Development of a data-driven distributed hydrological model for regional scale catchments prone to Mediterranean flash floods. Application to the Ardèche catchment, France / Développement d'un modèle hydrologique distribuée construit à partir de l'analyse des données pour la modélisation régionale des bassins Méditerranéens soumis aux crues rapides. Application au bassin versant de l’Ardèche. France

Adamovic, Marko 05 December 2014 (has links)
L'objectif scientifique de la thèse est de progresser dans la modélisation hydrologique spatiale régionale dans le contexte de crues éclairs qui représentent l'une des catastrophes naturelles les plus destructrices dans la région Méditerranéenne. L'accent est mis sur les questions de mise à l'échelle des bassins versants et la dérivation des équations et des modèles applicables aux bassins de milieu simplifiées de grande taille pour mieux décrire l'hétérogénéité du paysage et de la complexité du processus. Telles sont les questions clés pour faciliter le modèle mis en place dans le contexte de l'ensemble du bassin versant et d'essayer son application dans les bassins non jaugés trop. Pour répondre à ces questions, une modélisation hydrologique spatiale simplifiée sur les sous-bassins versants est d'abord proposé où les paramètres sont essentiellement tirées de l'information disponible (surtout cartographique). La méthode de Kirchner (WRR, 2009) qui suppose que le débit à la sortie est la seule fonction de stockage du bassin versant, est spécifiquement étudiée dans le cadre des bassins versants Méditerranéens. L'étape suivante consiste à créer un nouveau modèle hydrologique SIMPLEFLOOD distribué sur la base de « top down » méthodologie de Kirchner dans la plateforme de modélisation JAMS. Les paramètres du modèle simple sont estimés à des endroits calibrés et une régionalisation se fait en fonction de la géologie. Le bassin versant est discrétisé en sous-bassins versants d'environ 10 km2. La dernière étape consiste à procéder à un couplage de données avec le modèle hydraulique MAGE 1D développé à IRSTEA HHLY tenir compte des effets de propagation de la rivière sur les hydrogrammes simulés. Le couplage est externe, ce qui signifie que les sorties du modèle hydrologique dans le système de modélisation de JAMS deviennent les entrées du modèle MAGE hydraulique. Les sorties sont les débits qui sont transférés dans le modèle de MAGE soit comme flux latéraux (provenant des terres adjacentes) et /ou entrées d'eau locales. L'application de la thèse est le bassin versant de l'Ardèche (2388 km ²), qui est l'un des sites pilotes français pour le programme international HyMeX (cycle hydrologique dans l'expérience de la Méditerranée, http://www.hymex.org/). La thèse proposée contribue également au projet FloodScale (multi-échelle d'observation hydrométéorologique et de modélisation pour la compréhension et simulation des crues éclairs (http://floodscale.irstea.fr/). L'application de la méthodologie Kirchner (2009) montre que les résultats de simulation des débits sont bonnes pour les bassins de granit, trouvés à être caractérisée principalement par des processus excès de ruissellement et d'écoulement sous la surface de saturation. L'hypothèse simple de système dynamique fonctionne particulièrement bien dans des conditions humides (pics et les récessions sont bien modélisés). D'autre part, la performance du modèle est moins bien représentée à l'été et les périodes de sécheresse où l'évapotranspiration est large et observations de bas-débits sont inexactes. Dans le bassin versant de l'Ardèche, les précipitations simulées correspondent bien à de stations de jaugeage observés et données de réanalyse SAFRAN pendant les périodes de non-végétation. Le modèle doit encore être amélioré pour inclure une représentation plus précise de l'évapotranspiration réelle, mais fournit un résumé satisfaisant du fonctionnement du bassin versant pendant les périodes humides et d'hiver. Le