Raconter l’espace en jouant avec le temps. Exemple d’un exercice participatif de géoprospective des pêches maritimes ArchiMer
Tissiere, Laurie; Michel, Charlotte; Mahevas, Stephanie; Trouillet, Brice.
Prospective studies considered that the future is not determined. Time is then a lever to enhance debates. More recently, << geoprospective >> has integrated space in discussions about possible futures. That questions directly the functions of the spatial and the temporal dimensions, especially the capacity of space and time to play as intermediaries for participation. We applied this question on the case of a fishery in the Bay of Biscay. On the one hand, we demonstrated that the participative method, combining qualitative and quantitative approaches, as well as simple and complex tools, allowed to describe the stakes of the case study and to imagine spatially-explicit possible changes. On the other hand, we also pointed that space and time...

Les pêches maritimes : un terrain d’expérimentation de la géoprospective ArchiMer
Tissière, Laurie; Mahévas, Stephanie; Michel, Charlotte; Trouillet, Brice.
A prospective approach can be used to establish management and environmental protection options to stimulate discussion and bring different scenarios for the future into perspective. This future-oriented process incorporates spatial dimensions with the development of a geoprospective approach. Indeed, a geoprospective approach highlights geographical dynamics and integrates spatial perspectives into the debate. A participatory framework for analyzing the marine fisheries sector has two main advantages. The first is academic, in that it helps to establish a methodological and epistemological corpus based on geoprospective. The method proposal allows, on the one hand, to discuss the purpose of the models and, on the other, to explore the role of researchers...

Morphodynamique et transferts sédimentaires au sein d'une baie mégatidale en comblement (Baie de Somme, Manche Est). Stratégie multi-échelles spatio-temporelles ArchiMer
Michel, Charlotte.
The Baie de Somme is an infilling estuarine environment, controlled by intensive marine hydrodynamics forcing (megatidal tide and waves) and a small river flow. Morpho-sedimentary dynamics of this bay and sedimentary fluxes were studied at two spatial and temporal scales. I) At the scale of intertidal hydraulic dunes, studied during semi-diurnal and semi-lunar tidal cycles with neap tides (NT) and spring tides (ST). In this context, a strong forcing variability (winds, tide, waves) control sedimentary fluxes and morphodynamics evolutions of dunes (λ : 5-23 m ; H : 20-60 cm). These fluxes generally increase with tide and waves, inducing a net sediment transport to the east or west, according to the predominance of current (flood/ebb), which depends on the...
