Contributions des traceurs radioactifs a l''etude des mouvements sedimentaires en Baie de Seine
Provedor de dados: 5
Autores: Avoine, J; Caillot, A; Hoslin, R; Larsonneur, C; Massias, L; Quesney, M.
Sediment dynamics have been studied from 1979 to 1984 by the use of radio active tracers, to quantify sediment transport and to know the limits of tides and swell action in terms of sediment composition and depth. This technique has allowed the study of sand drifting (between -2 m and -15 m) and resuspension of muddy sediments. The effects of sediment movements on estuarine sediment accumulation are included in this report.

Dynamique des suspensions et des depots: Synthese des discussions
Provedor de dados: 5
Autores: Larsonneur, C.
During the debate, the observations have dealt with balance-sheets, swell influence, sediment movements, and sedimentation flow deducted from suspensions studies. General remarks have been formulated, and a distinction of main fluvial mouths in the French littoral have been suggested.

La dynamique sedimentaire dans les estuaires de la Baie de Seine. Consequences sur l''environnement
Provedor de dados: 5
Autores: Avoine, J; Dubrulle, L; Larsonneur, C.
Tides and fluvial flow rate, factors of estuarine dynamics, explain physicochemical and biological properties, silting and clogging of these environments. Seine Bay is a macrotidal environment into which discharge several estuaries (Seine, Orne, Veys Bay). After speaking about the characteristics of water and sediment dynamics, the authors deal with the effects of man-made modifications and the necessity to protect the environment.

Transports solides sur les plages macrotidales : traçage fluorescent et application à la côte ouest du Cotentin (France)
Provedor de dados: 5
Autores: Levoy, F; Monfort, O; Larsonneur, C.
Fluorescent tracers, often used to study longshore transports induced in the breaking zone, are here adapted to the multidirectional movements observed on macrotidal beaches, where sediment transports are dominated by wave or tide action or by the simultaneous action of both. The relative influences of these agents vary in space and time. Different techniques of quantifying fluorescent grain concentrations, by surficial or volumetric counting of samples are tested and compared. The automatic counting of fluorescent grains present in the mobile layer is also tested and validated. Comparisons, made during a preliminary experiment, between concentrations evaluated in this manner and values inferred from visual inventories are satisfactory. The different...
