A numerical model for hydrodynamics and sediment transport is applied to Mont Saint Michel Bay, where ecological concerns are related to sediment transfers. Recent current datasets recorded on the tidal flat show the wind influence on the currents during neap tide. They are compared to model...Contributeur (s):

Cayocca, Florence - 1996The Arcachon tidal inlet exhibits a particularly active morphology due to strong tidal currents and rough wave conditions. During the past 300 years, maximum and minimum extents of the Cap Ferret sand spit have resulted in a difference of 8 km while two channels have alternatively allowed...Contributeur (s):

Bonnot-courtois, C / Bassoullet, Philippe / Tessier, B / Cayocca, Florence / Le Hir, Pierre / Baltzer, A - 2008In order to define and quantify the rhythm and amplitude of the processes of erosion and sedimentation on broad tidal flats, in situ measurements of sediment elevation have been performed in the western part of the Mont-Saint-Michel bay. The amplitude of reworking is generally low (< ± 5 cm),...Contributeur (s):

Batifoulier, Francois / Kervella, Youen / Laborde, Renaud / Cuny, Jérôme / Caillaud, Matthieu / Lazure, Pascal / Cayocca, Florence - 2012Les fortes vitesses rencontrées à l’entrée de la Baie du Mont Saint-Michel font de cet environnement macro-tidal un endroit privilégié, en termes de ressources énergétiques, pour l’implantation d’une ferme d’hydroliennes. Afin d’établir plus précisément son potentiel énergétique et d’évaluer l’...Contributeur (s):

Sur de nombreux sites ostréicoles, d’importants mouvements sédimentaires modifient les conditions d’exploitation. Les mouvements naturels sont modifiés par la présence des tables à huîtres, les phénomènes en jeu étant de deux ordres : la perturbation des courants de marée et la modification des...Contributeur (s):

Fossati, Monica / Cayocca, Florence / Piedra-cueva, Ismael - 2014This paper investigates the main characteristics of the fine sediments dynamics in a very complex and extensive inner shelf area located in South America, the Río de la Plata. The results derive from a 5 yr international research program that allowed intensive data acquisition throughout the area,...Contributeur (s):

Gaurier, Benoit / Germain, Gregory / Kervella, Youen / Davourie, Julia / Cayocca, Florence / Lesueur, Patrick - 2011Shellfish farming, particularly oyster farms, suffers from strong siltation phenomena which are harmful to the production of shellfish. The lack of knowledge about the impact of an oyster farm on the wave propagation and on the flow remains a significant difficulty for the comprehension of sediment...Contributeur (s):

Le Hir, Pierre / Cayocca, Florence / Waeles, Benoit - 2011Mixed sediments are constituted of cohesive and non-cohesive materials with distinct behaviours that numerical models traditionally manage separately. This paper first introduces a rapid state of the Art in sediment transport modelling in order to point out the specific requirements for process-...Contributeur (s):

Kervella, Youen / Germain, Gregory / Gaurier, Benoit / Facq, Jean-valery / Cayocca, Florence / Lesueur, Patrick - 2009Oyster tables are artificial obstacles which are laid over muddy or sandy-muddy floors in intertidal areas. This study aims to show the current modifications related to the presence of the oyster table thanks to LDV measurement in a flume tank. Boundary layer development in different geometric...Contributeur (s):
