The cohesive sediment dynamics must take into account the consolidation processes which brings dry bed density variability in time. ln this paper. a state-of-the-art concerning consolidation models commonly used in sedimentary dynamics is given. os weil as. a review of the soils mechanics consolidation theories. The boundary between sedimentation and consofjdation is defined. and similitude laws correlating prototype and laborotory data ore presented. Based on theoretical aspect. a consolidation model is developed, ln this model. dry density C. characterize material state. The permeability and the material behaviour ore only depending on the dry density. The material behaviour is simulated by a rigid-plastic model, Consolidation tests of a mud (from the estuary of the Loire river) are carried out into laboratory. Tests results ore used to adjust and check the validity of the proposed mode!.
Pour étudier une zone côtière aux fins d'aménagement, un éventail important de technologies a été mis en oeuvre : sondage hydrographique, géophysique marine, cartographie par plongée, mesures de houles, de courants, de marées, corrélation houlemétéorologie, dragages et carottages, analyse physique et chimique des sédiments. C'est l'utilisation d'un modèle mathématique de transport des sédiments, DIAMAX, qui a permis de faire une synthèse des divers résultats. TI en est sorti deux enseignements scientifiques : l'un concernant la géologie du quaternaire, l'autre concernant l'océanographie de la zone NORD-GASCOGNE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
