Texto completoThis doctoral research focuses on water level variations in semi-open coastal basins and the impact of wind, waves and bathymetry. The two phenomena causing water level variations studied are wind-tides and seiching. Three coastal basins were selected on the French coast of the Provence-Alpes-Côte d’Azur region˸ the Vaccarès lagoon, the Berre lagoon and the Toulon Bay. The choice of these sites is due to the fact that they are exposed to equivalent wind regimes, their depths, morphologies and openings to the seaare different, allowing a comparative analysis. This work is based on the use of in-situ water level data from the HTM-NET network and two experimental campaigns. It was shown that the higher the wind speed, the steeper the slope of the free surface. Wind-tide is all the more important as the depth of the basin is low. In addition, the greater the opening to the sea, the lower the wind-tide. The determination of a constant drag coefficient allowed a satisfactory prediction of moderate wind-tides. It was also observed that in basins of finite depth and limited fetch conditions, the wave conditions are responsible for a higher wind friction on the water surface. The analysis of the currents showed that the presence of wind-tides has an impact on the currentology in the three sites. The periods of the seiches in the three sites were determined and the axes of resonance could be partly identified. The seiche amplitudes are of the order of mm in the Vaccarès lagoon and cm in the Berre lagoon and the Toulon Bay. The high friction in theshallow water site is responsible for an attenuation of the seiche amplitudes. The presence of seiche was correlated with wind-tides in the Berre and Vaccarès lagoons, which have a moderate opening to the sea. On the other hand, in the Toulon Bay, which has a large opening to the sea, other forcings are likely to excite the natural modes

Texto completoThere has been quite an intense development of traditional industries around the « étang de Thau », the largest lagoon in the Gulf of Lions. Of these, fishing and shellfish farming make up what is nowadays known as the “small enterprises” of the lagoon. In an undefined category that is not quite a micro society, this community has managed, thanks to its great vitality, to adapt to changes in the socioeconomic context. Since settling on the shores of the lagoon they have had to overcome a lot of problems – linked to the climatic environment, fishing, fish-farming techniques and the usual disputes. Difficulties arise from the new redefined role of women in production, from the sharing of space and resources and from the various phytosanitary crises. These constraints do not prevent shellfish lovers from paying their homage by organising religious ceremonies, games and festivities all around the lagoon. When the party is over, no one can forget the ever-present tensions between a constantly expanding human activity. In order to preserve the quality of the environment while satisfying the requirements of all users, some professionals have joined forces to get round a certain number of intermediary social organisations that do not have their total confidence. Their knowledge of issues relating to the use of the area has allowed them to take a stand in managing disturbances - particularly those brought about by continually increasing numbers of people using the lagoon. In this way, they have managed, insofar as is possible, to preserve the resources of the lagoon, and ensure the survival of the “little jobs”

Texto completoThe toxic blooms of Alexandrium catenella in Thau lagoon (France) are related to paralytic shellfish poisoning syndrome. Understanding and predicting their developments depend on the identification of the seeding pattern and potential "hot spots" for bloom initiation. Mapping reveals three preferential zones for resting cysts accumulation which are linked to hydrodynamism. Low resting cyst density in sediments is related probably to a new invasion process. However, higher densities linked to a patchy distribution mode are recorded in the creek of l’Angle which is considered as a significant hot spot for bloom initiation. Bloom recurrence results from cyst survival in sediments, whose renewal depends on the encystment phase. The germination of A. Catenella resting cyst does not depend on light and nutrients in the culture medium. High rates of excystment and synchrony occur in a large "environmental window" (temperature and salinity). However, the low realized seeding ratio limits significantly the initiation phase. The confrontation with numerical simulations suggests that a short duration of water column stability/confining period associated with a frontal structure reduces dispersion, supports the cohesion of bottom cell clusters and allows the seeding population to reach a critical density as a condition for successful bloom initiation

Texto completoThe studied site is the Vaccarès hydrosystem, the central part of the Rhône delta and a good example of strong relationship between humans and a natural area. Through the data acquisition and data processing, we characterised the hydro-saline dynamic of this complex hydrosystem from 1993 to 2008. From a further analysis, we established first the hydro-saline and sedimentary balance across the lagoon complex. Through a monitoring of 16 years, the sedimentary balance revealed a sediment deficit of about 19'500 tons when we disregard the outstanding contributions of flooding waters in 1993 and 1994. If this deficit persists, the difference in altitude between the sea and the delta will tend to increase. This will result by a salinization of the system, unwanted by the most of his actors. To investigate these consequences, we conceived a hydrodynamic model of the Vaccarès lagoon complex, capable to simulate water levels and salinities. The model, named Hydro-CAM, was calibrated and validated in terms of water levels and salinities in three sub-units of the lagoon complex. It was then used to test the system dynamics in a prospective approach. The objective in this thesis work was to explore by simulation the possible trajectories of the evolution of the Hydrosystem in terms of water and salt balance. Simulations were based on scenarii constructed from climate parameters and anthropogenic parameters (water management, constructions, land use on drainage basins, etc.). The results revealed the vulnerability of this complex system to various risks which it is already facing and for which the intensification and/or increase can be expected in the future
