspended matters in estuaries, deals successively with:

- the nature and origin of sediments suspended in some estuaries

- the behaviour of suspended materials: flocculation, falling rate of flakes, shrinkage, rheology, picking up by currents, slides inside the deposits

- the sedimentary movements of floating materials in the estuaries: transport under the influence of the tides, sedimentary materials available in the estuary, influence of the river discharge and of the salinity, ejection of suspended matters out of the estuary,

- volume of the deposits in some estuaries.