couplage du modèle hydrologique obtenue avec le modèle hydraulique MAGE 1D fournit des résultats satisfaisants mais les résultats sont si réciproques comme dans le cas du modèle hydrologique ou une équation d'onde cinématique simple pour le routage des flux existe. On peut dire que dans les situations ou débordement de la rivière est significative, le couplage serai crucial. / The scientific objective of the thesis is to progress in regional spatial hydrological modeling in the context of flash floods that represent one of the most destructive natural hazards in the Mediterranean region. Emphasis is put on catchment scaling issues and derivation of simplified equations and models applicable to basins of medium to large size to best describe landscape heterogeneity and process complexity. These are the key issues in facilitating the model set up in the context of the whole catchment and trying its application in ungauged catchments too. To address these issues, a simplified spatial hydrological modeling over sub-catchments is first proposed where parameters are essentially derived from available information (cartographic utmost). For this purpose, the Kirchner (WRR, 2009) method that assumes that discharge at the outlet is only a function of catchment storage is specifically studied in the context of Mediterranean catchments. The next step is to create a new distributed hydrological model based on the data driven methodology of Kirchner within the JAMS modeling framework. The parameters of the simple model are estimated at the gauged locations and a regionalization is done according to geology. The catchment is discretized into sub-catchments of about 10 km2. The final step is to proceed with data coupling with the MAGE 1D hydraulic model developed at HHLY to consider river propagation effects on the simulated hydrographs. The coupling is external, meaning that outputs from the hydrological model in JAMS modeling system become inputs to the hydraulic model MAGE. Outputs are discharge rates in the reach network that are transferred into the MAGE model as either lateral flows (coming from adjacent land) and/or local inflows. The case study of the thesis is the Ardèche catchment (2388 km²), which is one of the French pilot sites for the HyMeX international program (Hydrological Cycle in the Mediterranean Experiment, http://www.hymex.org/). The proposed thesis also contributes to the FloodScale project (Multi-scale hydrometeorological observation and modeling for flash floods understanding and simulation, http://floodscale.irstea.fr/ ). The application of the Kirchner (2009) methodology shows that resulting discharge simulation results are good for granite catchments, found to be predominantly characterized by saturation excess runoff and sub-surface flow processes. The simple dynamical system hypothesis works especially well in wet conditions (peaks and recessions are well modeled). On the other hand, poor model performance is associated with summer and dry periods when evapotranspiration is high and operational low-flow discharge observations are inaccurate. In the Ardèche catchment, inferred precipitation rates agree well in timing and amount with observed gauging stations and SAFRAN data reanalysis during the non-vegetation periods. The model should further be improved to include a more accurate representation of actual evapotranspiration, but provides a satisfying summary of the catchment functioning during wet and winter periods. The coupling of the resulting hydrological model with the MAGE 1D hydraulic model provides satisfying results. However, the results show that the timing and magnitude of simulated discharge with coupled model is as good as by the hydrological model with a simple kinematic wave equation for flow routing. We argue that in situations when there is a significant overflow in the floodplain the interest of the coupling with the hydraulic model becomes crucial.

