Brun, Jean-Marc. "Modèles à complexité réduite de transport pour applications environnementales". Montpellier 2, 2007. http://www.theses.fr/2007MON20248.
Texto completo da fonteA platform of low complexity models for the transport of passive scalars for environmental applications is presented. Multi-level analysis has been used with a reduction in dimension of the solution space at each level. Local spray drift distribution is estimated thanks to the turbulent jet theory and determine the source term. Similitude solutions are used in a non symmetric metric for the transport over long distances. Model parameters identification is based on data assimilation. The approach does not require the solution of any PDE and therefore is mesh free. The model also permits to access the solution in one point without computing the solution over the whole domain

Texto completo da fonteThe study was performed experimentally. The vortices are generated by interaction between a monochromatic wave and a horizontal thin plate used as vortex generator. Their characterisation has been done in two and three dimensions. The two-dimensional vortex dynamics is characterized using PIV measurements. We observed the formation of downstream and upstream vortex pairs which are mutually advected toward the flume bottom and the free surface respectively. These evolutions are characterised through mean vortex trajectories computed thanks to λ2 criteria. It shows the presence of two stagnation point at the flume bottom due to the vortex pair advection and to the presence of two adjacent recirculation cells under the plate. These points would be a location of scouring phenomenon in the case of a sea bed. The three-dimensional vortex destabilisation has been studied thanks to the stereo-videography. The vortex cores are visualised with hydrogen micro bubbles generated at the edges of the plate by electrolysis. The deformation modes study, using a Fourier and a wavelet analysis, revealed that the deformation modes vary over the wave period. Strong axial velocity had been visualised on the vortex cores from the beginning of their development. These velocities are characteristics of strong destabilisations and vortex bursting

Texto completo da fonteAtmospheric pollution due to agricultural pesticide for viticulture is a major concern today, regarding both public health, sustainable agriculture and ecosystems quality monitoring. Atmospheric dispersion modeling and the use of geographic information systems allow us to spatially quantify the atmospheric pollution on a given area. This thesis is based on the coupling of an atmospheric dispersion model and a geographic information system, in order to predict and map atmospheric pollution after pesticide spraying applications. Implementations of digital elevation models and scale changes into the reduced order modeling are described and illustrated. The resulting simulation platform is presented as a Quantum GIS software plugin, thus exploring the Open Source GIS capabilities to implement complex physical models. The platform is finally used on a typical Souther French wine-growing area, and a pollution risk analysis scenario is proposed

Texto completo da fonteThis work investigates two research questions associated with environmental flows and their mathematical modeling.The first part is devoted to the development of finite volume methods for anisotropic and heterogeneous diffusion operators arising in models of porous media flows. To ensure that the approximate solutions lie within physical bounds, we aim at maintaining a discrete analogous of the maximum principle for elliptic operators. Starting from any given cell-centered finite volume scheme, we present a general approach to devise non-linear corrections providing a discrete maximum principle while retaining some main properties of the scheme. In particular, we study the coercivity and convergence properties of the modified schemes.The second part of this work focuses on the derivation of approximate models for shallow water wave propagation over rough topographies. In the particular case of one-dimensional polygonal bottom profiles, we first propose an adaptation of the usual derivation method using complex analysis tools. We then develop a formal approach to account for more general topographies. We propose nonlocal alternatives to some classical models (namely Saint-Venant equations, Serre equations and Boussinesq system). All these alternative models only involve smoothing contributions of the bottom

Texto completo da fontePrevious studies have shown the notable impact of Offshore Wind Farms (OWFs) on the local and potentially regional environment. Indeed, the foundations of wind turbines serve as artificial habitats for a variety of benthopelagic species, thus creating a reef ecosystem. Additionally, the hydro-sedimentary environment near the foundations is altered with the introduction of sheltering effects, turbulent wake, scouring, and ridges, for example. This study focuses on investigating the hydrodynamic effects of the parks on larval dispersion in the extended Seine Bay. The impacts of the parks on the dispersion of both natural species (e.g., mussels and European green crabs) and introduced species (e.g., Japanese oysters and Asian shore crabs) are studied through a coupled physical-biological approach based on numerical modeling. The local scale around a single foundation or a cluster of foundations and then the regional scale of the extended Seine Bay (from the Franco-British maritime border to Hauts-de-France), including OWF of Courseulles-sur-Mer and Fécamp, have been examined. At this scale, the hydrodynamic effects of the foundations vary depending on their type and spatial arrangement. Dispersion simulations highlight a notable sensitivity to foundation geometry and the angle of incident current relative to it. At the regional scale, simulations have underscored their potential role as relay points for species. Larval dispersal from the wind farms has also shown connectivity between the parks themselves and the shores of the extended Seine Bay. To enhance the consideration of physical and biological realities in simulations, the integration of realistic biological parameters is beneficial, as well as considering the cumulative effects of multiple structures within offshore wind farms

Texto completo da fonteLime and/or cement stabilization is a common solution for improving the mechanical performance of fine soils. Treatment limits the shrinkage and swelling effect of clayey soils. However, while numerous laboratory studies have been carried out on treated materials, little is known about the in situ performance of such stabilised materials several years after construction, and very few studies are available, especially in the case of stabilised expansive soils. As a result, existing methods and procedures are generally unable to assess the alteration caused by the environmental conditions of a treated soil. This thesis addresses these issues by studying an experimental embankment at Héricourt (France). Built in 2010 as a part of the ANR TerDOUEST project, this embankment was built with a highly plastic clayey soil. The clay was treated with lime and/or cement upon construction. An initial assessment of the state of the backfill was carried out 11 years after construction of the structure, with horizontal and vertical corings. The hydromechanical characterisation of the treated clay was carried out with multiple oedometer tests. The compressibility of the material sampled by horizontal coring was determined, making it possible to assess changes in the mechanical behaviour of the treated soil as a function of its proximity to the edge of the embankment. The results showed that the materials located in the internal part of the embankment have a mechanical behaviour similar to that of the soil treated in the laboratory after a 180-day curing time at constant moisture content. On the other hand, a gradual deterioration of the mechanical properties of the material was observed as it approached the outer part of the embankment. The mechanical properties of the materials taken from the outer part were equivalent to those of the untreated soil. The microstructure (mercury intrusion porosimetry, scanning electron microscopy), chemical composition (thermogravimetric analysis, X-ray fluorescence) and mineralogical composition (X-ray diffraction) of the treated soil were studied in order to understand the environmental conditions responsible for the deterioration observed at the edges. Leaching from the treatment was identified as being partly responsible for the decrease in mechanical performance measured at the edge of the structure. Mineralogical transformations, such as the formation of calcite in the first few metres of the backfill, also highlighted an alteration of the hydromechanical behaviour through carbonation of the cement phases. The role of wetting and drying periods in the mechanical weathering of the treated soil was also studied. Specimens from the inner part of the structure were subjected to wetting and drying cycles of various suctions ranging from 0 to 95 MPa. The results showed that drying and wetting cycles have a major impact on the long-term performance of treated soils above a certain suction amplitude. The degradation process is mainly a consequence of cement bond failure rather than other physico-chemical processes such as calcium leaching or carbonation. This study allowed a mechanical quantification of the weathering of treated clay taken from an experimental structure. Leaching and carbonation during treatment were identified as being responsible for the deterioration in mechanical performance in the external part of the structure. The study of the treated material subjected to hydric cycles allowed to quantify their impact on mechanical behaviour, while determining the mechanisms by which the effects of the treatment were altered
