Résumé

Cet article, consacré au comportement des suspensions dans les estuaires, examine successivement:

  • - la diversité, la nature et l'origine des sédiments en suspension dans quelques estuaires,

  • - le comportement des suspensions: floculation, vitesse de chute des flocons, tassement, rhéologie, conditions de reprise par les courants, glissements des dépôts,

  • - les mouvements sédimentaires en suspension dans les estuaires: transports sous l'action des marées, stocks sédimentaires disponibles dans l'estuaire, influence du débit fluvial et de la salinité, expulsion des suspensions en dehors de l'estuaire,

  • - i'importance des dépôts dans les estuaires.

Abstract

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.