La Senora Presidenta : Feminist policy-making by female Latin-American presidents?

Rudling, Adriana January 2009 (has links)
The following thesis is dedicated to the investigation of the comparative gender discourse of two of the current South American female Presidents: Michelle Bachelet, the first woman elected President in Chile for a four year term, in 2006 and Cristina Fernández de Kirchner, the first woman elected President in Argentina also for a four year term, but in 2007. Using secondary sources and critical discourse analysis, the study attempts to characterize their agenda on gender both before and after their election campaigns. Recognizing that a candidate must balance between many actors, as one of the principles of social constructivism runs, the essay presents a short history of the feminist movement in both countries and the current state that the movement finds itself in, either institutionalized or absorbed and fragmented by party politics. The conclusions that the study arrives to are that, of the two subjects, the one who has presented a more concrete and convincing stand on gender thanks to her political views, the space created for feminism by her coalition and the climate of her country, is Michelle Bachelet.

Néstor Kirchner (2003-2007) : rupture ou continuité du péronisme ? : Les mutations du populisme en Argentine / Néstor Kirchner (2003-2007) : a breach or a continuity with peronism ? : Mutations of populism in Argentina.

Doz, Emilie 15 November 2013 (has links)
Le 25 mai 2003, le peuple argentin assistait à l’investiture présidentielle du candidat du Frente Para la Victoria, Néstor Kirchner. Suite à la défection de Carlos Menem pendant l’entre-deux tours, il est élu avec 22% des suffrages. Malgré cette faible légitimité, il réussit à insuffler un changement certain dans la politique argentine. L’objectif de ce travail de thèse est de montrer comment Néstor Kirchner est arrivé à imposer un nouveau système de référence et à tourner la page du passé néolibéral qui a conduit le pays à l’effondrement. Pour cela, notre travail se concentre d’abord sur la présentation nécessaire du contexte économique et politique antérieur aux élections de 2003. Cette contextualisation permet de mieux cerner les conditions dans lesquelles Néstor Kirchner est porté au pouvoir. Ensuite, nous étudions la lutte idéologique qui se met en place, notamment à l’intérieur même du péronisme, afin d’identifier les processus qui permettent au discours kirchnériste de devenir discours dominant. Enfin, il s’agira d’étudier les points de ruptures ou de convergences du kirchnérisme avec le populisme et le péronisme afin de mieux le caractériser. De plus, le décès de Néstor Kirchner survenu le 27 Octobre 2010 a provoqué un véritable choc. Aussi, l’étude de la figure post mortem de Kirchner permet de prendre la mesure du phénomène K, dans le sens où il symbolise à la fois une réhabilitation du politique, une reconstruction de la nation argentine et une refondation du péronisme au XXIème siècle. / On 25 May 2003, argentinian population attended the presidential nomination of the "Frente Para la Victoria" party candidate, Néstor Kirchner. Thanks to the defection of Carlos Menem between the two rounds, he was elected with 22% of votes. Despite this weak legitimacy, he succeeded in impulsing changes in Argentina political agenda. The purpose of this thesis is to show how Néstor Kirchner managed to impose a new system as a new reference, and to move on from a neoliberal past which led the country to collapse. Therefore, our work first focuses on a necessary presentation of economic and political background prior to 2003' elections. Such contextualisation allows us to have a better understanding of the conditions in which Néstor Kirchner reached the presidency. Then, we study the ideological struggle taking place afterwards, particularly within peronism itself, in order to identify the processes allowing the kirchnerist line to become a dominant speech. Finally, we will focus on Kirchnerism’s breakpoints or convergences with Peronist populism for a better characterization. In addition, the death of Néstor Kirchner the 27th of october 2010 caused a real shock. Also, the study of the postmortem figure of Kirchner allows us to estimate the "K" phenomenon, in the sense it symbolizes as well a rehabilitation of politics as a reconstruction of the argentinian nation, or an overhaul of peronism in the XXIst century.

Anatomy of a pin-up : a genealogy of sexualized femininity since the Industrial Age

Lipsos, Eleni January 2013 (has links)
Pin-up images have played an important role in American culture, in both their illustrated and photographic configurations. The pin-up is viewed as a significant representational cultural artifact of idealistic and aspirational femininity and of consumerism and material wealth, especially reflective of the mid-twentieth century period in America spanning the 1930s to the 1960s. These images not only reflect great shifts in social mores and women’s social status, but also affected changes in both areas in turn. Furthermore, pin-up images internationally circulated in magazines, advertising and promotional material, contributed to the manner in which America was idealized in Europe and beyond. Crucially, they influenced how an eroticized and glamorous, yet unrealistic, example of femininity came to be generalized as a desirous model of femininity. In recent years there has been vital, though limited, scholarly research into the cultural and social impact of pin-up imagery, to which this thesis adds to. This thesis takes a genealogical approach, charting the development of popular female-centric “pin-up” imagery in America since the 1860s and up to the 1960s, and its resurgence since the 1980s onwards. In doing so this thesis aims to provide a social, political and cultural context to the emergence of a specific archetypal sexualized femininity, with the aim of challenging the tendency to dismiss sexualized imagery as “anti-feminist” or as trivial. Toward that end, I examine the complexity of intentions behind the production of “pin-up” images. In taking this revisionist approach I am better able to conclusively analyze the reasons for the resurgence and reappropriation of pin-up imagery in late-twentieth- and early-twenty-first-century popular culture, and consider what the gendered cultural implications may be.
